Diagnosis
The long shoots bear alternate short shoots 2—2,5 mm apart. Raceme infructescences located on short shoots in terminal position. Each raceme is 15—30 mm long, formed by 15—20 spirally arranged closely spaced follicles. The junction between the twig axis and short shoot is marked by a swollen joint. Short shoots bearing 3—5 alternate, closely spaced leaf scars. The follicles are borne on short stalks singly or sometimes in pairs. Follicles are ellipsoid in shape, small, 5—7 mm long, 2—3 mm in diameter, with acute or slightly attenuate apex and obtuse base attenuated in short stalk 0,5—1 mm long.
