A new species of Casearia Jacq. from Brazil

Abstract

A new species of Salicaceae growing in the state of Espírito Santo and in the south of the state of Bahia, Casearia valenciana R.Marquete & R.B.Torres, is described and illustrated here. It is similar to C. cotticensis Uittien, which grows further north in Amazonian Forest, by its pedunculate inflorescence, coriaceous leaves, and glabrous ovary. Yet, it differs from C. cotticensis by its shrub to small tree habit (vs. tree up to 27 m tall), smaller stipules, elliptic leaves (vs. lanceolate, broadly lanceolate, oblong-lanceolate), elongated anthers with longitudinal slits (vs. slightly deltoid, transversal slits), and larger fruits and seeds. Other diagnostic features of this new species include short-serrulate leaf border, and disc lobes fused with filaments at the base forming a small tube.

A new species of Casearia Jacq. (Salicaceae) from Central Panama and insights into its phylogenetic position within the genus

“…Nevertheless, the study showed nine monophyletic subclades. Recently, many new taxa have been described in the Neotropical regions from both South America ( Marquete and Mansano 2010 , 2013 ; Alford 2015 ; Marquete and Torres 2022 ) and Mesoamerica ( Castillo-Campos and Medina Abreo 2003 ; Linares and Angulo 2005 ). Here, we describe a new species of Casearia from Central America, endemic to Central Panama.…”
