Critical examination of herbarium specimens and living plants has shown that Onosma mertensioides, O. tenuicaulis, O. zayuensis, O. xiangchengensis are conspecific with O. wardii, so the previous four names are here relegated to the synonymy of the latter.

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.

Taxonomic History

Habenaria Willd. (1805: 44) is represented by more than 35 species in the Pan-Himalaya (Chen & Cribb 2009, Pearce & Cribb 2002, Hooker 1890). As part of the ongoing revision work on the Pan-Himalayan Habenaria, some species of this species-rich genus are typified for nomenclatural clarity. Several species belonging to this genus have a long collection and taxonomic history and therefore pose difficulty in locating the original materials partly because either they were dispersed over various herbaria or were often catalogued under the disguise of different names. Through the critical examination of all the putative original materials—herbarium specimens and corresponding protologues, here we propose lectotypes of three species.

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.

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.

Critical examination of herbarium specimens (including type materials) has shown that Stranvaesia microphylla described from Vietnam is conspecific with Photinia davidiana var. undulata (≡Stranvaesia davidiana var. undulata), which is widely distributed in China. 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.

Critical examination of herbarium specimens and observations on living plants reveal that the syntypes of Dicliptera cyclostegia belong to Justicia sect. Harnieria and the three gatherings represent a different species each. A lectotype is designated here for the name Dicliptera cyclostegia and a new combination, Justicia cyclostegia is proposed. A detailed description, illustration and distribution map are also provided.

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 detailed study of taxonomic features of the Eriochilus dilatatus (Orchidaceae) complex (white bunny orchids) in Western Australia found that there were no consistent differences among most subspecies when herbarium specimens or living plants were compared. These subspecies were originally segregated primarily by differences in leaf size and shape and the number of flowers produced, but a critical examination of herbarium specimens found that these features were highly inconsistent within taxa. These features were also found to be highly variable over time and space within populations of living plants. The distribution patterns, habitat preferences and flowering times of these taxa were found to overlap, even for subspecies brevifolius and orientalis, which occupy the northern and eastern limits of the distribution of this species. Eriochilus dilatatus subsp. magnus and subsp. multiflorus were shown to be synonyms of subsp. dilatatus, whereas subsp. undulatus and subsp. orientalis are synonymised under subsp. brevifolius. As a result of this study, the two recognised subspecies are subsp. dilatatus and subsp. brevifolius, which can be readily separated by plant height, flower numbers and leaf morphology, except for a few intermediate plants where ranges overlap. New keys and descriptions to these taxa are provided. The reasons for previous taxonomic confusion in this group and in many other Western Australian orchids are discussed and research approaches to resolve these issues are suggested.
