多瓣含笑 meaning "multi-tepalled michelia"


CHINA. Yunnan Province: Xichou County, Fadou Mountain, in moist evergreen broad-leaved forest, 1300-1500 m, March 2003, R.Z. Zhou 0401 (holotype: IBSC n.v.). Same locality, July 2004, R.Z. Zhou & S.G. Jian 20040701 (paratype: IBSC n.v.).

Michelia macclurei   Dandy. In: Xia et al. (2008: 85), p.p. quoad syn. Michelia multitepala   R.Z. Zhou & S.G. Jian.

Michelia doltsopa   Buch.-Ham. ex DC. In: Sima and Lu (2009: 53) and Sima (2011: 196), both p.p. quoad syn. Michelia multitepala   R.Z. Zhou & S.G. Jian.

Note 1.

There is no data or images held at IBSC for the holotype (Huang Xiangxu, pers. comm., July 2019).

Note 2.

The authors of Michelia multitepala   noted that it closely resembles M. ingrata   B.L. Chen & S.C.Yang and M. macclurei   Dandy, but recorded in their comparative diagnosis sufficient morphological differences with these species to substantiate and name Michelia multitepala   as a distinct new species. M. multitepala   is recorded as a synonym of M. doltsopa   Buch.-Ham. ex DC. by the above noted authors. However, in Liu’s classification system of Magnoliaceae  ( Liu et al. 2004: 381), both M. macclurei   and M. ingrata   are placed in Michelia section Anisochlamys   Dandy while M. doltsopa   is placed in Michelia section Michelia   .

Note 3.

Michelia multitepala   is sufficiently distinct from M. doltsopa   ( Candolle 1818), to justify its species status, as shown by their known differentiating features compiled in Table 4 View Table 4 below. Additionally, M. multitepala   is known only to occur at 1300-1500 m on Fadou Mountain in the southeast of Yunnan Province, whereas M. doltsopa   occurs between 1500-2300 m throughout its widely dispersed geographical area from Yunnan to N Myanmar, NE India, Bhutan and SE Xiyang ( Liu et al. 2004: 242), or 2100-2500 m from central Nepal and Burma (Myanmar) to Sichuan and Yunnan ( Polunin and Stainton 1999: 19). As a consequence of the substantiation of its specific status, Michelia multitepala   is here transferred to Magnolia   in accordance with the past reduction of the remaining genera of subfamily Magnolioideae  to the genus Magnolia   .
