A New Species

Recent botanical expeditions to the Dolphin Head Mountains in western Jamaica allowed the collection of different specimens of a new species, Hohenbergia rohan-estyi, an enigmatic plant that resembles the also Jamaican-endemic H. negrilensis. In this study, we describe H. rohan-estyi and include notes on its geographical distribution, habitat, conservation status and taxonomy. The length of the stipes and number of flowers per spike permit the differentiation of H. rohan-estyi from H. negrilensis. In addition, the geographic distributions of these two species do not overlap, as H. rohan-estyi inhabits mountainous forests of the Dolphin Head region while H. negrilensis occurs in coastal areas of western Jamaica. Finally, H. rohan-estyi is the third species of Hohenbergia reported as endemic to the Dolphin Head Mountains, indicating the importance of this area in the evolution and conservation of the genus in Jamaica and the Caribbean.

Iucn Criteria

Epitypes are proposed for two species of Hechtia: H. subalata and H. jaliscana, both endemic to Western Mexico. The holotypes of both species consist of fruiting specimens. While the female flowers of both species are extremely similar, the staminate ones are noticeable different: we select staminate vouchers as epitypes to clearly circumscribe both taxa. As a result of the delimitation of the concept Hechtia subalata and its geographical distribution, we identify a new species from Durango, Mexico, previously misidentified as Hechtia subalata: Hechtia marthae. We provide images portraying plant parts of all species, as well as photographs in habitat. Finally, assessments of the conservation status of the three species sensu IUCN criteria are included.

A New Species

During the taxonomic treatment of Chamaecrista sect. Absus ser. Rigidulae as the object of the master’s dissertation of the first author, the analyses of our own collections and specimens from several Brazilian herbaria led us to establish a new species, Chamaecrista sparsifolia, and propose a new status and a new combination for Chamaecrista chaetostegia var. obolaria. The geographical distribution, phenology, conservation status, as well as images and illustrations of both taxa are given.

Abstract—A new species of Dichorisandra from the Brazilian Atlantic Forest is herein described, illustrated, and compared to morphologically similar species. Dichorisandra striatula is characterized by leaf blades with small and discontinuous white stripes on the adaxial surface, hirsutulous indumentum on both surfaces, obovate to broadly obovate petals, and ellipsoid fruits. Information on phenology, habitat, conservation status, and a geographical distribution map are also provided.

Stachys ahmet-savranii Doğu & Bağcı sp. nov. (Lamiaceae) from the Niğde (C5 Niğde, Turkey) is described and illustrated. It exhibits general features of the section Infrarosularis. It is closely related to Stachys citrina Boiss. & Heldr. but differs by its slender and unbranched stem; leaves structure; floral leaves equalling or longer than verticillasters; verticillester with 8 - 12 flowered and corolla 10 - 18 mm; Bracteoles reaching nearly middle of calyx tube. Diagnostic morphological characters are discussed. The geographical distribution of the new species is mapped. Notes are also presented on its ecology, biogeography and conservation status.

In this study, Fritillaria arsusiana (Liliaceae) is described and illustrated as a new species from Hatay province in southern Anatolia, Turkey. It is related to F. amana and F. hermonis by habitus features and broadly campanulate flowers, but differs mainly by its bulb shape and size, smaller leaf and flower features, and flower colour. It has also been morphologically compared with F. wendelboi, F. pinardii, and F. latakiensis. The detailed description, diagnostic characters, original photographs, geographical distribution, habitat and phenology, etymology, conservation status, and identification key of the new and the related species are presented in this study. IUCN conservation status of F. arsusiana is suggested as Critically Endangered (CR).
