Unique pollen types in the caesalpinioideae (Leguminosae)

Abstract

In the legumes several pollen types were encountered during a survey of the Caesalpinioideae that were previously unknown or poorly known for the subfamily: Viscin threads (Jacqueshuberia), periporate pollen (Hardwickia, Coiophospermum), diporate pollen with a single continuous colpus (Duparquetia), tetracolporate pollen (Ceratonia), and pollen tetrads (Afzelia, Diptychandra). © 1980 Taylor and Francis Group, LLC.
