Description
The section is characterised by flowers in which the perianth is straight, at least at first; all four stamens are fertile; and the style end is narrow, and conical or cylindrical.[1]

Bentham listed several diagnostic characters for the species including the straight perianth-tube; the fertility of all four anthers; and the narrow style-end. At the time of publication it contained 12 species.[2]
Bentham did not specify a
