A new species of Croton section Lamprocroton (Euphorbiaceae) from Southern Brazil
Croton longicarpus (Euphorbiaceae), a new species from southern Brazil, is here described and illustrated. The new species occurs in
open vegetation and at the edges of Araucaria forest. The analysis of herbarium collections and observations from populations in the field indicate
that the species has characters in commonwith members of Croton section Lamprocroton. The new species differs from other species in this section by
its unusually elongated ovary and fruit, the narrowly spatulate sepals of the pistillate flowers, and long inflorescences.Financial

Rediscovery and sectional placement of Croton ichthygaster (Euphorbiaceae), a rare species from Southern Brazil
Croton ichthygaster is a rare shrubby species from the states of Paraná and Santa Catarina in southern Brazil. We collected new specimens from a recently found population in Santa Catarina. This allowed us to record previously unknown morphological characters for the species and infer its sectional placement in the current Croton classification, namely sect. Adenophylli. We provide an emended description of C. ichthygaster and a key to distinguish it from morphologically similar Croton species occurring in its geographic range
