Original diagnosis/description

Bracts and prophylls of inflorescence broadly triangular, tapering into an acuminated apex; epidermis cells with distinct undulate anticlinal walls. Pistillate inflorescence subunits with one or two flowers that develop mature fruits. Pistillate flowers borne on a short peduncle. Perianth consists of four to five small acicular perianth parts. Fruits obovoid to almost spherical. Four to five vascular bundles are present in the outer fruit wall marked by narrow ribs extending from the base of the fruit to the base of the perianth. Apical slit lined by densely spaced, simple trichomes. Fruits indehiscent and apparently dry. Staminate inflorescence subunit with four or five flowers. Typically, not all stamens in each flower develop fully. The surfaces of the inflorescence and floral organs, except for the anthers, bear long, unicellular trichomes with acute apices and simple, slightly swollen bases.
