Rosa forrestiana var. maculata, a new variety of the genus Rosa from northwest Yunnan, China, is described and illustrated here. This new variety is primarily distinguished from the type variety, Rosa forrestiana var. forrestiana, by its purple spots at the petal base, a rare character in wild Rosa resources. We show the morphological features of this new variety with illustrations and photographs.

Leucoagaricus rosuliformis is described as a new species from the Changa Manga Forest, Punjab, Pakistan. This species can be separated from its close relatives, L. lahorensis and L. changamangaensis by its rosette-like central disc and with dense squamules becoming scattered towards margins. Molecular phylogenetic analyses using nuclear ribosomal DNA sequences from the internal transcribed spacer region also supported this taxon as a distinct species.

Peucedanum macilentum is a less-studied species endemic to China, previously assigned to the genus Kitagawia. To elucidate its taxonomic affinity, morphological and molecular analyses were conducted. Morphologically, Peucedanum macilentum resembles Ligusticopsis species in several diagnostic characters of the stem base clothed in fibrous sheaths, pinnate bracteoles, conspicuous calyx teeth, strongly dorsally compressed fruits, as well as more vittae on the commissure. Phylogenetic analyses of nrDNA ITS and plastome sequences further reveal that P. macilentum is distant from Kitagawia but nested within Ligusticopsis. Therefore, in the basis of the morphological and molecular evidences, Peucedanum macilentum is transferred into Ligusticopsis and a new combination, Ligusticopsis macilenta, is proposed.

Two new species of the genus Lacustriella from Lake Baikal have been studied by light and scanning electron microscopy. These are Lacustriella concinna and L. provecta, both of which have a unique combination of characters. We document morphological differences between new species and similar Lacustriella taxa; the lacking details on the ultrastructure of the closely related Lacustriella acutocuneata, were supplemented with our own SEM data and used for comparison. Most of the world’s Lacustriella species are currently found in the lake.

Oreocharis hapii, a new species endemic to Quang Nam Province in central Vietnam, is described and illustrated here. This species bears a superficial resemblance to O. cotinifolia in its elliptic leaves, campanulate corolla tube, and the stamens protruding from the tube. However, the new species differs in its stoloniferous habit (vs. absent stolons), petioles and stems densely woolly (vs. villous), leaf blade adaxially scabrous (vs. villous), sub-actinomorphic corolla (vs. distinctly zygomorphic) that is white (vs. pink) with 4 stamens (vs. 2). Following IUCN criteria, the conservation status of the new speciesis proposed to be Vulnerable (VU: D1).

A new species Campanula densiciliata from Yamunotri, Uttarakhand is described and illustrated. The new species is closely related with other previously described species namely, Campanula argyrotricha and C. latifolia but, differ in its rounded leaf base with sinuate margins, much reduced calyx teeth less than half of the corolla with crenate margin, elliptic corolla lobes and different lengths of stigmatic lobes. The new species is found in humus rich soil under Rhododendron forest.
本文描述了来自北阿坎德邦亚穆诺特里的一个新种 Campanula densiciliata，并绘制了插图。新种与之前描述的其他物种（即 Campanula argyrotricha 和 C. latifolia）密切相关，但其不同之处在于叶基部圆形，边缘具深波状突起，萼齿大大减少，花冠的一半以下具圆齿边缘，花冠裂片为椭圆形，柱头裂片的长度不同。新种发现于杜鹃林下富含腐殖质的土壤中。

Based on literature consultation, specimen survey, and observations of living plants in the wild, we demonstrate that Clematis sinii and C. xinhuiensis (Ranunculaceae), respectively described from Guangxi and Guangdong of China, are not essentially different from C. meyeniana in any characters, a species widely distributed in eastern and southeastern Asia and morphologically highly variable. We therefore place both C. sinii and C. xinhuiensis in synonymy with C. meyeniana herein. Pollen morphology is not useful for distinguishing between C. meyeniana and its closely similar species. We also point out that further work is needed to thoroughly clear up much of the taxonomic confusion involving C. meyeniana and its morphologically similar taxa.
根据文献查阅、标本调查和野外活体植物观察，我们证明了分别描述于中国广西和广东的 C. sinii 和 C. xinhuiensis（毛茛科）与 C. meyeniana 在任何特征上都没有本质区别，C. meyeniana 是广泛分布于亚洲东部和东南部的一个物种，形态上变化很大。因此，我们将 C. sinii 和 C. xinhuiensis 与 C. meyeniana 并列。花粉形态学对于区分 C. meyeniana 及其近似种并无帮助。我们还指出，要彻底清除涉及 C. meyeniana 及其形态相似类群的分类混乱，还需要进一步的工作。
