TL;DR: Based on molecular, morphological and cytological studies the previously monotypic genus Deinostigma W.T.Li has been expanded to include several species previously ascribed to Primulina Hance, including one previously placed in synonymy.
Abstract: Based on molecular, morphological and cytological studies the previously monotypic genus Deinostigma W.T.Wang & Z.Y.Li has been expanded to include several species previously ascribed to Primulina Hance. Deinostigma now comprises seven species, including one previously placed in synonymy. The new combinations Deinostigma cicatricosa (W.T.Wang) D.J.Middleton & Mich.Moller, Deinostigma cycnostyla (B.L.Burtt) D.J.Middleton & H.J.Atkins, Deinostigma cyrtocarpa (D.Fang & L.Zeng) Mich.Moller & H.J.Atkins, Deinostigma eberhardtii (Pellegr.) D.J.Middleton & H.J.Atkins, Deinostigma minutihamata (D.Wood) D.J.Middleton & H.J.Atkins and Deinostigma tamiana (B.L.Burtt) D.J.Middleton & H.J.Atkins are made. Deinostigma eberhardtii is lectotypified. The genus is defined by a combination of an alternate leaf arrangement, hooked hairs on many plant parts, flowers with the pedicel inserted at an angle and off-centre on the receptacle, and, where known, a somatic chromosome number (2n) of < 36. This new circumscription of the genus expands its distribution from Vietnam into South China.

TL;DR: In this article, the three genera Annonaceae, Artabotrys R.f. ex Kew Gawl. and Stelechocarpus Hook for the Malay Peninsula are presented.
Abstract: Notes concerning the three genera Alphonsea Hook.f. & Thomson, Artabotrys R.Br. ex Kew Gawl. and Stelechocarpus Hook.f. & Thomson (Annonaceae) for the Malay Peninsula are presented. Alphonsea kingii J.Sinclair is accepted as an endemic species and a second-stage lectotypification is presented for Alphonsea cylindrica King. Seven species of Artabotrys are lectotypified. The recently described genus Winitia Chaowasku is reduced to Stelechocarpus and a new combination is made for Winitia expansa Chaowasku.

TL;DR: The taxonomic history of Boesenbergia Kuntze (Zingiberaceae) in Myanmar is reviewed and eight species are currently confirmed as occurring in Myanmar, including two new records and a key to the species is provided with a description of each based on living material.
Abstract: The taxonomic history of Boesenbergia Kuntze (Zingiberaceae) in Myanmar is reviewed. Based on specimen records eight species are currently confirmed as occurring in Myanmar. These include two new records, Boesenbergia albomaculata S.Q.Tong and B. kerrii Mood, L.M.Prince & Triboun. Two previously listed species, Boesenbergia plicata (Ridl.) Holttum and B. thorelii (Gagnep.) Loes., are not considered here due to lack of specimens originating in Myanmar. A key to the species is provided with a description of each based on living material.

TL;DR: Hoya wallichii was previously considered to be endemic to Singapore but had become nationally extinct and consequently globally extinct, but this study reveals that it is also found in Peninsular Malaysia and Brunei and, even though it is still nationally extinct in Singapore, it is no longer globally extinct.
Abstract: After critical study of type material and all available collections, the identity of Hoya wallichii (Wight) C.M.Burton as a species distinct from Hoya campanulata Blume is clarified. Hoya wallichii was previously considered to be endemic to Singapore but had become nationally extinct and consequently globally extinct. This study reveals, however, that it is also found in Peninsular Malaysia and Brunei and, even though it is still nationally extinct in Singapore, it is no longer globally extinct. Hoya campanulata is widespread and locally common in Sundaland but also nationally extinct in Singapore. The two species are fully described and illustrated by line drawings and colour photographs. Two conservation assessments are made, three names are lectotypified, and one name is epitypifed. This paper exemplifies how critical taxonomic understanding is fundamental to meaningful conservation assessments.

TL;DR: Peninsular Malaysian Impatiens foxworthyi M.R.Hend.
Abstract: Peninsular Malaysian Impatiens foxworthyi M.R.Hend. is distinct from the Thai I. opinata Craib. Three new Impatiens species are described: I. glaricola Kiew with purple flowers, I. chikuensis Kiew with pale yellow flowers, and I. vinosa Kiew with deep red flowers. While Impatiens foxworthyi is widespread on karst limestone in Kelantan and Pahang, the three new species are narrowly endemic to Kelantan limestone and are critically endangered.

TL;DR: A new species, Polyalthia watui, is described from Brunei's Belait and Tutong districts and is very likely endemic to the Belait geosyncline that includes these areas.
Abstract: A new species, Polyalthia watui, is described. It resembles Polyalthia bullata King in having bullate leaves with a cordate base, but is distinguished by its flowers with shorter pedicels, longer sepals and petals, subsessile monocarps with long stiff erect hairs; and broad-obovate leaves with fewer pairs of secondary veins. The new species is only known from Brunei's Belait and Tutong districts and is very likely endemic to the Belait geosyncline that includes these areas.

TL;DR: The species Memecylon cerasiforme Kurz was previously known only from the type which was collected in Chittagong, Bangladesh, but a recent collection of the species from the Jaldapara National Park, West Bengal, India is the first record of its occurrence in India and the first flowering collection.
Abstract: The species Memecylon cerasiforme Kurz was previously known only from the type which was collected in Chittagong, Bangladesh. A recent collection of the species from the Jaldapara National Park, West Bengal, India is not only the first since the species was described in 1877 but also the first record of its occurrence in India and the first flowering collection. Its flowers can now be described and illustrated for the first time. An emended description, figure, phenological and habitat information, notes on related species, and a conservation assessment are also provided. The only original material available at Kew is designated here as a lectotype.
