Abstract
Riina, R. & Berry, P.E. 2010. Two new South American species of Croton (Euphorbiaceae) and their phylogenetic affinities. Anales Jard. Bot. Madrid 67(1): 23-27. Two rarely collected species of Croton from South America are des cribed and illustrated. Croton chimboracensis P.E. Berry & Rii na is localized in western Andean Ecuador and is sister to Croton sect. Adenophyllum Griseb. Croton abonari Riina & P.E. Berry is known from a single location in Amazonian Brazil; it resembles both C. sampatik Mull. Arg. and members of Croton sect. Cuneati (G.L. Webster) Riina & P.E. Berry, but C. abonari can be easily distinguished from both groups by distinctive morphological characters.
Highlights
As a result of recent and ongoing taxonomic and phylogenetic studies on Croton, our understanding of this large genus has increased substantially, especially in the Neotropics, where several new species have recently been described by our network of collaborators (Secco & al., 2001, 2005; Riina & al., 2007; Steinmann & Martínez-Gordillo, 2007; Carneiro-Torres & al., in press; Caruzo & al., 2008; Cordeiro & al., 2008; Lima & Pirani, 2008; Medeiros & al., 2009; Van Ee & Berry, 2009; Riina & al., 2010a, 2010b), and several more are currently in preparation
These new findings will not substantially change the number of species in the megadiverse genus Croton, since other published names are being synonymized at roughly the same rate (Caruzo & Cordeiro, 2007; Lima & Pirani, 2008; Van Ee & Berry, 2009; Riina & al., 2010b; Carneiro-Torres & al., in press; Gomes & al., in press)
In this paper we describe two new species from South America that appear to be rare based on the few collections known to date, but are clearly distinct from any known species
Summary
As a result of recent and ongoing taxonomic and phylogenetic studies on Croton, our understanding of this large genus has increased substantially, especially in the Neotropics, where several new species have recently been described by our network of collaborators (Secco & al., 2001, 2005; Riina & al., 2007; Steinmann & Martínez-Gordillo, 2007; Carneiro-Torres & al., in press; Caruzo & al., 2008; Cordeiro & al., 2008; Lima & Pirani, 2008; Medeiros & al., 2009; Van Ee & Berry, 2009; Riina & al., 2010a, 2010b), and several more are currently in preparation. Croton chimboracensis P.E. Berry & Riina está localizada en los Andes occidentales de Ecuador y es hermana del clado de Croton sect. Croton abonari Riina & P.E. Berry se conoce de una sola localidad en la Amazonia de Brasil; es similar tanto a C. sampatik Müll.
