Cephalotaxus griffithii Hook.f., Fl. Brit. India 5: 648 1888. as per A taxonomic revision of the genus Cephalotaxus (Taxaceae) (2013);

This species has a wide but scattered distribution in southeast Asia being recorded from southern and western China: Guangdong (Xingyi), Guangxi, Yunnan, SE Xizang [Tibet]; northern Myanmar [Burma]; northeast India: Arunachal Pradesh, Megalaya (Khasi, Jaintia, Mishmi Hills and Naga Hills), Assam (Manipur, Nagaland); northern Thailand; Viet Nam; and Lao PDR. The subpopulations in China and Thailand often only occur in low densities and in remote areas. Parts of the Indian subpopulation are sometimes referred to as C. griffithii. With such a wide range, the extent of occurrence is well in excess of the thresholds for a threatened listing and there is insufficient data available to calculate the area of occupancy.

Throughout its range, C. mannii is restricted to small subpopulations in which the largest trees (to 30 m tall and over 100 cm d.b.h.) are often targeted for their timber. Stripping of bark is often fatal to the trees and this type of harvest is unsustainable. Logging is also unsustainable as this species grows slowly. The principal threat, however, is conversion of habitat to agriculture and resulting in severe forest fragmentation. There are not enough forest reserves of sufficient size and integrity to safeguard this species at present (Fu and Jin 1992, Nguyen et al. 2004). Fragmentation also makes the remaining stands more susceptible to natural disasters such as typhoons. It is likely that habitat reduction has accelerated in recent years.

Cephalotaxus griffithii, commonly called Griffith’s Plum Yew, is a coniferous shub or small tree in the plum yew family.

It is endemic to northern India, northern Myanmar and the western Sichuan Province in China.

(From Wikipedia (Cephalotaxus griffithii) on 24.12.13)

Cephalotaxus mannii is a species of plum-yew. It is a tree up to about 20 metres (66 ft) tall, native to southern China, northeast India, Laos, northern Thailand, northern Myanmar and northern Vietnam.^[2]^[3] While the species is widespread, its populations are fragmented and it is threatened by cutting for timber as well as for using its bark and leaves for medicinal extracts.^[1]Sometimes (e.g. ^[2]^[3]) the species Cephalotaxus griffithii and Cephalotaxus hainanensis are considered synonyms of this species.

This Cephalotaxus sp. was shot in Naini Tal. It was a planted shrub/ small tree. Please suggest ID.

An inquiry (today) at the place of plantation (Naini Tal) suggest it as Cephalotaxus griffithii Hook.f. which seems correct to me. However, final word from expert is awaited.
