Based on examination of specimens of Elatostema J. R. Forster & G. Forster (Urticaceae) from Vietnam, Elatostema albopilosum W.T. Wang var. vicinum L. D. Duan & Y. Lin, a new variety collected from Bac Can Province and Tuyen Quang Province, Vietnam, is described and photographed. This new variety has glabrous stems, glabrous leaves and glabrous peduncles which differs from var. albopilosum that having sparsely puberulent leaf blade on abaxial surface along veins and sparsely strigillose leaf blade on adaxial surface, and short pilose peduncles. E. integrifolium (D. Don) Wedd. and E. pseudodissectum W. T. Wang, two species previously known from Vietnamese adjacent countries, are newly recorded from Ninh Binh Province and Tam Dao National Park, Vietnam, respectively. The vouchers are kept in the Herbarium (PE) of Institute of Botany, Chinese Academy of Sciences, Beijing, China, and their descriptions and photographs are also provided.DOI: http://dx.doi.org/10.3329/bjpt.v21i1.19254Bangladesh J.

Impatiens pingxiangensis H. Y. Bi & S. X. Yu (Balsaminaceae), a new species from the limestone areas in Guangxi, China, is described and illustrated. The new species is similar to I. obesa in having succulent stems, subsessile peduncle, tufted pedicel and the lower petal in each pair of lateral united petals being connate, but differs from the latter by having perennial stems, leaf blades with 7–9 pairs of lateral veins, 1–2-flowered racemes, ovate inner lateral sepals, and elliptic capsule. Moreover, the pollen and seed coat characters also support the recognition of the new species.

Impatiens chashanensis H. Y. Bi & S. X. Yu (Balsaminaceae), a new species from the Sichuan Province in China, is described and illustrated. In comparison with the morphologically close I. dicentra, both species have succulent stems and the lobes of the lateral united petals end in a long hair, but I. chashanensis differs in having white flowers, four lateral sepals, lacerate apex of the inner sepal, shorter spur with swollen, slightly bifid apices. Moreover, leaf epidermal characters also support the recognition of the new species.

Three names of Carex Linnaeus (1753: 972) (Cyperaceae), namely Carex composita Boott (1858: 3), Carex myosurus Nees in Wight (1834: 122), Carex stramentitia Boott ex Boeckeler (1876: 351) are lectotypified as a part of the revision of Carex subg. Vigneastra (Tuckerman 1843: 10) Kükenthal (1899: 516) for the Flora of Pan-Himalaya.

In this study, one new species and one new variety are described and illustrated. Elatostema intanondense Q. Lin (Urticaceae), collected from Doi Intanond of Chiang Mai in Thailand, is morphologically similar to E. subincisum Weddell, but differs by having obscure stipules (vs. conspicuous , linear-lanceolate, 5-6 mm long in E. subincisum ), and elliptic to lanceolate nanophylls, 3-7 × 1.5-3.0 mm (vs. absent in E. subincisum ). Elatostema ranongense Yahara var. glabroum Q. Lin, a new variety collected from Khasi Hills in Mawhplong of Meghalaya, India. This new variety has glabrous stems and glabrous leaves that differs from var. ranongense that having densely hirtellous stems, densely strigillose leaf blade on abaxial surface along veins.
