Ceropegia tribounii Kidyoo (Apocynaceae, Asclepiadoideae), a recently discovered, endangered species from western Thailand, is described as new. Comprehensive descriptions, illustrations, photographs, and diagnostic comparisons with morphologically similar species, such as C. anjanerica, are provided here. Ceropegia tribounii can be easily recognized by its sessile, linear leaves and its broadly obovate corolla lobes that are shorter than the corolla tube, as well as by its interstaminal corona with a pilose inner surface.

A New Species

We describe and illustrate Paepalanthus capixaba, a new species of Paepalanthus ser. Paepalanthus. The species is endemic to Espírito Santo state and restricted to a very distinct and endangered area, which comprises a mosaic of quartzitic sandy patches within a granitic argillaceous site. The indument of leaves, spathes, and scapes is crucial to recognize the taxon as a unique entity. The species is compared to Paepalanthus klotzschianus, the morphologically most similar species. An official conservation status of critically endangered species was assessed by the Centro Nacional de Conservação da Flora committee. Comments on the occurrence area and the morphological variation of the species, as well as a distribution map, photos, and illustrations are provided.

A New Species

A new species of Henckelia (Gesneriaceae) is here described and illustrated. It is morphologically most similar to H. oblongifolia but differs in having lanceolate calyx lobes, two prominent longitudinal flaps on the inner surface of the corolla tube, bilobed stigma and tomentose capsules. A detailed description of the new species with colour photographs, affinities and a comparison with related species is given. Based on the present data, the new species is provisionally assessed as Critically Endangered (CR) according to IUCN Red List Categories and Criteria.

Aristolochia luudamcui (Aristolochia subgen. Siphisia, Aristolochiaceae), a new species from Vietnam, previously misidentified as A. utriformis, is described and illustrated here. The new species is most similar to A. pseudoutriformis and A. utriformis concerning the morphology of the leaf lamina, the color of the perianth, and the shape of the limb, but A. luudamcui can be distinguished from the other two species by having a deeply 3-lobed limb and a glabrous, yellow inner surface of limb lobes. A detailed description, information on ecology, phenology, distribution, usage, a provisional assessment of the conservation status of the new species, and a comparison with morphologically similar species are provided as well.

Aristolochia annamensis, a new species from central Vietnam, is described and illustrated. This new species, belonging to Aristolochia subgenus Siphisia, is characterized by a truncate to slightly cordate leaf base, a strongly constricted, a straight, oblong, cylindrically-shaped upper tube without veins, 3–3.2 cm long, limb subcordate with margin of three lobes somewhat recurved, but not revolute, inner surface of limb smooth, annulus absent, throat densely covered with purple dots. In addition to the description, line drawings, ecology, conservation status as well as comparison with morphologically similar species are provided.

Ceropegia chuakulii is a new species from eastern Thailand. Illustrations, photographs and comparison of diagnostic characters to the morphologically similar species, C. acicularis Kidyoo are provided. These two species are characterized by erect stems, needle-like leaves, one–flowered sessile inflorescences and spathulate corolla lobes that are connate at tips. Ceropegia chuakulii is, however, clearly distinguished from C. acicularis by its ovoid to globose corolla tube, corolla lobes being as long as corolla tube, deeply bifid interstamial corona lobes with triangular-lanceolate segments. In addition, the analyses of quantitative morphological traits of flowers also strongly supported the distinctiveness of the new species.

Aristolochia vuquangensis (Aristolochia subgenus Siphisia), a new species from Central Vietnam, is described and illustrated here. This species is most similar to A. wardiana and A. forrestiana by sharing an ovate to lanceolate-ovate leaf blade and a cylindric or saccate-shaped limb, but it differs principally from the two species in having a densely brown hirsute outer surface of perianth, an oblong-ovate utricle, 1.1–1.5 cm long, an unequally semicircular 3-lobed limb in pre-anthesis, with a revolute median lobe, larger than two lateral lobes, abaxially concave, and lower one-third of the inner surface of limb densely covered by trichomes. A detailed description, illustrations, information on ecology, conservation status, and comparison with two similar species are also provided.

A new species of the Rhododendron (Ericaceae) in subgen. Tsutsusi sect. Tsutsusi from Puding county of Guizhou, China, is described and illustrated. The new species, R. pudingense X.Y. Dai, C.H. Yang & Y.P. Ma, is similar to R. myrsinifolium Ching ex Fang et M. Y. He and R. minutiflorum Hu, but it can be easily distinguished by its length and being pubescent on inner surface of corolla tube, sparse hairs below the middle of filament and the glabrous style.

A New Species

We present the description of Phrynus calypso sp. nov. from Trinidad and Tobago, and Venezuela This species is very similar to Phrynus pulchripes (Pocock), however after examining Colombian specimens of P. pulchripes (ca. type locality), many differences were found. Characters commonly used in diagnosis of Phrynus species are variable and make identification difficult. Differences in a few structures, like pedipalpal spines, could not be enough to provide a useful diagnosis.  It is necessary to account for variation of similar species in conjunction, and select non overlapping groups of characters. Observations in the variation in both species are presented, pointing out sources of confusion, and suggesting alternative characters to support diagnoses. At the moment, details about variation in many species in Phrynus, like that of P. pulchripes, are poorly known, and for this reason a redescription is provided.
