Abstract

Given the taxonomic value of foliar indumentum within the Loasaceae family and the absence of detailed studies on this character in the genus Caiophora, this work examined the foliar indumentum of the 17 species occurring in Argentina. Conventional histological techniques were applied to process the samples, which were analyzed using light and scanning electron microscopy. The identified structures were classified into three categories: non-glandular trichomes (unicellular), glandular trichomes (multicellular), and emergences or stinging setae (multicellular). In turn, the non-glandular trichomes were classified into three types: scabrid, glochidiate and an intermediate form termed scabrid-glochidiate, some of which in turn have subtypes. The glandular trichomes are two- to four-celled and uniseriate with a globose head. Finally, emergences or stinging setae were classified into short or long according to their length. The hierarchical agglomerative clustering analysis indicated that the components of the foliar indument were not useful for establishing taxonomic groups within the genus Caiophora, however, their analysis provides valuable anatomical and micromorphological information that complements the description and understanding of the species inhabiting Argentina.
