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.
In Myrsinaceae some buzzpollinated taxa have a monosymmetric androecium (Ardisia speciosa, personal observation), and Coris has a bilabiate corolla (Stahl & Anderberg, 2004).
Its flowers are small, clustered into axillary inflorescences, hermaphrodite, pentamer, strongly zygomorphous and bilabiate.
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).
the relatively species-poor Oreobolus and Azorella, both with small, inconspicuous flowers, Calceolaria has conspicuous bilabiate flowers and diversified pollination biology (Molau, 1988; Cosacov et al.
Cassini (1816, 1819) proposed the tribe Mutisieae to include the genera with bilabiate corollas considered by Lagasca (1811) in his Chaenanthophorae and by de Candolle (1812) in his Labiatiflorae.
Florets dimorphic or isomorphic; marginal florets bisexual or female, corolla bilabiate, outer lip expanded or not; central florets or all florets bisexual, with corolla tubular-funnelform, deeply five-lobed; anther apical appendages truncate, reddish, tails papillose; style bifid, branches dorsally papillose.
Florets dimorphic with a gradual transition from marginal to central florets, marginal florets female, corolla true ray, filiform to bilabiate with a minute inner lip, outer lip expanded or not, with or without staminodes; central florets bisexual, bilabiate to tubular-bilabiate; anther apical appendages acute, tails smooth; style bilobed, branches dorsally papillose.
From Greek bolos, whole, all, entire, and cheilos, lip, because of the capitula with all the corollas bilabiate.
Corollas villose, central florets tubular-funnelform with equal to unequal segments, marginal florets bilabiate to sub-ligulate; anther apical appendages obtuse, tails long to short; style bifid to bilobed, branches smooth to dorsally papillose above or above and below the branch bifurcation point; pappus generally of plumose bristles, the bristles constituted by barnadesioid hairs, scaly, or rarely absent.
morphic or slightly zygomorphic to bilabiate (Ferdinandusa); rarely staminal flowers forming a pseudanthium (Theligonum).
