Morphology
3 Female plants are possibly monocarpous.
2 In male flowers, below each sinus between the corolla lobes, on the inner side of the receptacle-tube, are hard-fleshy, palish, glossy, verrucose, long-triangular markings, with at the apex, in each sinus, a minute globose creamy-white appendage, contrasting with the purple-red corolla. The meaning and morphological explanation of these structures is unknown.
1 Young plants have 4 verticillate, petioled pseudocotyledon-like first leaves, then sprawling, with leaves alternate, with long internodes; the margin of juvenile leaves is coarsely sinuate, the apex apiculate. Fresh leaves are somewhat fleshy, and glossy.
