White-berry yew; 白豆杉 bai dou shan [Chinese].
The genus was described as Pseudotaxus W.C. Cheng 1947 and then as Nothotaxus Florin 1948.
P. chienii subsp. liana may win acceptance as a valid subspecies. The Flora of China (Fu et al. 1999) is inconclusive, and I have seen no later analysis.
Shrubs to 4 m tall. Crown not described. Bark gray-brown, peeling in strips. Branchlets round, green or yellow-green in first year, dark green in second year. Leaves borne at 40-45° to axis when young but at 50-90° on mature trees; petiole absent or less than 1 mm; blade bright green adaxially in 1st year, thereafter dark green, linear, straight or slightly falcate, 1-2.6 cm × 2-4.5 mm, not leathery, midvein 0.4 mm wide, stomatal bands 0.5-1.1 mm wide, broader than or about as wide as marginal bands, in 9 rows on young plants increasing to 13-19 rows on adult plants, marginal bands 0.2-0.3 mm wide. Aril 5-7 mm diameter with a single ovoid seed, 5-8 × 4-5 mm. Pollination occurs from late March to May, seed maturity in October (Fu et al. 1999).
China: N Guangdong, N Guangxi, NW and S Hunan, SW Jiangxi, S Zhejiang; cultivated as an ornamental in Zhejiang (Fu et al. 1999). Rare understory shrub in cool, moist temperate montane forest dominated by evergreen or deciduous angiosperms (Farjon 1998).
The wood is used as a carving material and for making utensils (Fu et al. 1999).
