In this paper, Sedum xunvense is described as a new species from Zhejiang, Southeast China. Sedum xunvense is morphologically similar to S. formosanum, but the latter differs in clustered and robust stems (vs. solitary, slender), green or slightly red smooth stems and inflorescence rachises (vs. purple-red and ribbed), thick and succulent leaves (vs. thin), yellow anthers (vs. reddish-brown), erect follicles (vs. oblique), and is found in dry habitats in rock crevices (vs. damp ravines, rocks and mossy thickets). A reconstructed ML phylogeny of Sedum, based on nrITS sequence data, strongly suggests that S. xunvense forms an independent clade that is sister to a larger clade of many species, including S. formosanum.

In this paper, Sedum simingshanensesp. nov. is described as a new species based on morphological and molecular analyses, and its taxonomic relationships are discussed. Morphological analysis indicates S. simingshanense should be classified in the genus Sedum sect. Sedum and is distinct from the related species S. xunvense and S. formosanum in the morphology of its solitary, light green and smooth stems, flattened leaves, larger, obovate and spurless sepals, yellow anthers, 22–30 ovules per carpel, oblique follicles, and its habitat on shaded slopes or rocks. Phylogenetic analysis of sequences of the nuclear ribosomal internal transcribed spacer (ITS) also demonstrates that S. simingshanense has a highest similarity of only 97.22% with any known species and S. formosanum is the closest extant relative of the new species.

In this paper, Allium tianmuense is described as a new species based on morphological and molecular analyses, and its taxonomic relationships are discussed. It grows in the understorey of deciduous broad-leaved forests at 1000‒1500 m a.s.l. in Tianmu Mountain in Zhejiang (southeast China). Morphological analysis indicates A. tianmuense should be classified into A. sect. Sacculiferum and is distinct from the common species A. thunbergii and A. chinense in the morphology of leaves, umbel, filaments and phenology. Nuclear ribosomal DNA internal transcribed spacer (ITS) phylogenetic analysis further confirmed the inclusion of A. tianmuense within A. sect. Sacculiferum and revealed its distinction from all other species of this section representing a new species.

In this paper, Nanocnide simingshanensis is described as a new species based on morphological and molecular analyses, and its taxonomic relationships are discussed. The new species is currently known only from the Siming Mountain region of Yuyao County and the Yaolin National Forest Park of Tonglu County, both in Zhejiang Province, eastern China, where it grows in shrubs at an elevation of about 650 m under deciduous broad-leaved forests and at a limestone cave entrance. Morphological analysis strongly supports that N. simingshanensis should be classified into the genus Nanocnide. This species is distinguished from the related species N. pilosa and N. lobata by having long straight hirsute hairs perpendicular to the stem, petioles and peduncles, longer petioles, larger leaf blades, and female inflorescences developing on branchlets. It differs from N. zhejiangensis and N. japonica by having glomerulate male inflorescences shorter than leaves (vs. cymose inflorescences longer than leaves). Nuclear ribosomal DNA internal transcribed spacer (ITS) phylogenetic analysis demonstrates that N. pilosa and N. lobata are the closest extant relatives to the new species.
