Inflorescence a thyrse with sessile cymose part-inflorescences often reduced to 1 or 2 slightly stalked flowers, with internodes more or less elongating so that they are usually visible between the clusters of flowers, with subtending bracts usually shorter than the flowers; sepals unequally connate, 2-lipped, with the posterior lip 3-lobed, rarely 1 broad one, with the anterior lip deeply 2-lobed; corolla 2-lipped, with the posterior lip erect, more or less hooded, and scarcely 2-lobed, with the anterior lip with 2 narrow lateral lobes and a broader central one; stamens 2 fertile and 2 minute staminodes sometimes present, inserted in the throat of the corolla tube; anthers with 1 cell fertile at the end of a long curved connective which is continued into a broadened part beyond the filament terminating sometimes in an obvious sterile second cell; ovary deeply 4-lobed, with 1 basal ovule in each locule, with a gynobasic style and a terminal often unequally 2-fid stigma.

Fruit usually with 4 mericarps obovoid, vaguely triangular in section and scarcely keeled, with the attachment scar about circular, basal.
