- Diagnosis
- Plant up to 27 cm in height, with a rhizome bearing lateral roots and shoots. Lateral fertile and main shoots in a pseudo-indeterminate pattern; reproductive branches on the main shoot in a cymose pattern. Each protogynous reproductive shoot with proximal dissected leaves, bract-like structures subtending a section (up to 2.5 cm long) of spirally arranged staminate clusters (each with 1–3 stamens), and the apex (only about l cm long) with spirally arranged solitary carpels. Stamens with a short filament (0.1–0.2 mm long), a linear dithecal and tetrasporangiate anther (5–7 mm long, 0.5 mm wide), and connective tip (1 mm long). Fully developed fruit up to 1.8 cm long, including a stipe (up to 3 mm long), carpel (1.4 cm long, 2 mm wide), and an apiculate tip (1.2 mm long). Fruits commonly with 5–8 orthotropous seeds (3 mm long and 1.3 mm wide) in one row attached on the abaxial side. Sometimes, the lowest carpellate stalk bisexual with two
carpels and one stamen.
