Fig. 4648 (from left to right): Taxus chinensis. Fig. 46: from Sichuan, Wang 22602 (A), with linear acute leaves. Fig. 47: from Hubei, China,,Cho 76099 (A), with oblong obtuse leaves characteristic of the species. Fig. 48: from W Hubei, Wilson 624 (A), morph with complanate leaves, showing bud-scale scars at base of branchlets, compare leaf shape with T. canadensis var. adpressa.

leaf surfaces discolorous, or yellowish orange on abaxial surface;
Leaves acute, apiculate, 1.5-2.0 mm broad, convex and smooth above;
blunt, 3.0-3.5 mm broad, plane and rugose on
52 (left): Taxus scutata, from Yunnan, Tsai 18464 (A),
showing loose spreading scales at base of branchlets.

Branchlets and leaves mostly not overlapping; leaves parallel at

T-sect. (Fig. 57) and view of abaxial surface of leaf (Fig. 58) showing
leaf margin (left) to midrib (right) , drawn from Curran s.n. (US).
Note contrast in color between upper and lower surfaces, and the
similarity to T. chinensis in leaf sections.
