Pseudotaxus liana was described from Guangxi and at the same time recorded from Hunan and Jiangxi. In the protologue (Silba, Phytologia 81: 327. 1996, as "liiana"), it was said to differ from P. chienii in its broadly ovate or ovate-oblong leaves, 1.3-2.8 cm × 3.5-5.5 mm, which are thick and leathery; it was also compared with two species in the Podocarpaceae: Podocarpus brassii Pilger, from Indonesia (Irian Jaya) and Papua New Guinea, and Prumnopitys harmsiana (Pilger) de Laubenfels, from South America. Further study is needed to ascertain whether it is distinct from Pseudotaxus chienii and, if so, to settle its generic, and possibly also familial, placement. If it is distinct, then some of the records of P. chienii may in fact belong to the new species.

Pseudotaxus chienii, the whiteberry yew[1] (Chinese: 白豆杉; pinyin: báidòushān; lit. 'white bean conifer'), is a species of plant in the yew family, Taxaceae. It is the sole species in the genus Pseudotaxus, but closely related to the other yews in the genus Taxus. It is endemic to southern China, occurring in northern Guangdong, northern Guangxi, Hunan, Southwest Jiangxi and southern Zhejiang.
Like other yews, it is a small coniferous shrub or small tree, reaching 2–5 m tall with reddish bark. The leaves are lanceolate, flat, 1–2.6 cm long and 2–3 mm broad, dark green above, with two white stomatal bands below; they are arranged spirally on the stem, but with the leaf bases twisted to align the leaves in two flat rows either side of the stem. The conspicuous white stomatal bands on the harder, stiffer (less soft) leaves readily distinguish it from the yews in the genus Taxus.
It is dioecious, with the male and female cones on different trees. The female (seed) cones are very similar to those of Taxus species, but the aril is white when mature, not red; they are 5–7 mm long and wide. The male (pollen) cones are globose, 3–4 mm diameter.
It is grown as an ornamental plant in southern China and occasionally elsewhere.
