- Diagnosis
- Seeds elongate ovoid, flattened, truncate and torn, with an aperture at one end and rounded at the other. 1 -35-1 -8 mm long and 0-9-1 -3 mm broad. Testa very thin, 60-80 pm in thickness, outer layer one cell deep, sclerotic, columnar in section, inner layer obscure. Surface cells oblong, regularly digitate, with four opposite pairs of lobes along their longer edges and one or two lobes on each shorter edge. The longer edges are orientated around the breadth of the seed and the cells are aligned in regular longitudinal and transverse rows. The lobes of the cells may themselves be indented. At the junctions of alternate longitudinal cell rows the tips of the lobes bear long or short, hollow, hairlike papillae.
