The dried, bilabiate
calyx, with its lips pressed together, falls from the parent plant with the mericarps enclosed.
Leaflets with both surfaces lepidote; calyx bilabiate
, lepidote, without nectaries; corolla yellow with red or brown nectar guides on the fauces .
Columnea chocoensis differs from any other known Columnea by having a long, dorsally recurved tubular corolla with a narrow bilabiate
limb, and exserted stamens and style.
3 cm Sepal Adaxially glandular Corolla orientation Erect respect to the calyx Corolla color Yellow Corolla limb symmetry Bilabiate

Petunia guarapuavensis has a large, evidently vertically bilabiate
stigma located at a level similar to the anthers of long stamens (Fig.
Its flowers are small, clustered into axillary inflorescences, hermaphrodite, pentamer, strongly zygomorphous and bilabiate
The anthesis lasted approximately 5 hours on sunny days or 9 hours on rainy days, the right wing covered the left wing, the corolla acquired a bilabiate
aspect, offering the left wing as landing platform; they produced a low quantity of nectar (0.
It has foot-long flower wands that are studded with pinkish white bilabiate
blossoms and violet calyces.
Mints are grouped together because they have several distinguishing characteristics such as square stems, wood leaves in pairs opposite on the stem and bilabiate
(two lipped) corollas (the flower petals).
2) diurnal nectar production in concentrations between 12-25 % (Amaya-Marquez 1996); 3) tubular corolla that is basally spurred, often sigmoid, the tube slightly inflated, straight or dorsally curved, less often funnelform, and the limb bilabiate
or subactinomorphic, 1 to 7 cm long (values that match most of the range in hummingbirds' bill length); 4) corolla tube color orange, red, or yellow, sometimes with contrasting nectar guides on the limb; 5) calyx and bracts may be of the same color as the corolla, in which case the reproductive structure, as a whole, contrasts with the foliage; and 6) in other cases the calyx and the bracts are colored differently than the corolla, and the final result in both cases is an increase in the visual impact.
Classical cases of conspicuous monosymmetry are bilabiate
flowers, which appear in two extreme forms: keel flowers and lip flowers, with the pollination organs more or less hidden in a container: either the keel (on the lower side) or the upper lip (on the upper side) (Endress, 1994; Westerkamp, 1997; Classen-Bockhoff et al.
