rarely, distichous ; usually linear or subulate, close and imbricating or
more apart, rarely distant. Sporangia bi- or tri-valved, single, sessile
and axillary in the leaves of the normal or modified branches, or in
special spikes. Spores of one kind, abundant and dust-like.

Four genera comprise this order, but only two of them
are represented in Guiana. The others — Phylloglossum
and Tmesepteris — are confined almost entirely to Aus-
tralia and the adjacent islands, Tmesepteris reaching to

California.

Genus L— Lycopodlum. Linn.

Sporangia reniform, one-celled, bivalved, axillary in the normal or
modified leaves of the outer parts of the branches, or in the imbricating
scales of special spikes. Leaves of one or two kinds, multifarious, rarely
distichous or biserial, generally close and often imbricating. Stems and
branches mostly terete, dichotomously or pinnately branched, leafy
throughout.

These are the true club-mosses, and their aspeft, except
in a iew instances, is very different from that of their allies
the Selaginellas, from which they are technically distin-
guished by having only one kind of spores and spore-cap-

sules. They number about a hundred species, which are
spread over the torrid and warmer regions of the globe, but
most concentrated in the equatorial belt. Some of the spe-
cies range widely in both the old and new worlds. They
are divided in their habits of growth into two divisions —
terrestrial and epiphytal. The former in Guiana grow in
moist ground generally, either open to the dire6l sunlight
or in forest shade. Two or three species, however, ap-
pear to prefer well-drained ground. Both are ere6l, or
prostrate in growth, and more or less gregarious. Of the
epiphytal, some are stri&ly pendent, others have a ten-
dency to be pendent with the gradual lengthening of
their weak flexible branches, while still maintaining ver-
tical growth. These generally grow in forests on the
branches of trees.

state they are from 1-4 li. 1. so far as I have seen, but may
be in some cases more, as species from Venezuela and

IM Thurn n. 230, base of the cliff, Roraima. This
species resembles in general aspefct that preceding it agood
deal, and closely in habit, but is more slender and much
more pliant and flaccid, the leaves more apart, narrowerand
more acuminate, and pale in colour, and it seems to
grow very much longer, — no doubt, from the branches of
trees. Its general distribution I find I have overlooked,
and no books within my reach show it.

and stiff, contracted laterally or convolute, £-i in. 1. £-£ li. w., freely
overlapping, sharp, even-margined. Sporangia reniform, £ li. w., the
lips closed, visible between the narrow leaves.

This species is peculiar for its long tail-like branches,
which only infrequently fork, and that reach from 1-3 ft. 1.
When on trees it is stri6lly pendent, but it grows also
on the ground, in leaf-mould and in other rubbish, and
then the stems become constrifted here and there and
root at the place. The leaves remain fixed in a line
with the rachis, not at all spreading, and their convolute
condition gives them a very narrow stiff and sharp
appearance. %

Jenman, n. 373, Corentyn River ; n. 2059 Canje
River ; growing on the branches of trees. The leaves
are very close and spread in various direttions, the outer
part of the branches often appearing to have longer
ones than the inner parts, but it is only in appearance
and due to the angle at which they spread. The species
is a charafteristic one, variable in its extent of branch-
ing, with a more or less upright (not pendent) but
ultimately, as in reflexutn % spreading growth. The
leaves also vary in width, some plants from this cause
having a much finer aspeft than others.

General distribution — West Indies and tropical main-
land of America to Peru. Also Madagascar.

11. Lycopodium taxi folium, Linn.— Gr. Fl. B. W. I. p. 647. — Stems
ribbed, leafy from the base, pendent, spreading, or more or less ereft,

outward. Leaves close but not crowded, straight linear-acuminate,
even-edged, efe&o-spreading, several serial, Hat, firm but not stiff,

Nearest linifoliutn, but with much stiffer and thicker
stems and firmer stiffer leaves. The habit of the type
varies a good deal. Young plants are quite erett, and
grow either on the ground or trees, though generally on
the latter ; older plants have laxly spreading branches,
while others again are quite pendent. The primary
stems are £ in. thick, and have 5-7 ribs, and conse-
quently the leaves as they are attached to the ribs

Colle&ed by Drake in British Guiana. This is some-
thing like a small state of passer inoides, of erefi habit
and short branches. It is several times forked, but the
whole plant reaches only generally 6 to 8 inches high,
so that the space between the bifurcations is relatively
very short. It is a terrestrial species.

inch. L. fiasserinoides, as I have before pointed out, in
some of its states comes near it, but in that the stems are
never so slender or flaccid, nor the leaves so few in series or
so loosely placed on the ribs. The specimen from Appun,
quoted above, has nearly 100 final branches, all devel-
oped by repeated forking from a single primary stem.

General distribution — Tropical America abundant,
from the West Indies to Brazil.

This small genus consists of only two species, which
however make up for the paucity of type in their abun-
dance and wide distribution. They are small and twiggy
plants ; starting from a simple base, and repeatedly fork-

distant and very inconspicuous leaves. Only one of
them, the commonest, has yet been found in Guiana.

branches. It was first gathered in this country by
SCHOMBURGK. It grows on banks, in the fissures of
rocks, and between the roots of trees. At the Botanic
Gardens, where it has never been cultivated, it comes up
frequently in the plant pots.

General distribution. — America, from Cuba to South
Brasil ; tropical Africa, Asia, and Polynesia.
Order ZZ. Eguiietaoea.

Rootstock creeping. Stems ereft, cylindrical, longitudinally furrowed,
jointed at intervals, hollow except at the joints, which terminate in a
completely circular monophyllous dentate margined sheath. Branches
simple, springing through the lower part of the sheaths, whorled and
spreading. No distinct leaves. Fructification terminal, on simple
stems, in cone-shaped heads, which are composed of several horizontal
tiers of peltate stipitate scales that bear on their underside 6-9 pale mem-
branous micro-sporangia that open longitudinally in a 'slit on the inner
side. Spores minute, green, united to elastic wool-like threads (elaters)
that are spontaneously irritant while dry.

A single genus represents this order, numbering about
thirty species, the principal part of which are spread
through the north temperate zone, where they are in
several European countries common and well known
marsh plants, which in Britain go by the name of horse-
tails and paddock-pipes. They form no leaves proper, but
these organs are represented by the membranous sheaths
of the joints. The branches are produced after the
stems have developed, and they grow through the base
of the sheaths. There is but one known Guiana species.

Gatherered by Appun, but his label bears no number
or locality. It is a very slender species, with small
twig-like branches, which are usually simple from the
base, but occasionally are branched verticellately from one
or more of the joints. The slender rootstock extends
freely in the- ground, and the tufts of shoots are thrown

The Hurricane of 1830 in Si Vincent; by an
Eye-witness.

Edited by Mary Browne.*
* * *****

| HE month of August is considered one of the
hurricane months, and although this island had
not for half a century experienced anything of
the kind (for whilst other islands have suffered materially,
St. Vincent has invariably escaped) yet it is usual for all
the merchant vessels to leave on or before the ist of
August, otherwise the insurance is doubled. On Monday,
the ist of August, I left Kingston and at 12 o'clock
wheeled my horse's head homewards. Passing the Bay of
Calliaqua, and which is 3 miles from Kingston, I ob-
served several of the merchant vessels getting under weigh
for England. During the preceding week and up to
within a short period of its occurrence, we had nothing to
indicate the approaching hurricane. On the Wednes-
day evening it was perfeflly still, calm, and serene, and
we had taken a drive to Langley Park, as if to take a
last look at the beautiful scenery — the luxuriant fields of
canes promising an abundant harvest. We remarked
on our return that the weather was close and sultry.
After midnight the wind began to rise, and with the
earliest dawn of the morning, about 5 o'clock, I looked

every moment! larger limbs were broken off, the sea
began to run mountains high, and to present the grand-

the waves rising to such an astonishing height that it
