Typification.
Afzelius cited
Heringer
8029 as the type but as this is neither at S nor UB, it is possible the number was cited erroneously.
Heringer
8030 was cited as a paratype and is at UB, so is here designated as neotype.
Note.
This species is distinguished by its relatively slender habit, suborbicular leaves, persistent bracteoles and lanceolate sepals 12-16 mm long.
