A new combination in Cremanthodium (Asteraceae, Senecioneae) from Sichuan, China

Critical examination of herbarium specimens (including type material) of Cremanthodium ellisii var. roseum (Asteraceae, Senecioneae) has shown that the variety should be transferred to C. brunneopilosum. We therefore propose a new combination, C. brunneopilosum var. roseum.

Senecio pentanthus (Asteraceae, Senecioneae) has been previously placed in synonymy with Synotis triligulata. Our critical examination of herbarium specimens (including type material) and living plants of S. pentanthus demonstrates that it can be easily distinguished from Syn. triligulata by the leaf serration and the number of phyllaries and florets. We therefore reinstate the independent specific status of S. pentanthus and propose a new combination, i.e. Syn. pentantha. Lectotypification is made for Syn. pentantha herein. A key to all the known species in Syn. ser. Microglossae and Syn. vagans, a species placed in Syn. ser. Erectae but actually more closely similar to those in the former series, is provided.

A New Species

Cremanthodium atrocapitatum (Asteraceae, Senecioneae) has been previously largely misunderstood, resulting in considerable taxonomic confusion involving several taxa. Based on observations of both herbarium specimens (including type material) and living plants, here we clarify the taxonomic identity of this species. The Xizang (Tibet) plants previously referred to C. atrocapitatum are described as a new species, i.e. C. bomiense. Cremanthodium campanulatum var. brachytrichum is found to be very close to C. atrocapitatum rather than C. campanulatum, and is thus treated as C. atrocapitatum var. brachytrichum.

Thalictrum semiscandens (Ranunculaceae) was described from Lushui County in northwestern Yunnan, China and has been almost totally overlooked since its publication. Based on a critical examination on herbarium specimens (including type material), we demonstrate that it is conspecific with T. trichopus, a species widely distributed in southwestern China (Sichuan and Yunnan). We therefore reduce T. semiscandens to the synonymy of T. trichopus herein. Lectotypification is proposed for T. trichopus.

Based on critical examination of herbarium specimens (including type material), we demonstrate that Clematis hainanensis (Ranunculaceae), described from Hainan in southern China, is not essentially different from C. leschenaultiana, a species widely distributed in China (Chongqing, Fujian, Guangdong, Guangxi, Guizhou, Hainan, Hubei, Hunan, Jiangxi, Sichuan, Taiwan, Yunnan), and also in Indonesia, the Philippines, and Vietnam. We therefore place C. hainanensis in synonymy with C. leschenaultiana herein. Lectotypification is proposed for C. leschenaultiana var. denticulata, which was described also from Hainan and treated as a synonym of C. leschenaultiana. The placement of the name C. splendens is briefly discussed.

Therefore, S. microphylla is reduced as a synonymy of P. davidiana var. undulata. Additionally, one new combination has been proposed and one lectotype has been designated here.

Alpinia laosensis was previously placed in synonymy under A. conchigera. However, a critical examination of herbarium specimens (including type material) and living plants of A. laosensis and A. conchigera reveals that they are two separate species. Alpinia laosensis can be distinguished from A. conchigera by the shape of its fruits, shape and size of leaves and colour of labellum. We therefore reinstate A. laosensis as an independent species. A detailed description of A. laosensis together with a distribution map of both species are provided.

Taxonomic Studies

Costus chinensis and C. oblongus (Costaceae) has been previously placed in synonymy under C. lacerus. Our critical examination of herbarium specimens including type material demonstrates that they are morphologically distinct from each other. Therefore, the independent specific status of C. chinensis and C. oblongus is reinstated. According to recent studies, Costus chinensis as well as other two Chinese species, C. oblongus and C. viridis, should be transferred to Hellenia. Thus, a new name for C. chinensis, and two new combinations are proposed. A detailed description of C. chinensis along with a distribution map of three allied species is also provided.
