“…As a consequence of these findings, the only practical solution to this taxonomy problem seems to be to place all segregate genera of the subtribe Strobilanthinae under an expanded, single and well-defined genus as Strobilanthes s.l. within the tribe Ruelliinae as proposed by Terao (1983) then followed by many authors (Scotland and Vollesen 2000;Tripp et al 2013;Souladeth et al 2017;Wood 2014;Augustine 2018;Deng 2019;Chen et al 2020;Wood and Scotland 2021;Wood et al 2022).…”

Abstract. Suratman, Suranto, Muzzazinah, Purnomo. 2022. Pollen morphological characters variation among species of Strobilanthes s.l. from Sumatra, Indonesia and its taxonomic implications. Biodiversitas 23: 4636-4648. The objective of this study was to evaluate pollen morphological characters variation and its taxonomic value among species of Strobilanthes s.l. from Sumatra. A total of 32 species from four genera previously recognized within the subtribe Strobilanthineae were used for pollen morphology observations using Light Microscope (LM) and Scanning Electron Microscope (SEM). A total of ten pollen morphological characters (both quantitative and qualitative) were observed in this study. In general, a great variation occurs in the majority of investigated pollen morphological characters. A similarity dendrogram among species of Strobilanthes s.l. based on pollen morphological character data revealed two major clusters. Cluster I consist of 25 species that differed from species in Cluster II in having pollen type I, pollen type II and pollen type III with a similarity coefficient of 0.61. Cluster II consists of seven species and has pollen type IV, pollen type V, pollen type VI and pollen type VII with a similarity coefficient of 0.46. An identification key to the species of Strobilanthes s.l. based on pollen morphology is also established for easy discrimination of the investigated taxa. This study revealed that pollen morphology was taxonomically useful character for identification and taxa delimitation of Strobilanthes s.l., especially at the species level. The results of this study also support earlier works through molecular studies, statistical analysis, gross morphology observations and leaf anatomy studies that all segregate genera of the subtribe Strobilanthinae should be merged under a single and well-defined genus as Strobilanthes s.l.

“…China has a vast territory with a wide range of complex and diverse topographies and soils and covering several climate types (Chen et al., 2020), which contribute to the high species diversity of Corydalis . The Himalaya‐Hengduan Mountains region is the diversity center of Corydalis (Wang, 2006).…”

A new species of Papaveraceae, Corydalis sunhangii, in the section Trachycarpae, is described and illustrated from Nyingchi City, Xizang, China. The new species has some resemblance to Corydalis kingdonis, but differs by radical leaves prominent, usually several, blade tripinnate (vs. insignificant, few, blade bi‐ to triternate); cauline leaf usually one, much smaller than radical leaves, usually situated in lower half of stem (vs. usually two, larger than radical leaves, concentrated in upper third of stem); racemes densely 13–35‐flowered (vs. rather lax, 4–11‐flowered); claw of lower petal shallowly saccate (vs. very prominently and deeply saccate); capsule oblong, with raised lines of dense papillae (vs. broadly obovoid, smooth). Phylogenetic analysis, based on 68 protein‐coding plastid genes of 49 samples, shows that C. sunhangii is not closely related to any hitherto described species, which is consistent with our morphological analysis.

“…Located on the Eurasian continent, China's vast territory, complex topography, and wide range of climate types have contributed to the wealth of Chinese botanical diversity (Sun et al 2017, Chen et al 2020). According to our latest statistics, in China, 24 Ceropegia species have been recorded, including 17 traditional Ceropegia species, two formerly included in Brachystelma , and four newly published species (Li et al1995, Wu et al 2019, Ma et al 2022a, b2022b, 2023).…”

Ceropegia sunhangiana P.R.Luo and T.Deng, a new species from Qiaojia, northeast Yunnan, southwest China, is described and illustrated herein based on its morphological characteristics and molecular evidence. This species is similar to C. christenseniana, and C. sinoerecta but can be distinguished easily by its stem, indumentum, leaf, and floral features, especially the corolla shape and size, the corolla tube and lobe characters. Phylogenetic analysis based on ITS, trnL‐trnF, trnS‐trnG, psbA‐trnH and rps16 sequences shows that this new species belongs to C. sect. Chionopegia H.Huber with strong support, which was mutually verified by morphology analyses. A table including the morphological characters of related species and a dichotomous key to all 25 species of Ceropegia in China are provided.
