Comments
A taxonomic revision of Elasis is currently being prepared (Pellegrini and Hunt, in prep.) and should address pending taxonomic problems in the genus. In gross flower morphology, Elasis can be confused with Tradescantia and most of its segregate genera (i.e. some species of Callisia, Gibasis, Matudanthus, Thyrsanthemum, Gibasoides, and Sauvallea). Nonetheless, Elasis can be easily differentiated from these genera due to its sessile inflorescence, with 1–several fasciculate, non-geniculate cincinni, pedicellate flowers, petals lacking tannin cells, inconspicuous connectives, and truncate stigma (Fig. 5, clade C; Fig. 6K–L).
