Abstract:

Dendroportulaca mirabilis U. Eggli, a Malagasy liana described as an atypical member of Portulacaceae, was shown by ndhF sequence data to be placed within Amaranthaceae tribe Celosieae, strongly supported as sister to Deeringia polysperma. A re-evaluation of the morphology of Dendroportulaca, including field observations, also supported its placement within Celosieae and in particular its relationship to the existing Malagasy species of Deeringia. Dendroportulaca mirabilis is herein transferred to Deeringia.
