- Diagnosis
- The plant consists of a shoot bearing leaves at distinct
nodes. The leaf is simple, petiolate, and deeply trilobate with each
lobe further dissected. Leaves clustered at the nodes in threes or fours are
attached in a tight spiral at each node. Primary venation is basal
palinactinodromous. Secondary venation is pinnate, with secondary
vein branches bracing the leaf sinuses and then producing conspicuous
looping veins near the leaf margin. The long reproductive axis is axillary,
terminating in a flattened receptacle bearing five long, narrow, pseudosyncarpous carpels.
