Abstract
A comprehensive analysis of seed coat micromorphology was performed with scanning electron microscopy on seeds of 24 of the 26 genera currently recognized in the family Cleomaceae. Micromorphological characters such as cell shape, shape and ornamentation of periclinal and anticlinal walls, epicuticular residues, hairs, and arils are presented. Analysis of seed coat characters show that they are a useful in differentiating lineages of the family. Some genera have highly specific characters with little variation and others have greater variability. Cleomaceae has undergone a systematic revision in the past decade producing a robust phylogenetic framework to interpret patterns of evolution. Results demonstrate that seed coat characters provide reliable support to the classification of genera in Cleomaceae and could inform evolutionary patterns in future studies.
