times 2 in diameter, generally divided near the ground by irregular deep fissures into
broad rounded ridges, many erect contorted branches forming a broad open head, slender
light yellow-green branchlets covered after the falling of the leaves with thin light red-
brown scaly bark; more often with numerous stems spreading from the ground and fre-

eaten by Indians fresh, or ground and baked into cakes.

Distribution. Southwestern Wyoming (J. Knightii A. Nels.), southwestern Idaho (Po-
catello, Bannock County), western Colorado, eastern Utah, and western New Mexico to
northern Arizona and southeastern California at altitudes from 5000 to 8000; the most
abundant and generally distributed tree of the Great Basin, forming in the valleys open
forests of stunted trees and shrubs, and on arid slopes more numerous and of larger size
in dense nearly pure forests.

elongated rigid callous tips. Flowers: male slender, composed of 16-20 stamens, with
ovate pointed connectives prominently keeled on the back; female with acute or acumin-
ate spreading scales. Fruit subglobose, dull red-brown, more or less covered with a glau-
cous bloom, i' I' in diameter, with a close firm skin and thick resinous flesh; seeds
4-12, pointed at apex, slightly ridged, often abortive and distorted, |'-j' long, with 2

fissured or scaly bark, light-colored durable close-grained wood, slender branchlets, linear-
lanceolate entire rigid acuminate spirally disposed leaves, usually appearing 2-ranked
by a twist in their short compressed petioles and persistent for many years, and small
ovoid acute buds. Flowers opening in early spring from buds formed the previous au-
tumn, dioecious or monoecious, axillary and solitary, surrounded by the persistent decus-
sate scales of the buds, the male composed of numerous filaments united into a column,

1. TORREYA ARN.
Tumion Raf.

Glabrous foetid or pungent aromatic trees, with fissured bark and verticillate or oppo-
site spreading or drooping branches. Leaves thin, long-pointed, abruptly contracted
at base, dark green, lustrous and slightly rounded above, thickened and revolute on the
margins, with pale bands of stomata on each side of the midvein on the lower surface.
Flowers dioecious; the male crowded in the axils of adjacent leaves, on shoots of the
previous year, oval or oblong, composed of 6 or 8 close whorls each of 4 stamens, sub-
verticillately arranged on a slender axis; filaments stout and expanded above into 4 globose
yellow pollen-sacs united into a half ring, their connectives produced above the cells; the
female on shoots of the year less numerous and scattered, sessile, the ovule surrounded by
and finally inclosed in an ovoid urn-shaped fleshy sac, and becoming at the end of the second
season an oblong-ovate yellow-brown seed, rounded and apiculate at apex, acute and
marked at base by the large dark hilum; seed-coat thick and woody, its inner layer folded
into the thick white albumen, surrounded and finally inclosed in the thick green or purple
enlarged disk of the flower composed of thin flat easily separable fibers, splitting longitudin-
ally when ripe into two parts and separating from the basal scales persistent on the
short stout stalk of the seed.

Torreya is now confined to Florida and Georgia, western California, Japan, the island of
Quelpart, and central and northern China. Four species are recognized. Of the exotic
species the Japanese Torreya nucifera S. &Z. is occasionally cultivated in the eastern states.

The genus is named in honor of Dr. John Torrey, the distinguished American botanist.
