Ceropegia suddeei sp. nov. (Apocynaceae, Asclepiadoideae) from northeastern Thailand

Abstract

Ceropegia suddeei Kidyoo is a new species discovered in the Phu Phan National Park, northeastern Thailand. Taxonomic description, illustrations of this new species and a comparison with the related species C. thailandica Meve. are presented.

Diversity of Diptera families that pollinate Ceropegia (Apocynaceae) trap flowers: An update in light of new data and phylogenetic analyses

“…New species are frequently described (e.g. Bruyns, 2003;Malpure et al, 2006;Dold, 2006;Meve 2009;Thulin, 2009;Sujanapal, 2013;Punekar et al, 2013;Kidyoo, 2014;Kidyoo & Paliyavuth 2017) and the full diversity of the (currently paraphyletic) genus may exceed 250 species. Regardless of taxonomy, the Ceropegieae is one of the largest monophyletic clades within the Asclepiadoideae.…”

Morphological and anatomical studies on some taxa of family Apocynaceae

“…Leaves shapes are ovate, obovate, oblong, linear, lanceolate or elliptic and their margin are entire or undulate with acute apex. The leaf is petiolate or sessile (Hutchinson 1973;Jafri 1966;Migahid and Hammouda 1974;El-Gazzar and Hamza 1980;Boulos, 2000;Kidyoo, 2014;Bibi et al, 2015). The cortex is consisting of hypodermal collenchyma of thick-walled followed by slightly thick-walled parenchyma (8-16 rows) containing cluster crystals of calcium oxalate.…”

Ceropegia laotica (Apocynaceae, Asclepiadoideae): the first new species of Ceropegia described from Laos

“…The latter species is found in Thailand in the Phu Wua Wildlife Sanctuary and Phu Langka National Park, c. 400 km northwest of the type locality of C. laotica. However, although Ceropegia digitiformis is also deciduous, the aerial stems survive the dry season because they are fleshy (Kidyoo & Paliyavuth, 2017), and not wiry as in C. laotica. Also the leaves are laminar, elliptic, ovate to rounded in Ceropegia digitiformis (and not rather linear and fleshy as in C. laotica) -displaying a close relationship to the Indian C. thwaitesii Hook.…”

“…Also the leaves are laminar, elliptic, ovate to rounded in Ceropegia digitiformis (and not rather linear and fleshy as in C. laotica) -displaying a close relationship to the Indian C. thwaitesii Hook. Kidyoo & Paliyavuth (2017) distinguish Ceropegia digitiformis from C. thwaitesii only on small deviations in corona morphology. In addition, Ceropegia digitiformis is unlikely to be a sister species of C. laotica because of the pollinarium morphology.…”

“…Myanmar has nine species, according to the last compilation by Kress et al (2003) and the inclusion of Ceropegia farrokhii McCann in C. kachinensis Prain by Singh et al (2015), and in Vietnam just three species are recorded (Costantin, 1912;Vietnam Plant Data Center: http://www.botanyvn.com). However, recent research on Ceropegia in Thailand has led to the discovery of numerous new species bringing the count for the country to ten (Kerr, 1951;Boonjaras & Thaithong, 2003;Meve, 2009;Kidyoo, 2014aKidyoo, , 2014bKidyoo, , 2015aKidyoo, , 2015bKidyoo & Paliyavuth, 2017). Finally, in Laos, only one unidentified Ceropegia species has so far been recorded (Newman et al, 2007).…”
