A New Species

The new species Petrocosmea villosa D.J.Middleton from Shan State, Myanmar is described. It is most similar to Petrocosmea kerrii Craib, P. crinita (W.T.Wang) Z.J.Qiu and P. heterophylla B.L.Burtt in Petrocosmea sect. Deinanthera but differs particularly in inflorescence structure, inflorescence indumentum and in the long calyx lobes.

A New Species

Maesa brevipedicellata, a new species of Maesa ( Primulaceae-Maesoideae) from Papua New Guinea, is described and illustrated based on herbarium specimen observations. The collections of this species resemble M. rufovillosa and were previously determined as that species. Maesa brevipedicellata is unique with its self- supporting habit, hispid hairs throughout and paniculate inflorescences with very short pedicels. This new species mainly differs from M. rufovillosa by the habit (tree/shrub in M. brevipedicellata vs climber in M. rufovillosa) and the inflorescence structure (panicles in M. brevipedicellata vs simple racemes in M. rufovillosa).

A New Species

A new species of Amaranthus from Kerala (SW-India)—Amaranthus rajasekharii—is described and illustrated. Macro- and micro-morphological descriptions (with SEM analysis of pollen and seed), as well as original photos and drawings were provided. The new species is similar to A. dubius, from which it differs by stem color, inflorescence structure, gynoecium colour, number of stamens, and shape and lenght of tepals and bracts in pistillate flowers, seed ornamentation, and pollen architecture.

A New Species

A new species of Rubiaceae, Hedyotis kottangathattiensis M.B.Viswan. & U.Manik., is described from the Kalakkad-Mundanthurai Tiger Reserve in the Agastyamalai hills of the southwestern Ghats in South India. Hedyotis kottangathattiensis is allied to Hedyotis barberi (Gamble) Henry & Subram. but differs in its branching, leaf shape and colour, the presence of raphides, the colour and shape of the stipules, the inflorescence structure, calyx lobe shape, corolla lobe shape and colour, and capsule shape. A conservation status is proposed.

A New Species

Swertia hongquanii Jia X. Li, a new species of Gentianaceae, is described and illustrated from Mt. Wuling, southern China. It grows on the tops of steep limestone mountains surrounded by cliffs above an altitude of ca. 1400 m. This species resembles Swertia bimaculata, but differs from the latter by the stem leaf blades 2.0–4.5 × 1.0–2.5 cm, ovate to ovate-cordate, base cordate and subamplexicaul, the seeds irregularly polyhedral and the seed coats minutely thorny and reticulate. Based on morphological traits, i.e. the inflorescence structure and the number and structure of the nectaries, the new species may be a member of series Maculatae. A key to the species of series of section MaculataeOphelia is provided.

A New Species

A newPrimulinaspecies from Guangdong, China with an unusual inflorescence is described here.Primulina anisocymosais vegetatively most similar toP. bobaiensis. It can be distinguished from all species withinPrimulinamorphologically by its unique zigzag monochasial cyme and infructescence. To confirm the phylogenetic relationships and generic placement of this species, not only morphological anatomical features but also chromosome and DNA sequence data were examined and analysed here. Two samples from different populations identified asPrimulina anisocymosaare monophyletic and were nested in a monophyletic clade withinPrimulinawith high branch support. The somatic chromosome number of the new species is also reported (2n = 36), supporting its placement in the genus.

Dionysia splendens Alipour, Mehregan & Lidén, sp. nov., from Fars, Iran, is a unique species that cannot be easily accommodated in any hitherto recognised section of the genus and is immediately recognised by its large flowers and pectinate leaves with very broad pale and thick midvein. It agrees with Dionysia cespitosa Duby (Boiss.) in the small flat leaves, stalked inflorescence with large bracts, and few large ellipsoid seeds, but differs in the tubular calyx and large purplish-blue corolla. It is also somewhat reminiscent of Dionysia viva Lidén & Zetterl. in growth habit and inflorescence structure, but that species has large irregularly dentate leaves, yellow corolla and numerous small angular seeds. Dionysia splendens is so far known from a single locality with c.200 mature individuals. An updated key to Dionysia species in the Zagros mountains is provided.
