A New Species

Taxonomic studies in the genus Chamaecrista based on botanical collections from its endemic area, detailed analysis of our own collections and of herbaria, and in specialized literature enabled the discovery of a new species in the State of Tocantins, Brazil. The new species Chamaecrista pauciflora is herein described, illustrated, assigned to Chamaecrista sect. Absus subsect. Absus ser. Rigidulae and compared with C. azulana and C. filicifolia. The geographical distribution, conservation status, period of flowering and fruiting, morphological relationships, and environmental preferences of the new species are also provided. Additionally, a key to the species of Chamaecrista ser. Rigidulae occurring in Tocantins is presented.

A New Species

Taxonomic studies of Mimosa subser. Polycephalae revealed a new species and indicated the need for taxonomic and nomenclatural adjustments in the group. Mimosa pseudoracemosa is described and illustrated as a new species from Goiás State in central-western Brazil. We discuss its geographic distribution, environmental preferences, phenology and conservation status and compare it with the morphologically similar M. pseudoradula and M. flavocaesia. A new status for M. pseudoradula var. detonsa and a new name are proposed (= M. detonsa), including M. pseudoradula var. anapolitana and M. pseudoradula var. crystallites as its synonyms, as well an updated circumscription for M. pseudoradula without the admission of varieties. We also present descriptions, images, maps, comments on their distributions and morphological relationships, flowering and fruiting periods, and conservation statuses. In addition to the morphological and geographic discontinuities of the aforementioned taxa, their trichome micromorphology supported the establishment of the new species, as well as the taxonomic decisions involving M. pseudoradula.

Zanthoxylum unifoliolatum Groppo & Pirani (Rutaceae), a new species from northeastern Brazil is here described and illustrated. To date, this species is known from a small number of collections from the state of Sergipe and considered endangered, given its restricted geographical distribution and the rapid deforestation of the Brazilian Atlantic Rainforest. Z. unifoliolatum can be readily distinguished from other Brazilian Zanthoxylum by its unifoliolate leaves, rather than pinnate leaves present in other Brazilian species of the genus A detailed description and illustrations of this new species are provided, as well as comments on the geographic distribution, phenology, generic relationships and conservation status. Additionally, a key to the species of Zanthoxylum from Northeastern Region of Brazil is provided.

A New Species

Griffinia capixabae, a new species of Amaryllidaceae restricted to the mountainous region of the state of Espírito Santo, Brazil, and classified as endangered, is described and illustrated herein. It is morphologically similar to G. intermedia, but can be distinguished by its completely free spathe bracts, smaller overall perigone length, longer hypanthium, the lack of spots on the center of the sepals and petals, and smaller seeds. The new species is illustrated with photographs and a drawing; geographical distribution, habitat, phenology and conservation status are discussed. The paper also reassesses G. concinna as a valid species name, with a more detailed description and distribution including new records for the state of Espírito Santo. An identification key for the species with larger flowers and leaves of the genus is provided.

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).
