Fig. 8. Homalomena velutipedunculata S.Y.Wong, Y.C.Hoe & P.C.Boyce. A. Inflorescence at onset of pistillate anthesis, lower spathe artificially opened to reveal spadix. B. Detail of pistillate portion and interstice of spadix (spathe artificially removed) at onset of pistillate anthesis. C. Inflorescence at pistillate anthesis with mating pair of Parastasia beetles (Coleoptera: Rutelinae) on the spadix. D. Inflorescence at staminate anthesis. Note the pollen strands covering the staminate portion of the spadix. The beetle just visible behind the spadix is a chrysomelid, Chaloenus, scavenging pollen. E. Inflorescence at staminate anthesis, lower spathe artificially removed. Note that the interpistillar staminodes have been eaten and that that the pistillate zone is covered with beetle excrement.
