Inflorescence with (2-) 10-30 flowers, somewhat lax in flower, lax in fruit. Bracts 2.5-6 mm, ovate, acute, usually magenta-tinged. Pedice1s 5-9 mm in flower and fruit, free.

Seeds 0.5-0.7 mm, reniform to pyriform, transversely ridged, dark grey to black; transverse ridges 7-10, obtuse to subacute, discrete or rare1y anastomosed; periclinal wall of testa-cells verrucate, the margin raised, produced into angular marginal papilla towards ridge-apex, the median papilla absent or occasionally present, small, rounded, more or less isodiametric.
