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.
