Flowers hermaphrodite, regular. Calyx inferior; sepals 5 (very 
rarely 4) free or slightly (rarely more) united, more or less imbricate, 
equal or more or less unequal, often with (usually seale-like) glands 
near the base inside. Corolla salver- or funnel-shaped, rarely 
campanulate, urceolate or subglobose, glabrous or more or less hairy 
within, sometimes with scales or callous protuberances or ridges in 
the tube or mouth; lobes usually convolute, overlapping and frequently 
also twisted to the right or the left, very rarely valvate. Stamens 5 
(very rarely 4), inserted in the corolla-tube or mouth; filaments 
filiform or more often flattened and short or reduced to a callous 
swelling, often passing at the base into more or less decurrent 
ridges projecting into the tube (filamental ridges); anthers frequently 
conniving in a cone, either linear or oblong (rarely elliptic), shortly 
and obtusely 2-lobed at the base with the anther-cells parrallel 
polliniferous and dehiscing to the base, or sagittate with barren 
tails (very frequently formed by the continuation of the outher 
halves of the cells), leaving the front basal part of the connective 
(foot) free; foot of the connective smooth or with various shaped 
projections or regular groups of spreading hairs. Pollen nearly 
always spherical with 3 pores, loose or rarely more or Jess cohering. 
Disk if present annular or cupular, 5-lobed or consisting of 2—5 
scales, sometimes more or less adnate to the ovary. Ovary superior, 
or slightly inferior, of 2 (very rarely 3—5) united or distinct 
carpels, if synearpous, 1-celled with parietal or 2-celled with central 
placentas, if apocarpous with ventral placentas. Style 1, entire 
or divided at the base; stigma various, with or without a usually 
bifid apiculus and frequently with a ring or other appendages, 
viscous on the surface or exuding much glutinous matter and
