Trees -- North America
Glabrous fœtid or pungent aromatic trees, with fissured bark and
verticillate or opposite 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 diœcious; 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, subverticillately 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 longitudinally 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.

[Illustration: Fig. 90]
Leaves slightly falcate, 1½′ long, about ⅛′ wide, somewhat rounded, dark
green and lustrous above, paler and marked below with broad bands of
stomata. Flowers appearing in March and April; male with pale yellow
anthers; female broadly ovoid, with a dark purple fleshy covering to the
ovule, ⅛′ long, and inclosed at the base by broad thin rounded scales.
Seed fully grown at midsummer, slightly obovoid, dark purple, 1′—1¼′
long, ¾′ thick, with a thin leathery covering, a light red-brown
seed-coat furnished on the inner surface with 2 opposite longitudinal
thin ridges extending from the base toward the apex, and conspicuously
ruminate albumen.
