Taxonomic notes

Syn.: C. harringtonia var. wilsoniana (Hayata) Kitam. 1974; C. sinensis var. wilsoniana (Hayata) Fu et Li 1997 (Farjon 1998). The molecular analysis by Hao et al. (2008) showed that the clade C. harringtonia - C. koreana - C. wilsoniana is monophyletic, and that the latter two species could be treated as varieties of the former.

Description

Trees to 9 m with pendant branches (Tripp 1995). "Leaves linear, slightly falcate, spreading in 2 ranks, 3-4 cm. long, 2.5-3.0 cm. wide, apex acute, base narrowed, dark green above, with two grayish white stomatic bands beneath. Seeds drupe-like, ovoid to obovoid, about 2.5 cm. long, becoming dark purple at maturity, ripening in September. Trunk bark dull reddish brown, thinly flaky, flakes about 0.4 mm. in thickness; lenticels inconspicuous; outer bark 1-1.5 mm. thick, fibrous, with grayish brown and somewhat tiered cross-sections; newly formed periderm deep purplish red, phelloderm almost inconspicuous; inner bark 3-4 mm. in thickness, fibrous, more or less tiered; cambium and newly formed phloem indistinct. Freshly cut sapwood pale yellowish orange, wood rays inconspicuous" (Liu 1970). Differs from C. sinensis in that at least some leaves are tapered from a point above middle of blade but well below the apex, the leaves being ca. 10 × as long as wide (Fu et al. 1999).
