Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. E. J. Chandler 1966 | Stalked circular peltate seeds about 8 to 15 mm. in diameter with thick integuments enclosing in some cases cast of seed cavity of albuminous seed. Seed casts compressed at right angles to axis sometimes having a central depression connected with the margin on one side by a radial channel. Micropyle central ? Chalaza on lower surface contiguous with stalk. Hilar scar marginal indicated by truncation on cast. Few specimens showing narrow radial cavities instead of seed- casts (? anthers). Some of these have a stout central canal with fibre strands extending throughout their length. |
