Impatiens bijieensis X.X. Bai & L.Y. Ren, a new species from Northwest Guizhou, China, is here described and illustrated. This new species is distributed discontiguously in Jiulongshan of Dafang County and Dajiucaiping of Hezhang County, both of which belong to Wumeng mountains area, a karst plateau landform. It is morphologically similar to I. lasiophyton J.D. Hooker and I. leptocaulon J.D. Hooker in height, leaf blade shape and flower form, especially resembles I. lasiophyton in pilose plant. However, it differs in its deep purplish-red to rose-red flower, 2-lobed lower sepal apex and cylindrical capsule. A detailed description, color photographs, and a provisional IUCN red list assessment are provided, and its geographical distribution, ecology, and morphological relationship with relevant similar species are discussed.

Impatiens wutaishanensis R.L. Liao & Lei Cai, a new species from Southeast Yunnan, China, is here described and illustrated. This new species is most similar to Impatiens parvisepala S.X. Yu & Y.T. Hou in its racemose inflorescences, its four lateral sepals, the leaf arrangement, and in having yellow flowers. However, it differs in the height of the plants, the length of the petiole, the size and shape of the leaf blade, the shape of the spur, and the number of flowers in each inflorescence. A detailed description, color photographs, and a provisional IUCN red list assessment are provided, and its geographical distribution, ecology, and morphological relationship with relevant similar species are discussed.

Begonia leipingensis D. K. Tian, L. H. Yang & C. Li (2n = 30), a new species in Begonia sect. Coelocentrum from the limestone area of Guangxi, China. B. leipingensisis is easily distinguished from any other compound-leaved species in Begonia by its large variation in petiolule number and its unique spirally-arranged petiolule pattern, which has never been seen in Begoniaceae before and rarely seen even in other angiosperm taxa. Besides having non-overlapping flowering periods, it is clearly different from B. fangii, the most morphologically similar species in the same section and with the same chromosome number. In addition to its unique petiolule pattern, B. leipingensis has longer abaxial wings, shorter internodes, and usually larger leaves, leaflets and habit. Molecular phylogenetic analysis showed that B. leipingensis formed an independent lineage belonging to Sect. Coelocentrum. Morphological and phylogenetic evidence strongly supports this species as a new taxon in Sect. Coelocentrum of Begonia. B. leipingensis was assessed to be critically endangered based on criterion outlined by IUCN Red List Categories and Criteria.

Gravesia serratifolia, a new species from upper elevations of Marojejy National Park in northeastern Madagascar, is herein described, illustrated, mapped, and compared with similar species. It is readily characterized by its sparingly branched habit, leaf blades coarsely serrate with a moderate to sparse lepidote indumentum on both surfaces, inflorescence of few-flowered dichasia, calyx obsolete or evident as depressed truncate undulations with prominent calyx teeth that are laterally compressed when fresh, filaments with rusty-brown glandlike indumentum, and dorso-basal staminal appendages linear-oblong and widely spreading to coiled. A conservation assessment of Vulnerable is recommended for this species based on IUCN Red List Categories and Criteria.

Syzygium kuneneense, here described as a new species, is known only from the northern part of the Namib Desert in the Kaokoveld Centre of Endemism, southwestern Angola and adjacent northwestern Namibia. These rheophytic shrubs or small trees grow among rocks on the floodplain and banks of the lower Kunene River on the international boundary between Angola and Namibia. Diagnostic characters for Syzygium kuneneense include the oblanceolate or narrowly elliptic leaves, dense flower heads and the pedicellate flowers. A comparison of some of the more prominent morphological features to differentiate between S. kuneneense and the morphologically most similar species, S. guineense, is provided. Based on IUCN Red List categories and criteria, a conservation assessment of Vulnerable (VU D1) is recommended for the new species.
