Studies in the Hypoxidaceae. II. Floral morphology and anatomy
The inflorescence and flowers of representatives of Spiloxene, Pauridia and Empodium were studied. The inflorescence shows a reduction from a several-flowered umbel to a single flower. The anthers are non-versatile in all three genera, unlike those of Hypoxis and Rhodohypoxis. In Spiloxene and Pa...

| description | The inflorescence and flowers of representatives of Spiloxene, Pauridia and Empodium were studied. The inflorescence shows a reduction from a several-flowered umbel to a single flower. The anthers are non-versatile in all three genera, unlike those of Hypoxis and Rhodohypoxis. In Spiloxene and Pauridia the ovary is 3-locular with axile placentation, while in Empodium it is unilocular with three parietal placentas. The floral vascular anatomy of the three genera is described and the generic differences pointed out. The close relationship between Spiloxene and Pauridia is demonstrated and the inclusion of Pauridia in the Hypoxidaceae is supported. Spiloxene is regarded as generically distinct from Hypoxis. |
