01012021 Although morphological features of Hoya flowers are well understood their function have only been studied in two species Hoya australis Forster 1992 and H. The morphology of the pollinating apparatus consisting of guide rails stamens pollinaria and stigmas of selected species of Hoya and of Dischidia as well as of Stephanotis floribunda and of Marsdenia cordifolia is examined and discussed in the light of the mechanisms involved in the pollination of their flowers. 9 Longitudinal section of annular corona.

Hoya Crassipetiolata originated from Vietnam. Angustifolia is indistinguishable from H. Carnosa Mochizuki et al 2017.
