Diagnosis
The long shoots bear several widely spaced alternate lateral racemose infructescences and one apical infructescence. The infructescences are 35—50 mm long and bear 5—7 follicles at distance of approximately 2—4 mm. A bud ring with swollen joint is visible where each raceme is attached to the long shoot. Spirally arranged follicles are borne singly on short side branches of the infructescences axis with a joint at the base of the stalk. Follicles are ellipsoidal or oblong, 10—16 mm long, 4—6 mm in diameter, with acute apex, attenuated into short stalk in the base. Mode of follicle dehiscence is unclear. Orientation of ventral sutures is different.
