Reproductive type, pollination. Fertile flowers hermaphrodite. Unisexual flowers absent. Plants hermaphrodite.

Inflorescence and flower features. Flowers solitary (axillary); very irregular. The floral asymmetry involving the perianth and involving the androecium. Flowers cyclic; pentacyclic. Floral receptacle developing an androphore (inserted in a slit in the calyx). Free hypanthium absent. Perianth with distinct calyx and corolla; 7; 2 -whorled; anisomerous. Calyx 5; 1 -whorled; gamosepalous; unequal but not bilabiate (‘posticously dimidiate’). Corolla 2 (anticous); 1 -whorled; gamopetalous (the petals laterally connate into a slipper-like structure, hooded at the apex, externally sericeous); unequal but not bilabiate. Androecium 8, or 9. Androecial members free of the perianth; free of one another. Androecium including staminodes. Staminodes 4–5 (posticous). Stamens 4 (anticous); diplostemonous. Gynoecium 1 carpelled.
