It is characterized by digitate leaves with lepidote indumentum, flowers with bilabiate calyx, lepidote and corolla yellow with red or brown nectar guides on the fauces.
4 cm; limb bilabiate, oblique, upper limb formed by the two dorsal lobes (which form an ample galea) and the two lateral triangular lobes, the ventral lobe 1.
3 cm wide at limb, the limb bilabiate and oblique, the upper lip formed by the two dorsal and the two lateral lobes, 1.
Lamiales are a huge clade in terms of species, genera and families with monosymmetric, often elaborate bilabiate flowers (Kampny, 1995).
Other cases with stronger monosymmetry are: Sprekelia (Amaryllidaceae), in which, in addition to mere curvature, the perianth is conspicuously monosymmetric (Vochting, 1886); Haworthia and Chortolirion (Asphodelaceae) with bilabiate perianth (Smith & Van Wyk, 1998); Daubenya with three enlarged petals in basal flowers of the inflorescence, and Lachenalia (Hyacinthaceae) with a bilabiate perianth (Speta, 1998); Melasphaerula, Sparaxis, Chasmanthe and perhaps other Iridaceae-Ixioideae with bilabiate or otherwise monosymmetric perianth (Vogel, 1954; Goldblatt et al.
9 cm Corolla limb Bilabiate Subactinomorphic Stamen filaments 2 cm 3.
He emphasized types of capitula in his classification and included in the Mutisieae genera with other types of corolla than the bilabiate, such as ligulate and tubular corollas.
Cabrera defined the Mutisieae as having bilabiate corollas, caudate anthers, and characteristic style shape.
