Abstract : Cyananthus Wallich ex Bentham, the only genus of Campanulaceae with superior ovary, is revised to clarify infrageneric relationships and phylogeny of the genus. Evidence obtained from the comparative gross morphology, anatomy, palynology, and karyomorphology recommends a new infrageneric classification of the genus, recognizing 23 species, belonging to two subgenera, four sections and four subsections. One subgenus(Subgen. Micranthus), one section(Sect. Suffruticulosi) and two subsections (Subsect. Flavi and Subsect. Lichiangenses) are described as new taxa. New combinations at sectional (Sect. Annui) and subsectional(Subsect. Stenolobi) ranks are also proposed. The genus Cyananthus is strictly distributed in the high mountains of China(Xizang, Yunnan and Sichuan), extending to Bhutan, Nepal and India(Kumaon-Garhwal, Assam and Sikkim), with altitudinal ranges from 2500～5300 m. It is observed that 13 species are endemic to SW China and only three species are endemic to the Himalayas (two species in Nepal and one to NW India). It is evident that Cyananthus is one of the most primitive genera of Campanulaceae and within the genus, subgenus Cyananthus (Sect. Stenolobi) is more primitive than the subgenus Micranthus. It is also suggested that SW China (most probably Yunnan) is the center of origin of Cyananthus, considering the occurrence of as many as 20 species of Cyananthus, representing several primitive taxa and many endemic species.

Phylogenetic and biogeographic analyses of the Sino-Himalayan endemic genus Cyananthus (Campanulaceae) and implications for the evolution of its sexual system by Zhuo Zhou, Deyuan Hong, Yang Niu, Guodong Li, Zelong Nie, Jun Wen, Hang Sun – Molecular Phylogenetics and Evolution (Impact Factor: 4.07). 05/2013-
ABSTRACT Cyananthus (Campanulaceae) is a small genus consisting of ca. 20 species endemic to the Sino-Himalayan region. Based on phylogenetic analysis using nuclear ribosomal ITS and four plastid markers (matK, rbcL, psbA-trnH and trnG-S), our results strongly support the monophyly of Cyananthus and its close relationship with the Codonopsis clade of the platycodonoids. Three major clades are supported, corresponding to the three sections of the genus, with sect. Cyananthus, which mainly occurs in the Himalayas, being a sister to the clade comprising the other two sections (sect. Stenolobi and sect. Annui) distributed primarily in the Hengduan Mountain region. We also observed that Cyananthus exhibits variation in its sexual system, possessing both hermaphroditic and gynodioecious species. Character evolution analyses using Mesquite suggest that gynodioecy evolved from hermaphroditism only once in sect. Stenolobi, but that there is a reversal in C. formosus. Molecular dating and biogeographic analysis with LAGRANGE support dispersal from the Himalayas to the Hengduan Mountains during the early evolution of Cyananthus. The extensive uplift of the Qinghai-Tibetan Plateau and the Hengduan Mountains played an important role in the subsequent diversification of the genus.

Cyananthus (Campanulaceae) : 1 post by 1 author.
I have updated eFI (efloraofindia) page on Cyananthus (Pl. click). Attempts have been made to incorporate most of the species available in India & nearby areas with details & keys directly or through links as far as possible. It’s quite possible that there may be some discrepancy in the accepted names & synonyms taken from other links. Species discussed so far in efloraofindia are given at the bottom of the page in the form of links against Subpages. On clicking them one can see all the details. If someone can provide complete list of Indian species with source references it will be wonderful. Any comments/ corrections are welcome. Updated all genera pages on Campanulaceae : 9 posts by 2 authors.

Pl. go through Cyananthus page (Campanulaceae) with images of species in efloraofindia (done by …). If you find any mis-identification, pl. let us know. If anybody can send images of other species of this genera (for incorporation in the website), it will be really nice. Also, if anybody is interested to take up the activity of inserting images on efloraofindia pages from efloraofindia posts, pl. let us know. |
