Morphology Reproductive morphology Flowers Corolla
Corolla medium to large, campanulate, lobed almost to the base
Morphology Reproductive morphology Flowers Corona
Corolline corona absent. Gynostegial corona of 5 lobes, often fleshy, sometimes dorsally flattened, united very briefly at the base and attached to the gynostegium near the base of the anthers; gynostegium usually with a conspicuous stalk below the attachment of corona lobes
Morphology Reproductive morphology Flowers Gynoecium Style
Stylar head truncate, 5-angled, generally ± level with the top of the anthers and largely obscured by the anther appendages; corpusculum ovoid, brown or black; translator arms flattened, broadened and geniculate near the attachment of the pollinia, held ± at right angles to the axis of the corpusculum.
