Morphology Reproductive morphology Flowers
Flowers solitary, terminating short axillary shoots; pedicels 0·7–1·2 cm. long in fruit, articulated at the base.
Morphology Reproductive morphology Flowers Calyx
Sepals 4–5 mm. long in flower, elliptic, rounded, becoming brownish-red, 7–10 mm. long, flat and reflexed in fruit.
