TitlePollen morphology and evolution of the genus Harpullia (Sapindaceae—Harpullieae)
JournalBlumea - Biodiversity, Evolution and Biogeography of Plants
AbstractThe pollen morphology of 20 out of 26 species at present recognised in Harpullia is described. Laminations in the endexine and the presence of a mixed endexine-ectexine layer are demonstrated with TEM sections. Four pollen types, one of which can be subdivided into 8 subtypes, are distinguished and related to each other. The functional morphology and phylogeny of these types is compared with macromorphologic, ecologic and geographic evidence and expressed in a cladogram. The genus probably originated in East Gondwanaland and secondarily invaded Southeast Asia. Its position within Harpullieae is briefly discussed.
