GENUS =99. CUNNINGHAMIA.=

A genus of but one species. The cone-scales are very small, but the
bracts are large, thick, and serrate.

[Illustration: C. Sinensis.]

=Cunninghamia Sinensis=, R. Br. (CUNNINGHAMIA.) Leaves 1 1/2 to 2 1/2 in.
long, flat, rigid, numerous, alternate, somewhat serrulate; the leaf
gradually increases in width from the acute tip to the base, which is
decurrent on the stem and about 1/8 in. wide. Cones 1 to 1 1/2 in. long,
nearly globular, erect, very persistent, mostly clustered, sessile; the
scale is a mere transverse ridge, but the bract is large and prominent,
like a triangular-hastate, dilated leaf. A very handsome tree, from
China, which does not succeed very well in this region except in
protected situations.

GENUS =100. SCIADOPITYS.=

Cones elliptical or cylindrical, large, obtuse. Leaves evergreen,
somewhat flattened, arranged in distant whorls around the stems, and
spreading in all directions.

[Illustration: S. verticillata.]

=Sciadopitys verticillata=, S. and Z. (UMBRELLA-PINE.) Leaves 2 to 4 in.
long, 1/6 in. wide, linear, obtuse, smooth, persistent, sessile, entire,
in whorls of 30 to 40 at the nodes and extremity of the branches. Cones
3 by 1 1/2 in. Scales wedge-shaped, corrugated, overlapping, coriaceous,
persistent; bracts adherent, broad, and smooth. A beautiful, tall,
conical, slow-growing tree, with the branches whorled. Recently
introduced; hardy in the New England States.

GENUS =101. TAXODIUM.=

Leaves deciduous, spreading, in 2 ranks. Flowers monoecious on the
same branch, the staminate ones in spikes, and the pistillate ones in
pairs below. Cones globular; the scales peltate, angular, thick, firmly
closed till ripe, with 2 angular seeds under each.

[Illustration: T. distichum.]

=Taxodium distichum=, Richard. (SOUTHERN OR BALD CYPRESS.) Leaves
deciduous, flat, linear, 1/2 to 3/4 in. long, in 2 rows on the slender
branchlets, forming feather-like spray of a light green color. This
whole spray usually falls off in the autumn as though a single leaf.
Cones round, closed, hard, 1 in. in diameter. A fine, tall (100 to 125
ft. high), slender, spire-shaped tree with a large, spreading, rigid
trunk, 6 to 9 ft. thick, and peculiar conical excrescences (called
knees) growing up from the roots. Wild from Maryland south, and
cultivated and hardy in the Middle and many of the Northern States.
