Systematics McGinty, Emma [1], Wright, Alexander [1], Roalson, Eric [1]. Morphological Variation in Andinocleome (Cleomaceae) and its Relationship to Species Concepts. Andinocleome (Cleomaceae) is a clade of ~11 species that is predominantly distributed in the Andes Mountains, but with a disjunct distribution into Central America. Here we present morphometric analyses on the Lechleri Group of Andinocleome (~8 species) to better understand the distribution of morphological variation in relation to current species concepts. A factorial analysis of mixed data (FAMD) was conducted on 161 specimens with a total of 35 quantitative and qualitative character traits measured. Geographic maps showcasing distribution and morphological overlap, a key to groups and species of Andinocleome, and botanical illustrations were created. We conclude that there are two morphologically distinct clusters each of Andinocleome anomala and A. lechleri; one with predominantly eglandular pubescence and the other predominantly glandular. Andinocleome longifolia and A. moritziana are morphological intertwined but geographically distinct. Andinocleome glandulosa is morphologically distinct based on its dense glandular pubescence, but its range overlaps with the glandular forms of A. anomala and A. lechleri. Lastly, Andinocleome magnifica is the most distinct species in the group, both in morphology and geographic distribution. These results suggest that hybridization and cryptic speciation may be contributing to diversification in the clade.
