A New Species

Mimosa is a very large genus with more than 540 species, which are distributed mainly in the Neotropics and are especially diverse in the Cerrado, where the genus shows high rates of endemism.         The Serra do Cabral mountain range, which is part of the Espinhaço mountain range, contains representative remnants of the Cerrado and is a very important area for the genus, where at least 20 taxa of Mimosa are reported. Unfortunately, it is a threatened and over-exploited region. Here we describe a new narrow endemic species from the Serra do Cabral, Mimosa osmarii, that shows affinities with M. paucifolia var. scoparia, a sympatric taxon. The conservation status of M. osmarii was assessed as vulnerable.

We describe here Begonia medeiroii, a narrow endemic species from the Atlantic Rainforest. The conservation status of this species was assessed as critically endangered according to IUCN criteria. This species resembles to B. catharinensis and B. hirtella in some characteristics, differing among other features due the presence of adventitious vegetative buds on the adaxial surface of the leaves.

Abstract—Baccharis funkiae, a new species endemic to Uruguay, is described and illustrated here. We also provide field work pictures, etymology, distribution and habitat, and preliminary conservation status information. Comments on how to differentiate it from the morphologically similar B. subopposita, highlighting differences setting the new species apart are discussed. Additionally, a key to the identification of the Uruguayan species belonging to Baccharis subgen. Baccharis sect. Cylindricae is presented.

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 of Senecio section Adamantina is here described as Senecio hortensiae (Senecioneae, Asteraceae), an endemic species from Parque Nacional dos Pontões Capixabas, Espírito Santo state, Brazil. This new species is recognised by the sessile leaves densely clustered at the median part of the stem and by the radiate capitula in a terminal lax panicle. It is closely related to Senecio graciellae but differs basically by the size and margins of the leaves, capitulescence and number of ray florets. Illustrations, comments, distribution map, and conservation status are provided for the new species. Additionally, a diagnostic key to the species of Senecio section Adamantina is provided.
