Do Macropidia and Crescentia only produce flowers?
Macropidia Macropidia fuliginosa, the sole species of genus Macropidia, is a perennial rhizomatous flowering plant. Commonly known as the black kangaroo paw, it is endemic to Southwest Australia, specifically from Perth to Geraldton in the north of the region.
Platydesma Platydesma is a genus of plants in family Rutaceae. Evidence from 2009 indicates that "Platydesma" is nested within the related genus "Melicope" and is sister to all Hawaiian "Melicope" species. And while "Melicope" species are dioecious (individual plants only bear either male or female flowers), the flowers of "Platydesma" are hermaphroditic, suggesting a rare evolutionary reversion away from dioecy in "Platydesma". While they have no medicinal purposes; the board of water supply states that they can be used for a shrub.
