59. PTEROCAULON. Ell. sk. 2. p. 333 (1824); DC. prodr. 5. p. 453.

Heads many-flowered ; the fertile flowers filiform, pistillate, in several
series; the perfect flowers in the centre (or intermixed with the others, Ell.),
mostly sterile. Scales of the oblong involucre imbricated in several series,
appressed or with slightly squarrose points, caducous. Receptacle mi-
nutely fimbrillate or hirsute. Corolla of the fertile flowers 3-toothed ; the
sterile 5-cleft at the summit. Anthers bicaudate, somewhat exserted. Ache-
nia angled, pubescent with appressed hairs. Pappus of numerous capillary
scabrous equal bristles, longer than the involucre. — Perennial herbs, or
slightly shrubby plants (chiefly natives of tropical America), with a some-
what tuberous rhizoma. Leaves alternate, lanceolate, entire or denticulate,
very densely tomentose beneath, the margins decurrent along the stem into
continuous foliaceous wings. Heads sessile, densely crowded in simple or
compound spikes. Flowers usually white.

1. P. pycnostachyum (Ell.) : stem herbaceous, simple; leaves lanceolate,
undulate-denticulate, glabrous above ; heads in a dense continuous spike ;
scales of the involucre silky- tomentose, squarrose at the apex. — Ell. I. c. ;

60. CALYMMANDRA.

Heads subglobose, snbsessile, collected in small axillary clusters, many-
flowered, heterogamous ; the flowers all fertile ; the pistillate in many series,
in the axils of narrow and plane linear or somewhat spatulate scarious (vil-
lous-lanate) chaff of the receptacle, with a filiform truncate corolla; the per-
fect 5 in a single central series, each enclosed in an oval convolute woolly
chaff; the short and somewhat inflated minutely 4-toothed corolla more or
less exserted. Scales of the involucre few, similar to and passing into the
chaff. Receptacle conical, punctate. Anthers with very short tails. Branch-
es of the style short; in the perfect flowers oblong, flat ; in the pistillate fili-
form. Achenia oval-oblong, nearly terete, very smooth, destitute of pappus,
those of the perfect flowers similar, but enclosed by the subtending chaff. —
A small annual herb, branched from the base, clothed with a very white and
silvery appressed wool; the branches slender, somewhat simple, erect, bear-
ing small bracteate or irregularly involucrate clusters of few heads, closely ses-
sile in the axils of linear-oblanceolate or narrowly spatulate entire leaves; the
heads themselves (about a line long) on short pedicels concealed by the wool.

their axils. Chaff falling away when the achenia ripen, all nearly equal hi
length, scarious, glabrous towards the base, that of the perfect flowers woolly
throughout, somewhat herbaceous, obtuse, shorter than the flowers, but in-
vesting the achenia, just as those of Micropus are enclosed by the scales of
the involucre. In the latter, the exterior and pistillate flowers are thus in-
vested : in this remarkable genus, on the contrary, the central staminate
(and fertile) flowers are enclosed, to which circumstance the generic name
alludes.



61. FILAGINOPSIS.

Heads subglobose-ovoid, collected in dense umbel liform clusters, many-
flowered ; the fertile flowers pistillate, numerous, and in many series in the
axils of the linear-oblong and obtuse (woolly-tipped) flat and scabrous equal
chaff of the receptacle, with a filiform truncate corolla ; the 2-6 central sta-
minate, with a tubular-infundibuliform 4-toothed corolla, sessile and with no
vestige of an ovary, subtended by as many of the cbafly scales of the recep-
tacle, and nearly equalling them in length. Involucre of few scales en-
tirely similar to the chaff of the receptacle, and only distinguishable by having
no flowers in their axils : involucrate bracts mostly 5, in a single series, ob-
ovate-spatulate, herbaceous, with scarious margins, very woolly. Receptacle
flat or somewhat convex, papillose-punctate. Style in the staminate flowers
undivided ; in the fertile with short filiform branches. Achenia oval, smootk
and glabrous, slightly obcompressed (that is parallel with the chaff), entirely
destitute of pappus. — Annual woolly herbs, with the aspect of Filago (natives
of Mexico and Texas), much branched from the base, diffuse. Leaves ob-
long-spatulate, entire, sessile. Heads in involucrate (simple or proliferous)
woolly gloraerules, terminating the branches.

This genus differs from Evax in the broad and flat receptacle, obtuse chaff, Ace.;
from the Diaperia of Nuttall in the roundish very many-flowered heads, the narrow
chaff numerous in each series, the sessile sterile flowers, Ace.

1. F. multicaulis : glomerules often proliferous; chaff of the sterile flowers
linear-spatulate, somewhat herbaceous and woolly throughout, slightly io-
volving the entirely glabrous corolla. — Evax multicaulis, ±>C. ! jrroar. 5. p»
459. E. verna, Raf.! herb.

Texas, Berlandier I Drummond ! Dr. Leavenworth ! (the former also ob-
tained it in Mexico.) — Plant 3-6 inches high, with rather slender diffuse stems
and branches, clothed with long loose wool. Leaves one-fourth to half an
inch long ; the involucrate ones unequal and often shorter than the irregular
clusters. Heads ovoid ; the chaff all but the inner series glabrous except at
the summit, where the long wool is densely matted and coherent, while the
base separates from the receptacle when the achenia are mature.

2. F. Drummondii : glomerules seldom proliferous : chaff of the sterile
flowers entirely similar to that of the fertile, or wanting; the corolla (sterile),
like the chaff, clothed with long woolly hairs at the summit.

Texas, Drummond ! — Plant 4-8 inches high, more loosely branched than
the preceding, which it exceedingly resembles. Heads fewer in a cluster
and rather larger, very many-flowered, hemispherical-obovoid ; the oblong-
linear chaff all similar and of the same length, clothed towards the tips with

rather shorter wool, so that they separate readily when they fall away ; the
4 or 5 sterile corollas naked, connected by the crisped woolly hairs which
grow on the dilated limb.



62. DJAPERIA. Nutt. in trans. Jmer. phil. soc. (». ser.) 7. p. 337.

Heads fusiform-oblong, disposed in sessile glomerules of 4-5 together,
which are collected in large capitate and bracteate compound clusters termi-
nating the stem or simple and mostly proliferous branches ; the fertile flow-
ers 8-12, pistillate, in the axils of the chaff of the receptacle, with a much
attenuated filiform truncate corolla ; the 2-3 central staminate, with a tubu-
lar-infundibuliform minutely 4-toothed corolla, destitute of ovaries, each
supported by a filiform stipe and enclosed in a chaff of the receptacle. Scales
of the involucre and the chaff of the small convex receptacle scarious, oval,
broad and large for the size of the head, closely and somewhat distichously
imbricated and wrapped around each other, the inner successively longer ;
the 2-3 innermost chartaceous, attenuate at the base, woolly towards the
apex, each convolute and separately enclosing a sterile flower. Style in the
sterile flowers undivided ; in the fertile with 2 filiform branches. Achenia
obovoid-oblong, obcom pressed, glabrous, destitute of pappus. — A small an-
nual erect woolly herb, with spatulate-oblong or linear-spatulate numerous
sessile entire leaves; the stems simple or often branched from the base, ter-
minated by the large irregularly involucrate compound head ; from which
arise 1 to 5 or 6 simple branches, terminated by simple but usually smaller
compound heads, in the manner of the Herba impia ; and these rarely again
proliferous. Proper heads and primary clusters more or less bracteate.

D. prolifera (Nutt. ! 1. c.) — Evax prolifera, Nutt. ! in DC. prodr. 5.

Banks of Red River, Arkansas, Nutlall ! Dr. Leavenworth ! June-Aug.—
Stems stout, rigid, 2-5 inches high, terminated by a capitate cluster one-
half to three-fourths of an inch in diameter, including a large number of small
heads: some of the branches when numerous often arising below this com-
pound head. Scales of the involucre few, entirely similar to the chaff, and
passing into the latter, but shorter, and woolly externally : the chaff of the
fertile flowers glabrous or slightly tomentose-ciliate : that of the sterile longest
and more rigid, much longer than the slender corolla it encloses; the filiform
stipe of the latter fully half its own length.

63. MICROPUS. Linn. ; Gartn. Jr. t. 164 ; Schkvhr, handb. t. 267.

Heads collected in axillary sessile clusters, several-flowered ; the fertile
flowers 5-7, in a single series, pistillate, with a filiform corolla, enclosed in
the inner scales of the involucre ; the 3-7 central staminate, with an infundi-
buliform 5-toothed corolla, naked, destitute of ovaries. Receptacle small and
flat. Involucre in 2 series, each of 5-7 scales ; the exterior scarious, flatfish,
spreading, bracteiform ; the interior (perhaps rather to be considered chaff of
the receptacle, as described by Nuttall) infolded and laterally compressed*

boat-shaped and very gibbous, enclosing the fertile flowers, and forming a
permanent cartilaginous covering to the smooth obovate and gibbous com-
pressed achenia. Pappus none. — Low woolly herbs with the aspect of
Filago or Gnaphalium.

§ Fructiferous scales of the involucre not echinate, woolly when young.—
Bombycilaena, DC.

f 1. M. California* (Fisch. 6c Meyer) : clusters lateral and terminal ;
fructiferous scales compressed-navicular, semi-obcordate ; the inner margin
straight, terminated by an erect mucroniform appendage with a scarious
apex— Fisch. Sf Meyer, ind. sem. St. Pctersb. 3835, p. 42; DC. prodr. 7.
(mant.) p. 283.

(3. angustifolia : slender ; leaves linear, acute ; heads very woolly when
young ; exterior or bracteate involucral scales oval, concave, scarious with a
linear green centre. — M. (Rhyncholepis) angustifolius, Nutt. ! in trans. Amer.
phil. soc. I. c.

California at Bodega, Fischer % Meyer. (3. St. Barbara, Nuttall /—Said to
resemble M. erectus, but the heads with a more scattered and shorter wool ;
while Mr. Nuttall's plant is more slender than that species, the young heads
with a longer wool ; but the fruit &c. exactly corresponding to the character
of the Russian botanists, who do not notice the leaves, dec. Perhaps there are

\ two nearly allied Californian species.

64. PSILOCARPHUS. Nutt. in trans. Amer. phil. soc. (n. ser.) 7. p. 340.

Heads solitary or clustered, many-flowered ; the fertile flowers 8-30 in
several series, pistillate, with a filiform corolla, each enclosed in an involute
involucral scale or chaff of the receptacle ; the 5-8 central staminate, wiih a
dilated infundibuliform 4-5-toothed corolla, destitute of ovaries, naked. Re-
ceptacle subglobose ; the chaff and similar involucral scales (as the outermost
may be deemed) membranaceous, woolly, reticulated, infolded, and cucul-
late, forming thin obovoid or somewhat gibbous loose coverings to the very
smooth oblong terete or slightly compressed achenia. Branches of the style
short and filiform, in the sterile flowers minutely hairy. Pappus none.—
Very small diffusely branched and depressed woolly annuals, with the aspect
of Evax, 6cc. (natives of the western coast of America) ; with linear or
spatulate-oblong entire and sessile leaves, which are alternate, and irregu-
larly involucrate around the terminal or lateral sessile heads or clusters.

This certainly distinct genus is well described by Nuttall j except that, although
he mentions a beak or uncinate tips to the fructiferous chaff in some species, he has
not alluded to the true structure of this inconspicuous appendage, which in fact
exists in all the species. It consists of a small hyaline scale, forming the organic
apex of the fruit-enclosing chaff, and, as it were, articulated with it at the summit of
the anterior fissure : at first it is erect or spreading ; but afler impregnation it is more
or less indexed, covering the fissure like an operculum. In P. tenellus, this scale is
broad, ovate, and nearly as large as the chaff itself at the time of impregnation : in
P. Oreganus it is similar in form, and in the full-grown chaff about half the length
of the fissure ; in P. globiferus and the nearly allied P. brevissiuius, it is smaller
in proportion to the chaff, ovate-oblong, and apparently somewhat deciduous.

leaves oblong-linear, the floral ones broader, obtuse; fertile flowers 20 or
more ; the obovoid inflated fructiferous chaff forming globose very woolly
heads, lateral and terminal. — Micropus globiferus, Bertero, in DC. prodr. 5.
p. 460 ?

St. Barbara, California, Nuttall! April. — "Plant not an inch high,
spreading out 5 or 6 inches :" the woolly bracteate heads numerous, nearly
one-fourth of an inch in diameter ; the woolliness of the leaves somewhat
deciduous: the inflated fruit-bearing chaff between 1 and 2 lines long. — Also
a native of Chili, if it is really the Micropus globiferus of Bertero, which is
uncertain, although that species doubtless belongs to this germs.

2. P. brevissimus (Nutt. ! 1. c.) : stem minute, simple, producing mostly
a single very woolly head ; fertile flowers 8-10 ; the fructiferous chaflobovoid-
oblong ; leaves oblong-lanceolate, acute.

"Plains of the Oregon River, in inundated tracts. — Extremely dwarf
(perhaps not always so) ; about 4 lines high ; the solitary capitulum, though
rather large, sessile on about the third set of leaves, and so downy as to look
like a pellet of cotton." Nuttall. — Very nearly allied to the preceding. Mr.
Nuttall suspects it may possibly prove to be the Micropus minimus of De
Candolle.

3. P. Oreganus (Nutt. ! 1. c.) : canescently tomentose throughout, dif-
fusely branched and procumbent; leaves linear; fertile flowers 20 or more ;
fructiferous scales obovoid, tomentose.

'* Inundated places, near the Oregon and the outlet of the Wahlamet.—
Nearly allied to P. globiferus ; but with much narrower leaves ; with none
of the long arachnoid hairs of that species ; the scales of the receptacle also
smaller." NuttalL

4. P. tenellus (Nutt. ! I.e.): tomentose-canescent ; the base of the ascend-
ing clustered stems and the lower leaves becoming glabrous ; lower leaves
spatulate-linear ; the upper and floral ones oblong-spatulate ; heads small,
mostly terminal ; fertile flowers 20 or more ; fructiferous scales obovoid-ob-
long, gibbous, tomentose. - H

St. Barbara, California, Nuttall! April. — Plant l-2 A inches high, with
the stems slender. Heads about 2 lines in diameter. Achenia acute at
each end.

65. STYLOCLINE. Nutt. in trans. Amer. phil. soc. (n. set.) 7. p. 338.

Heads subglobose, many-flowered ; the fertile flowers pistillate, in several
series included in a carinate fold of the chafF of the receptacle, with a very
slender and filiform truncate corolla ; the 3-4 central staminate, with a tubu-
lar minutely 5-toothed corolla, destitute of ovaries, naked. Receptacle slen-
der and elongated, cylindrical; the chaff imbricated, broadly ovate, concave,
scarious, with a green herbaceous carinate-saccate keel in which the fertile
flowers are enclosed, woolly towards the base ; the scales of the involucre
about 5, similar, but destitute of the saccate keel. Achenia very smooth,
somewhat laterally compressed, acute at the base, slightly lunate. Pappus
of the fertile flowers none ; of the sterile composed of 3-5 barbellate-scabrous
bristles as long as the corolla. — An annual tomentose woolly low herb, dif-
fusely branched and decumbent, with small linear entire sessile leaves.
Heads (about 3 lines in diameter, yellowish-white) in sessile clusters of 3-6
together at the extremity of the branches and in the upper axils.

linear ; in all the states being either obtuse or acuminate-mucronate, enure,
or with one or two sharp salient teeth near the base, or remotely denticulate
throughout : the exterior scales of the involucre are often rather appressed ;
the inuer either canescent, or nearly glabrous with ciliate margins, and the
spinous points of the chaff are at first rather shorter than the flowers.
Hence perhaps B. argentea, B. Peruviana, and Buphth. lineare, WUld. are
