Thalictrum bouffordii (Ranunculaceae), a new species from the Qionglai mountains region in western Sichuan, China, is illustrated and described. Morphologically T. bouffordii is most closely similar to T. xinningense in habit and having clavate filaments, apically recurved styles, and sessile, profoundly ribbed and pubescent achenes, but differs by having proximally glabrous (vs. densely pubescent) stem, inflorescence a many-flowered corymbiform compound monochasium (vs. a thyrse), abaxially pubescent (vs. glabrous) sepals, and purplish (vs. white) filaments.

Codonopsis atriplicifolia (Campanulaceae) from western Sichuan, China, is described here as a new species, which is similar to C. subscaposa in a number of characters. The results of molecular phylogenetic analysis of 25 species of Codonopsis based on chloroplast DNA fragments (matK, petD with petB-petD, rbcL) show that C. atriplicifolia is closely related to C. farreri. In morphology, the new species is distinctly different from the allied species by its linear-lanceolate leaves with subentire to pinnatipartite margins.

Solms-laubachia tianbaoshanensis, a new species from the scree slopes and alpine meadows of Hengduan Mountains of NW Yunnan, China, is described and illustrated. It resembles S. linearifolia and S. pulcherrima in gross morphology but differs in having crisped simple subhirsute trichomes to 2 mm long, persistent sepals, pink petals, and longer fruit. In addition, molecular phylogentic analyses based on sequences of nuclear ITS and chloroplast matK, petN-psbM, and trnL-F clearly showed that the new species is distinct from the other congeners.

Allium xinlongense from western Sichuan Province, China, is described as a new species. Its diagnostic morphological characters were confirmed to be valid by comparing them to those of related species, such as A. maowenense, A. chrysanthum, A. rude, A. xichuanense, A. chrysocephalum, and A. herderianum. Molecular phylogenetic analysis (combining ITS and rpL32-trnL markers) indicated that this new species is a member of Allium sect. Daghestanica. A comprehensive description of this new species is provided, including habitat environment and detailed morphological traits.

Tongoloa tagongensis (Apiaceae), is proposed as a new species from the Hengduan Mountains in Sichuan, western China. It is most similar to T. elata, but the new species’ roots are short conic to tuberous, lower leaves 2–3-ternate/pinnate, rays 4–11, and ribs more obvious. Description and illustrations are provided.

Sorbus gongshanensissp. nov., a new species from the Hengduan Mountains China, is described and illustrated. It is similar to S. kurzii from China (Yunnan & Xizang), Nepal, and Sikkim in the size of the leaflets, glabrous veins, persistent (sometimes) herbaceous stipules and reddish brown villous inflorescences and red fruits, but differs in its serrate leaflet margins toothed in the distal half or often almost to their base, reddish brown villous to glabrous hypanthium and reddish brown villous infructescences, among other characteristics.

The genus Elaphe is a highly diverse snake group with wide distribution in Eurasia. Here, based on morphological comparisons and molecular data, we describe a new species of this genus from western Sichuan, China. Bayesian inference and maximum-likelihood analyses of two mitochondrial DNA fragments (CO1 and 12S) showed that the new taxon differs from its congeners (CO1-based p-distance ≥ 4.1%). Morphologically and ecologically, the new species can be diagnosed from other species by a combination of the following characters: 1) medium body size, < 780 mm in total length; 2) midbody dorsal scales in 23 rows generally, not keeled; 3) ventrals 169–180 and subcaudal pairs 56–63; 4) first preocular docked with frontal; 5) internasal scales approximately trapezoidal; 6) length of gap between internasals more than 3/5 that between prefrontal; 7) length of tip of snout to frontal slightly larger than length of frontal; 8) ovoviviparous. Currently, the new species is known only from the Sichuan and Shaanxi provinces in China. This new species brings the total number of species in the genus Elaphe to 18.

Megarthrus chujiao Liu and Cuccodoro sp. nov., from Sichuan and Yunnan provinces in China is described and illustrated. It is the third record of the genus in the Hengduan Mountains, and the first endemic Megarthrus species from this temperate biodiversity hotspot. Megarthrus chujiao strongly resembles M. antennalis Cameron, 1941, from Nepal and North India, with which they form a new complex of species—the M. antennalis-complex within the predominantly Holactic and African M. depressus-supergroup of species.

A new species of the genus Lasianobia Hampson, 1905, Lasianobia nainysi Saldaitis, Volynkin & Zahiri, sp. nov. is described from highlands of western Sichuan Province of China. The new species is closely related to Lasianobia albilinea (Draudt, 1950). Adults, male and female genitalia as well as DNA barcode data of the new and related species are presented.

The Hengduan Mountains, as one important biodiversity hotspots in the world, is notable for its high habitat heterogeneity and extreme plant diversity which including many endemics species. Incarvillea uniflora, a new species is described from Hengduan Mountains. The new species is similar to I. himalayensis in having red corolla, stemless, solitary flower, capsule 4-angled and winged seeds, but differs by the characters of stable simple leaves, long triangular calyx lobes and solitary or clustered flowers. It is considered to be Data Deficient (DD) due to the lack of further field investigation.
