Abstract

Data on seed morphology of 132 species from 40 genera of all subfamilies (Ornithogaloideae, Hyacinthoideae, Urgineoideae, Oziroëoideae) of Hyacinthaceae are presented. So far, this is the most extensive study on the seed surface of Hyacinthaceae using scanning electron microscopy (SEM), and we also give insights into the systematic implications of seed surface micromorphology.

Abstract

As part of studies of seeds in Hyacinthaceae, we detected the genus Rhodocodon as a rare example in the family that shows remarkable variability in seed morphology. Detailed descriptions and a key for the seeds of 13 species and their systematic implications are presented.

Abstract

In the framework of a taxonomic revision of subfamily Urgineoideae based on morphological and genetic data covering numerous samples from its whole range of distribution, we here describe a new genus from Southern Africa. Iosanthus gen. nov. includes Ornithogalum toxicarium, a highly toxic species originally placed in subfamily Ornithogaloideae. However, our morphological studies support its inclusion in subfamily Urgineoideae based on the small bracts with a slight curve or short spur abaxially, the withered perigone circumscissile below and forming an apical cap and widely winged seeds with loose testa, a treatment also supported by its isolated phylogenetic position within this subfamily that facilitates the description of the new genus. Moreover, we also show that the holotype collection of this species represents a mixed collection of O. toxicarium in flower and an Albuca sp. in fruit, and therefore a lectotype is selected to maintain the current concept of this species.
