Morphology Reproductive morphology Flowers Calyx
Calyx tubular to infundibuliform, actinomorphic to zygomorphic, rarely 2-lipped, 5-lobed, rarely sinuses appendaged and appearing 10 lobed, lobes sometimes obsolete, lobes usually equal, deltoid to subulate or filiform, rarely uncinate, erect to spreading
Morphology Reproductive morphology Flowers Corolla
Corolla strongly 2-lipped, 5-lobed (2/3), white or cream to lilac, pink or bluish purple, rarely red, posterior lip erect, anterior lip apiculate or rounded, rarely explosive pollination mechanism non-functional with lip cochleariform, corolla-tube ± infu
