- Diagnosis
- The long shoots bear widely spaced alternate lateral racemose infructescences. The infructescences
are 50—100 mm long and bear 8—14 crowded follicles at distance of approximately 2—4 mm.
A distinct swollen joint is visible where each raceme is attached to the long shoot. The follicles are borne in
pairs or singly on short, longitudinally striated stalks 2—3 mm long. Side branches of the infructescences
axis are very short. Follicles are widely elliptical in outline, suborbicular in transverse section, 15—30 mm
long, 7—12 mm in diameter. The style is about 3 mm long, straight or slightly curved, reflexed. Fruits demonstrate
various stages of dehiscence from a short apical split to complete separation of valves.
