摘要
The large, yellow, bowl-shaped flowers of Opuntia lindheimeri, O. discata, O. phaeacantha major, and O. compressa in Texas are visited by various species of beetles and bees. The beetles and small bees (Perdita, Dialictus) are pollen thieves. The pollinators are the medium-sized and larger bees (Melissodes, Diadasia, Lithurge, Megachile, Agapostemon, etc.). Different species of the Opuntia lindheimeri group have the same pollination system and there is no evidence of any floral isolation between them. The pollination system of these species of Opuntia in Texas is essentially the same as that of Echinocereus fasciculatus and Ferocactus wislizeni in Arizona. © 1979 Springer-Verlag.
