Phylogenetics and development of Catasetum L.C. Rich. (Orchidaceae).
Flowers of the Neotropical orchid genus Catasetum exhibit an extreme sexual dimorphism, with pistillate and staminate flowers that are strikingly different in morphology and coloration. Staminate flowers of different species are also quite dissimilar. In contrast, pistillate flowers of different species are quite similar. Catasetum plants are monoecious, yet are thought of as functionally dioecious because a given individual will typically only produce either pistillate or staminate inflorescences in one flowering season (i.e., gender diphasy). Here, we present progress towards a molecular species level phylogeny of Catasetum, as well as developmental series of female and male Catasetum flowers.
