A new phylogenetic tribal classification of the grape family (Vitaceae)

Vitaceae (the grape family) consist of 16 genera and ca. 950 species primarily distributed in tropical regions. The family is well‐known for the economic importance of grapes, and is also ecologically significant with many species as dominant climbers in tropical and temperate forests. Recent phylogenetic and phylogenomic analyses of sequence data from all three genomes have supported five major clades within Vitaceae: (i) the clade of Ampelopsis, Nekemias, Rhoicissus, and Clematicissus; (ii) the Cissus clade; (iii) the clade of Cayratia, Causonis, Cyphostemma, Pseudocayratia, Tetrastigma, and an undescribed genus “Afrocayratia”; (iv) the clade of Parthenocissus and Yua; and (v) the grape genus Vitis and its close tropical relatives Ampelocissus, Pterisanthes and Nothocissus, with Nothocissus and Pterisanthes nested within Ampelocissus. Based on the phylogenetic and morphological (mostly inflorescence, floral and seed characters) evidence, the new classification places the 950 species and 16 genera into five tribes: (i) tribe Ampelopsideae J.Wen & Z.L.Nie, trib. nov. (47 species in four genera; Ampelopsis, Nekemias, Rhoicissus and Clematicissus); (ii) tribe Cisseae Rchb. (300 species in one genus; Cissus); (iii) tribe Cayratieae J.Wen & L.M.Lu, trib. nov. (370 species in seven genera; Cayratia, Causonis, “Afrocayratia”, Pseudocayratia, Acareosperma, Cyphostemma and Tetrastigma); (iv) tribe Parthenocisseae J.Wen & Z.D.Chen, trib. nov. (ca. 16 spp. in two genera; Parthenocissus and Yua); and (v) tribe Viteae Dumort. (ca. 190 species in two genera; Ampelocissus and Vitis).     

Phylogeny and taxonomy of Afrocayratia,a new genus of Vitaceae from continental Africa and Madagascar

The genus Cayratia Juss. in the traditional sense (i.e., Cayratia s.l.) of the grape family has been shown to be non‐monophyletic. Previous studies supported the splitting of Cayratia s.l. into three genera, that is, Cayratia s.s., Causonis Raf., and a new genus representing the African Cayratia clade. However, the morphology of the African Cayratia clade has not been studied carefully and its phylogenetic position within Vitaceae remains unclear. Our study integrates molecular, distributional, and morphological data and supports the recognition of the new genus Afrocayratia from continental Africa and Madagascar. Phylogenetic analyses strongly support the monophyly of Afrocayratia and resolve it as a sister of Cayratia s.s. based on the chloroplast data, but it is placed sister to Cyphostemma based on the internal transcribed spacer dataset. Molecular dating suggests that Afrocayratia split with Cayratia s.s. during the Paleocene, but that the extant species of Afrocayratia did not diversify until the early Miocene. Afrocayratia differs from its allied genera in having short stigmas and seeds with subcircular ventral infold cavities in cross‐section. Three clades are detected within Afrocayratia, with A. debilis (Baker) J.Wen & L.M.Lu as the first diverged lineage. The second diverged lineage includes A. delicatula (Willems) J.Wen & Z.D.Chen and A. gracilis (Guill. & Perr.) J.Wen & Z.D.Chen. The third diverged lineage includes A. imerinensis (Baker) J.Wen & L.M.Lu, A. longiflora (Desc.) J.Wen & Rabarijaona, and A. triternata (Baker) J.Wen & Rabarijaona from Madagascar, which form a monophyletic group that diverged from the second lineage in the middle Miocene. Combining the morphological and molecular evidence, we formally describe the new genus Afrocayratia, make seven new combinations, and provide a key to species of the genus.     

Singchia and Gunnaria, two new genera of Orchidaceae

Singchia Z. J. Liu ＆ L. J. Chen, a new orchid genus, is established based on the new species S. malipoensis Z. J. Liu ＆ L. J. Chen found in southeast Yunnan, China. The new genus is related to Pteroceras, from which it differs by having a lip with its basal margins immovably adnate to the lower part of the pendent column foot, a thin-walled spur, and very unequally and deeply split pollinia, each with a distinct caudicle. In addition to a discussion on Ascocentrum pusillum, a species of questionable placement, another new genus, namely Gunnaria S. C. Chen ex Z. J. Liu ＆ L. J. Chen, is set up and a new combination, namely G. pusilla （Aver.） Z. J. Liu ＆ L. J. Chen, is made. The new genus Gunnaria differs from its allyAscocentrum by having a cross-shaped pollinarium, sulcate or split pollinia, each with a distinct caudicle attached to a common linear stipe much longer than either pollinia or viscidium, and strongly incurved side lobes of the lip.     

Ypsilorchis and Ypsilorchidinae,a new genus and a new subtribe of Orchidaceae

A new orchid genus, Ypsilorchis Z. J. Liu, S. C. Chen & L. J. Chen, is established based on Ypsilor-chis fissipetala (Finet) Z. J. Liu, S. C. Chen & L. J. Chen (basionym: Liparis fissipetala Finet). The new genus differs from Liparis and its allies by having two granular-waxy pollinia each with a somewhat elastic caudicle, deeply bilobed petals and strongly crisped-margined leaves with an apical awn to 1 mm long. These features are an indication of its distant relation to the members of the subtribe Liparidinae, and thus a new subtribe, Ypsilor-chidinae Z. J. Liu, S. C. Chen & L. J. Chen, is proposed.

Three new species in the genus Polygonum (Polygonaceae) from China

Three new species in Polygonum section Polygonum (Polygonaceae) from Xinjiang, China, are described and illustrated. Polygonum urumqiense F. Z. Li, Y. T. Hou & F. J. Lu is similar to P. aviculare L. in habit, but differs by having flowers densely clustered and spicate in the upper part of branches, stamens 5–6, and two types of achenes (the longer one densely and irregularly granulate on surface). Polygonum tachengense F. Z. Li, Y. T. Hou & F. J. Lu is similar to P. aviculare in the flowers not forming a raceme in the upper part of branches, the stamens 8, and the achenes striate-granulate on surface, but differs by the leaf blades linear-lanceolate, the midvein and lateral veins conspicuously raising abaxially, the ochreae longer, up to 1.1 cm, 15–20-veined, the flowers 3–6 clustered together in the upper axils of branches. This species is also similar to P. patulum M. Bieb. in the erect stem, and the flowers 3–6 clustered together in the axils of the upper part of branches, but differs by the midvein and lateral veins of leaves conspicuously raising abaxially, the ochreae longer, up to 1.1 cm, 15–20-veined, the leaves in the upper part of branches not becoming smaller gradually, and the flowers clustered in the upper axils of branches not forming a raceme, and the achenes striate-granulate on surface. Polygonum shiheziense F. Z. Li, Y. T. Hou & F. J. Lu is similar to P. argyrocoleon Steud. ex Kunze in the erect stem, the 3–6 flowers clustered in the upper axils of branches, the stamens 8, and the slightly smooth achenes, but differs by the midvein and lateral veins of leaves conspicuously raising abaxially, the ochreae longer, up to 1.1 cm, 15–20-veined, and the flowers clustered in the upper axils of branches not forming a raceme. This species is also similar to P. tachengense in habit, but differs in the leaves borne in the upper part of branches becoming smaller gradually and the smooth, slightly shiny achenes. The pollen morphology, leaf epidermal characters and achene micromorphology of the three new species and their relatives were comparatively observed under the scanning electron microscope (SEM).     

The Old World species of Pouzolzia (Urticaceae, tribus Boehmerieae). A taxonomic revision

The Old World species of the genus Pouzolzia have been revised and 24 species and 13 infraspecific taxa recognised. Worldwide, the genus now totals 36 species and 17 infraspecific taxa. Pouzolzia sect. Memorialis Bennett & Brown (including the genera Gonostegia Turcz. and Hyrtanandra Miq.) is maintained here as a section of Pouzolzia. The characters used to separate Pouzolzia from Boehmeria are found to work worldwide. In the Old World, the genus ranges, west to east, from Senegal to Japan and the Solomon Islands, and, north to south, from China, the Himalayas and Yemen to South Africa, Madagascar, Australia and the Lord Howe, Norfolk and Kermadec Is. Some species are common and occur almost throughout tropical Indomalesia or are widespread in Africa; others are rare and with a narrow range, for example restricted to one or a few oceanic islands. Each of the taxa occurring in the Old World is described and illustrated, habitats and geographical ranges are indicated, conservation status is discussed on the basis of our impression of old and new collecting activity, and distributions are mapped. The following new taxa are described: P. tsaratananensis Friis & Wilmot Dear from Madagascar, P. herpetophyton Friis & Wilmot‐Dear from the Comoro Is., and P. zeylanica subsp. calcicola Friis & Wilmot‐Dear and P. thailandica Friis & Wilmot‐Dear, both from southern Thailand. A new name, P. variifolia Friis & Wilmot‐Dear, is proposed for P. heterophylla (Blume) Wedd., nom. illeg. The following new combinations are published here: P. australis (Endl.) Friis & Wilmot‐Dear, P. sanguinea (Blume) Merr. var. formosana (Li) Friis & Wilmot‐Dear, P. sanguinea (Blume) Merrill var. cinerascens (Blume) Friis & Wilmot‐Dear, P. mixta Solms var. shirensis (Rendle) Friis & Wilmot‐Dear, P. hirta (Blume) Hasskarl var. parvifolia (Wight) Friis & Wilmot‐Dear, P. pentandra (Roxb.) Benn. & R. Br. subsp. wightii (Benn. & R. Br.) Friis & Wilmot‐Dear. and subsp. wightii (Benn. & R. Br.) Friis & Wilmot‐Dear var. gracilis (Miq.) Friis & Wilmot‐Dear. The following taxa are reduced to synonymy for the first time: Pouzolzia argenteonitida W.‐T. Wang, P. bracteosa Friis, P. calophylla W.‐T. Wang & C.‐J. Chen, P. guineensis Benth. var. seyrigii Leandri, P. guineensis Benth. var. madagascariensis Wedd., P. baronii Leandri, and P. auriculata Wight.
