Abstract
Piper hongheense (Piperaceae), a new species from Yunnan Province of China, is here described and illustrated. Morphologically it is similar to Piper boehmeriifolium and Piper boehmeriifolium var. glabricaule, from which it can be easily distinguished by the combination of characters: height 0.7–1 m, leaves oblong-lanceolate to lanceolate, 10–16 cm × 2.5–4 cm, infructescences ±0.6 cm in diam., berries and bracts white when mature. The description of the new species includes photographs, a detailed description, notes on etymology, distribution and habitat, as well as a comparison with morphologically similar species.

Piper hongheense W.J. Zhao, C.Y. Hao & N.H. Xia, sp. nov.
Erect subshrub, 0.7–1 m high, aromatic, dioecious. Stem greenish, terete, 3–4 mm in diameter, young branchlet sparsely puberulent, glabrescent, finely striate when dry, swollen at node. Leaf dimorphism present, prophyll 1–2 cm long. Sympodial leaf membranous to chartaceous, finely glandular, oblong-lanceolate to lanceolate, 10–16 cm × 2.5–4 cm, base subequilaterally truncate to oblique, one side rounded, the other tapered and acute; apex acutely acuminate to long acuminate, adaxially green and glabrous, abaxially pale greenish and sparsely puberulent on veins; petioles glabrous, 5–7 mm long; venation plinerved, veins 5–9, reticulate, uppermost distal pair of secondary veins alternate, arising 1–3 cm above base, reaching leaf apex, others basal. Monopodial leaf exhibits morphological similarities to sympodial leaf, with the primary distinction being that the base of monopodial leaf is predominantly ...
