Amentotaxus

Pilger 1917 (p. 41)

Common names

Catkin-yew; sui hua shan shu [Chinese].

Taxonomic notes

A genus of six species:

"Although Page (in Kubitzki, Fam. Gen. Vasc. Pl. 1: 299-302. 1990) included it in the Cephalotaxaceae, molecular data indicate very strongly that it is the sister genus of Torreya, which is similar in the size and shape of its seed and in usually having bilaterally symmetric clusters of pollen sacs" (Fu et al. 1999). Cheng et al. (2000) corroborated this conclusion using chloroplast matK gene analysis, and separately using nuclear data (nrITS sequences).

Description

"Evergreen, dioecious shrubs or small trees, allied to Cephalotaxus, differing from it in male catkins which are thin, pendent and in groups (2-4 together) and in solitary ovules. Shoots opposite. Needles opposite, leathery, acuminate, with 2 bluish stomata bands on the lower surface. Fruit drupe-like, reddish, aril not entirely enclosing the seed, but open at the apex" (Vidakovic 1991).

Distribution and Ecology

China, India, Vietnam and Taiwan (Farjon 1998).
