Morphology Reproductive morphology Flowers Corolla

Petals bright yellow, 1/2–2/3 the length of the sepals, oblong, narrowly obovate or obovate, often 2-dentate at the apex, either with a basal nectariferous claw which is circumvillous within ledged above and glabrous on the back, or with the gland entirely lacking.

Morphology Reproductive morphology Flowers Androgynophore

Androgynophore 1 mm. long, glabrous but villous at the apex producing a cushion that bears the stamens, or with the basal glabrous portion lacking in specimens with no nectaries.
