Gypsophila guvengorkii (Caryophyllaceae) is described as a new species from Karabük province, Turkey. Morphology, distribution in Turkey, notes on ecology, and the conservation status are provided, as well as a comparison with the similar species G. brachypetala, G. briquetiana, and G. davisii. Additionally, an emended description of G. brachypetala is given. G. patrinii is excluded from the Flora of Turkey since the specimens collected from Doğubayazıt, which were previously identified as G. patrinii, actually refer to G. transcaucasica, which represents a new record for Turkey.

A New Species

Background and Aims: Aristolochia is the largest genus in Aristolochiaceae and is widely distributed in the world. A recent synopsis of Aristolochia in Costa Rica recognized 19 species; nevertheless, recent botanical exploration in southwestern Costa Rica has revealed yet another new species of this genus. Methods: The new species resulted from fieldwork in Buenos Aires, Puntarenas Province. Specimens from several herbaria were examined, as well as the type material of the most morphologically similar species. Comments about its distribution, habitat, phenology, conservation status and morphological distinction from related species are provided.Key results: Aristolochia quiricoana, a member of Aristolochia series Thyrsicae, is described and illustrated from the southern Pacific region of Costa Rica, where it is apparently endemic. It is similar to A. ornithorhyncha, from which it is distinguished by its shorter pedicels, wider, oblong perigone limbs with a shorter appendix, and a different floral color pattern.Conclusions: The new taxon described here represents the 22nd species documented in Aristolochia series Thyrsicae, as well as the 20th species of the genus from Costa Rica.

A New Species

Background and aims – The genus Anemopaegma (Bignoniaceae) includes around 47 species and has its centre of diversity in Brazil. Here, we describe and illustrate a new species from French Guiana, Anemopaegma kawense, and compare it to the two most similar species, A. foetidum and A. granvillei. We further assess the conservation status of all three species.Material and methods – Morphological descriptions are based on herbarium specimens deposited at BM, BR, CAY, INPA, K, MO, P, SPF, and U, and, in the case of the newly described species, also on field observations. The conservation status assessments follow the IUCN Red List criteria.Key results – Anemopaegma kawense differs from both A. foetidum and A. granvillei by its densely villose twigs, longitudinally plicate leaflets with secondary veins not or hardly prominent below, and tertiary veins impressed below. It is further separated from A. foetidum by the leaflets that are villose below and the calyx that is entirely pubescent outside. On the other hand, A. kawense differs from A. granvillei by the densely lepidote outer surface of the corolla, shorter petiolules, leaflets with midrib impressed above, shorter bracts and bracteoles, inflorescence peduncle exceeding the rachis, and pedicels densely puberulous, not lepidote or only sparsely so at the apex. This species is endemic to the Kaw Mountain in north-eastern French Guiana, where it grows in low stunted forest on laterite; it is assessed as Endangered according to the IUCN criteria. New descriptions are provided for A. granvillei, which is newly reported from Suriname, and for A. foetidum, which is newly reported from French Guiana; these two species are assessed as Endangered and Least Concern, respectively. Lectotypes are designated for A. maguirei, which is here synonymised with A. foetidum, and for A. umbellatum, another synonym of that species. A key to the 12 species of Anemopaegma occurring in the Guianas is presented.

A New Species

Astragalus dinawarii Bidarlord & F. Ghahrem. (Fabaceae) is described as a new species based on material collected on the Talesh Mountains, northwestern Iran. This species belongs to a large bifurcating section, Astragalus L. sect. Incani DC. Morphologically, it is close to A. bukanensis Maassoumi & Podlech, A. diversus Podlech & Maassoumi, and A. dilutuloides Maassoumi, F. Ghahrem. & Bagheri, sharing several densely hairy leaflets and stipitate legumes. This species is easily distinguished from similar species by a set of both vegetative and reproductive characters such as size, shape, number of leaflets, shorter calyx, and longer legume stipe. A detailed description and comparisons with similar taxa, color images, distribution and habitat, and conservation status of the new species are provided.

Hysterionica s.l. (including Neja) comprises ca. 15 species distributed mainly in the grasslands of southern Brazil, Uruguay, central and northern Argentina and Southern Paraguay. Based on field surveys, study of nomenclatural types and other specimens, and review of literature, a new species is proposed here, Hysterionica chamomilloides, endemic of mountainous regions of northern Uruguay, and southwestern Rio Grande do Sul state, Brazil. This work provides a detailed morphological description of the new species, information on its geographic distribution, habitat, phenology, conservation status, and discusses the main differences between H. chamomilloides and the morphologically most similar species. Illustrations, images and a key to the South American species of Hysterionica are also supplied.

Veronica ersin-yucelii (subg. Pentasepalae, Plantaginaceae) is described and illustrated as a new species. It grows on marble rocks and screes, in one single site in Central Anatolia (Eskişehir Province), at elevations from about 1700 to 1820 metres above sea level. Diagnostic features are also given to enable comparison with the most similar species, V. caespitosa Boiss. and V. multifida L., especially regarding the indumentum, habit, inflorescence, bracts, seeds and leaves. The geographical distribution of the new species is mapped. Notes about its ecology and conservation status are also presented.

We here describe and illustrate Begonia tadungensis (B. sect. Platycentrum), a new species from southern Vietnam. The new species is most similar to B. albopunctata in having broadly ovate leaves, three free styles, 4-loculed ovary, and berry-like fruits with a beaked apex, but differs mainly in having a glabrous abaxial leaf surface (not densely red pubescent), and fruits with gray puberlous hairs (not white papillose). It is also similar to B. pendens in its broadly ovate leaves and monoecious breeding system, but differs in having 6 tepals in the pistillate flowers (not 5) and 4-loculed ovaries (not 3-loculed). Information on ecology, conservation status, and a further comparison of characters with these two similar species is also provided.

Pouteria kossmanniae (Sapotaceae, Chrysophylloideae), a new species from Central Amazonia, is here described. It is known from the Manaus region, Amazonas, Brazil, and is found in non-flooded upland forests, known as terra firme. Illustrations are provided in addition to geographic distribution, with a comparison of the morphological and spectral (near-infrared) differences between P. kossmanniae and its very similar species Pouteria macrophylla, Pouteria manaosensis, and Pouteria rodriguesiana. The species is naturally common in some urban forest fragments, but since only a low number of subpopulations is known, we assign P. kossmanniae the preliminary conservation status of “Endangered”.

A New Species

Peliosanthes oksanae is described and illustrated as a new species from eastern Thailand. It is most similar to P. gracilipes known from northern and southwestern Thailand and northwestern Laos, from which it differs mainly by the shorter flowering stem, flowers borne singly or binately in the axils of the bracts and almost free oblong filaments not forming a typical corona. We briefly discuss taxonomic relationships between P. oksanae and two similar species, P. gracilipes and P. caesia. It is notable that especially P. oksanae and P. gracilipes are close in floral characters to Ophiopogon. We also report P. triandra, which was described from southern Cambodia, as new to Thailand. Both P. triandra and P. oksanae occurred in the same habitat.
