A New Species

Here, we describe and illustrate a new alpine species of Astragalus sect. Anthylloidei from Iran. Astragalus wiesneri sp. nov., an interesting and rare species, is only known from the type locality in the Bul Mountain (near Eghlid city) in the southern Zagros Mountains. The new species is compared with close relatives, including A. nigrohirsutus and A. lalesarensis, which are also endemic to Iran. In addition, we assembled a dataset of nrDNA ITS sequences of 21 species (22 accessions) representing A. sect. Anthylloidei and ten species of other related spiny-cushion forming sections. Maximum likelihood methods and Bayesian Inference retrieved A. wiesneri sister to A. nigrohirsutus, a species growing in the same area as the new species. The description of A. wiesneri is presented along with a distribution map, some ecological information, field images, conservation status, and pertinent notes.

A New Species

Beaucarnea olsonii is described and illustrated from tropical deciduous forests of SW Puebla, Mexico. The new species can be distinguished from other Beaucarnea species by its massively swollen base that abruptly tapers into slender branches, by its conspicuously long stigma, and by its pedicel articulation that occurs at 2/3 of the length of the pedicel below the flower. With this new addition, the total number of endemic species of Beaucarnea for Mexico increases to 10, making this country the greatest center of diversification and endemism for the genus. We also provide a distribution map and a conservation status recommendation for the new species, as well as a key to the Beaucarnea species of southern central Mexico.

A New Species

A new species, Stachys semsurensis (sect. Infrarosularis), is described and illustrated from Adıyaman province, Turkey. From the morphological point of view, it appears to be similar to Stachys cataonica, but it differs in several morphological features including densely covered with short stalked to subsessile glandular hairs in flowering stems, verticillasters congested into ± globose head, calyx teeth lanceolate-subulate, corolla white, tube exserted and nutlets obovoid, greyish-brown, reticulate. A comprehensive description of the new species is provided, including detailed photographs, geographical distribution map, habitat structure and ecology, vernacular name and IUCN conservation status.

A new species, Strigula oleistrata, segregated from S. novae-zelandiae is described. The new species is widely sympatric with Strigula novae-zelandiae from which it is separated by a range of morphological characters and also by its nrDNA ITS sequence. As a result of this segregation, a new circumscription of S. novae-zelandiae is also provided. Comments on the ecology and conservation status of both species, and a revised key to the foliicolous Strigula species of New Zealand are provided.

A New Species

Based on fieldwork and an extensive analysis of herbarium and type collections, a new species which grows in sedimentary soil in the Brazilian semiarid region, Erythroxylum pyan (Erythroxylaceae), is described here. The new species occurs in areas of hyperxerophilic caatinga in the states of Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, and Bahia. Erythroxylym pyan resemble E. nummularium, but can be distinguished by having slender branches, foliar stipules non-striated longitudinally, 2-setulose at apex, leaf blades membranous to slightly chartaceous, emarginate to retuse at apex, inflorescences with 1 flower per node, long, slender and erect pedicels, and calyx lobes cuspidate at apex. Additionally, a distribution map and data about its phenology, conservation status, and uses are provide.

Mimosa schininii (Leguminosae), a new species from the Amambay region, in the Cerrado ecoregion of northeastern Paraguay, is described and illustrated. This new species belongs to Mimosa L. section Mimosa series Mimosa subseries Brevipedes Barneby, and is similar to M. brevipes Benth. and M. sceptrum Barneby, but differs from them by shorter inflorescence, secondary leaflets venation pattern and fruit dehiscence. This new entity resembles, in some characters, other subseries of series Mimosa, such as Mimosa section Mimosa series Mimosa subseries Pedunculosae (Benth.) Barneby and Hirsutae (Benth.) Barneby, but can be distinguished adequately from them by vegetative, floral, and carpological characters. Illustration, distribution map, and a key to distinguish M. schininii from close relatives are provided.

The Chimanimani Mountains, located at the Mozambique-Zimbabwe border, are geologically unique in that they consist of quartzites giving rise to peaks and outcrops between zones of schist supporting grasslands. The nutrient-poor quartzitic soils house a high number of endemic plant species. One of these is Sericanthe chimanimaniensis, which is here described as new for science. We give a detailed description and distribution map, illustrations, information on ecology and phenology, and an assessment on the conservation status. An identification key to closely allied species is presented.

Eremitis limae, a new species of Parianinae (Poaceae, Bambusoideae, Olyreae) endemic to the coastal forests of Bahia, Brazil, is described and illustrated. It is morphologically similar to species of Eremitis with characteristically narrow leaves: E. linearifolia, E. parviflora, and E. riodocensis. We discuss the morphological characters distinguishing the new species from its close relatives, and we also present illustrations, photos, and a distribution map. Eremitis limae is classified as Endangered (EN) according to the IUCN Red List categories and criteria.
