Floral morphology and anatomy of Ophiocaryon, a paedomorphic genus of Sabiaceae
Ophiocaryon is a lesser-known genus in Sabiaceae, hitherto without detailed floral study and with unknown pollination mechanisms. Thaowetsuwan et al. examined floral morphology and anatomy revealing several unusual...
Geraniales flowers revisited: evolutionary trends in floral nectaries
Investigating floral morphology in the order Geraniales, Jeiter et al. present data to demonstrate that even the most disparate floral morphologies are derived from a common origin, sharing a basic pentamerous and...
Nectary evolution in Disa orchids
Independent nectary evolution of orchid genus Disa has involved both repeated recapitulation of secretory epidermis, and innovation of stomatal nectaries.
Floral characters in Capanemia
Capanemia, an orchid comprising seven species and mostly found in the Brazilian Atlantic rain forest, is divided into two sections based on leaf shape. Buzatto et al. examine floral morphology and anatomy and conclude...
