In amplification of the original description it has to be noted that the (female) calyx lobes are definitely imbricate, not valvate, and that there is a disc divided into 6 glands below the ovary and the stamens also. The cataphylls of permanent branches are small, narrowly triangular, somewhat longer and narrower than the stipules. The leaflets are reniform, clasping the stem, 2-4 cm wide, 1-2 cm long about 14 of them on the deciduous branchlet. The embryo is slightly curved with circular cotyledons 2.6 mm long and the radicles about 0.7 mm long.
