Aspidospermeae

Flowers and fruit of tear-shrub Vallesia antillana, from here.


Belongs within: Apocynaceae.

The Aspidospermeae are a tribe within the family Apocynaceae that was defined by Sennblad & Bremer (2002) as the most inclusive clade including Aspidosperma and Vallesia but not the Alyxieae, Carisseae, Hunterieae, Melodineae, Plumerieae, Tabernaemontaneae, Vinceae, Willughbieae or Apocynoidina. Members of this clade include herbs, shrubs and trees; some of the latter in the genera Aspidosperma and Alstonia are commercial timber sources.

Synapomorphies (from Sennblad & Bremer 2002): Style heads simple, lacking both stigmatic hollow and upper hair wreath; fruits apocarpous.
