description: 11. Ilex intricata Hooker (1875: 602). Type:—SIKKIM. Lachen, 3050–3350 m, May 29, 1849, J. D. Hooker s. n. (lectotype here designated: K); Lachen, 3350 m, May 29, 1849, Hooker s. n. (paratype: K [K000669510]); NEPAL. Yallung Mts, 3350 m, J. D. Hooker s. n. (paratype: K)   
 Ilex xizangensis Y.R. Li (1981: 353), syn. nov. Type:— CHINA. Tibet, Mêdog, 3200 m, 31. Jul. 1974, Qinghai-Xizang Exped. 74–3852 (holotype: KUN; isotype: PE).   
 Ilex xizangensis was described based on only one collection. The protologue states that it differs from I. intricata in being erect shrubs, having leaves narrow-elliptic, 2–3 cm long, 0.7–1 cm wide, and pedicel 5 mm long. Actually the field records of the type only state “shrub, 1 m ”, but without indication whether it is erect or prostrate. I measured leaves and pedicels of the holotype (KUN) and isotype (PE). Its leaves are 1.6–3.2 cm long, 0.8–1 cm wide, and the male pedicel is 4–5 mm long. I also measured these two parts in eight collections identified as I. intricata by Li and others from NW Yunnan and SE Tibet, with the result showing that leaves are 1.1–2.5 cm long, 0.8–1.2 cm wide. The most important is that the type is a male individual with a few flowers still in anthesis, which were found having welldeveloped stamens. However, Li (1981) misrecorded it as a “feminea” specimen and used “pedicelli 5 mm longi” for distinguishing her plant from I. intricata. Therefore, there are no distinct characters for recognizing I. xizangensis as a separate species.
