Aconitum haridasanii, a new species from Tawang, India, is described and illustrated. This new species differs from its allied species Aconitum spicatum in having a taller and flexuous stem, pale yellow to whitish flowers in a shorter few-flowered inflorescence, densely pubescent shorter pedicels, bract shorter than pedicel, shorter sepals, longer petals, and only 3 carpels. Threat assessment was undertaken for the species following IUCN criteria (IUCN 2017 version 13) and the species was classified as Critically Endangered.

Behuria mestrealvarensis (Melastomataceae) from the state of Espírito Santo, Brazil, is described, illustrated and compared with B. capixaba, the species most similar to it. Behuria mestrealvarensis differs from B. capixaba by the glabrous petioles and hypanthia, by the solitary flowers or these in simple or compound triads up to 7 flowers, elliptic bracteoles almost the same size of the pedicel and hypanthium, sepals with eciliate margins and ovary apex with trichomes up to 0.5 mm. It occurs in a single locality, on an isolated, ca. 800m elev. inselberg. Due to its restricted occupancy area, fragmented landscape and poor habitat quality, this species must be considered as Critically Endangered according to IUCN criteria.

We describe here Begonia medeiroii, a narrow endemic species from the Atlantic Rainforest. The conservation status of this species was assessed as critically endangered according to IUCN criteria. This species resembles to B. catharinensis and B. hirtella in some characteristics, differing among other features due the presence of adventitious vegetative buds on the adaxial surface of the leaves.

A new species of Calliandra (Leguminosae, Mimosoideae, tribe Ingeae) from a restricted locality of Campeche, Mexico is herein described and illustrated. The species appears to be closely related to C. molinae, a species from Honduras, El Salvador and Nicaragua, from which it may be distinguished by being allopatric, and by a more limited development of suberose bark in stems and branches, comparatively smaller leaflets, consistently glabrous leaflets and corollas, and by the scarcely villous pods. Calliandra mayana appears to be restricted to an extremely small seasonally flooded savannah surrounded by tropical deciduous forest and, based on IUCN criteria, it is provisionally considered Critically endangered.

Primulina papillosa Z.B. Xin, W.C. Chou & F. Wen, a new species from limestone areas of Guangxi, China, is described and illustrated here. It morphologically resembles P. linearifolia (W.T. Wang) Yin Z. Wang and P. pseudolinearifolia W.B. Xu & K.F. Chung, but can be easily distinguished by some combined characters, especially its leaf blades densely papillose-hispid. We found only one population at the type locality with no more than 200 individuals, so that this new species is provisionally assessed as Critically Endangered (CR) using IUCN Criteria.

Described and illustrated is Warneckea albiflora R.D. Stone & N.P. Tenza, another localized endemic of coastal dry forest near Quiterajo in Mozambique’s Cabo Delgado Province. In Flora Zambesiaca the new species would key to Memecylon sansibaricum Taub. [≡Warneckea sansibarica (Taub.) Jacq.-Fél.], but is distinguished by its elliptic-lanceolate, attenuate–acuminate leaves and white flowers borne on pedicels 3.5–4 mm long (versus leaves elliptic and rounded to shortly and obtusely acuminate, pedicels 6–15 mm long, and flowers pale blue to deep blue in Warneckea  sansibarica). Because of its evidently very limited occurrence as well as on-going anthropogenic threats, Warneckea albiflora is provisionally assessed as Critically Endangered (CR) B1ab(iii) according to IUCN criteria. A key is provided to the Mozambican species of Warneckea.

Didymocarpus middletonii Souvann., Soulad. & Tagane, a new species of Gesneriaceae from Nam Kading National Protected Area, is described and illustrated. The new species is morphologically similar to Didymocarpus brevicalyx, D. formosus and D. puhoatensis but distinguished from the three by its fewer-flowered inflorescence, longer pedicel, and urceolate and multicellular eglandular hairy calyx. Based on the latest IUCN criteria, Didymocarpus middletonii is proposed to be Critically Endangered (CR). Our record of Didymocarpus represents a new genus record for the flora of Laos.

We propose that two populations previously referred to Hechtia epigyna, from the Mexican state of Hidalgo, represent a new species. Plants from the Hidalgo populations share the inferior ovary with Hechtia epigyna, an unusual trait in the genus, but they differ in their growth pattern (central vs. lateral inflorescence), characters of the adaxial foliar surface, petal color, and fruit position during dehiscence. We also provide a clarification on the typification of Hechtia epigyna. An assessment of the conservation status of the new species, Hechtia deceptrix following IUCN criteria resulted as CR (Critically Endangered).

Background and aims – The botanical exploration of Liberia, notably by C.C.H. Jongkind, has yielded several new species. One of his recent collections proved to contain a new species of Antidesma.Methods – Normal practices of herbarium taxonomy were applied to study the relevant herbarium material available at BR, K, and WAG. The relevant collecting data are stored at the Naturalis Biodiversity Center, Leiden, Section Botany. Map Maker was used to produce the distribution map.Key results – Antidesma jongkindii Breteler is described as a new species and illustrated. Its distinction from the other three species present in Liberia is presented in a key. The species is proposed to be listed as Critically Endangered [CR B2ab (ii)] following IUCN criteria.
