There is a single apical pore, lacking an operculum, but showing a recessed bilabiate germination mechanism (Fig.
From this, we infer the germination mechanism to be recessed bilabiate.
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.
In Myrsinaceae some buzzpollinated taxa have a monosymmetric androecium (Ardisia speciosa, personal observation), and Coris has a
bilabiate corolla (Stahl & Anderberg, 2004).
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.
Florets dimorphic; marginal florets female, with staminodes, corolla
bilabiate, outer lip expanded; central florets bisexual, corolla
bilabiate; anther apical appendages acute, tails papillose; style bilobed, branches dorsally papillose.
Florets dimorphic; marginal florets female, with well developed staminodes, corolla
bilabiate, with an expanded outer lip; central florets bisexual, corolla
bilabiate; anther apical appendages acute, tails papillose; style bilobed, branches dorsally papillose.
Florets dimorphic or isomorphic, bisexual; marginal florets with corolla
bilabiate, outer lip expanded or not; central florets with corolla
bilabiate; anther apical appendages acute, tails smooth; style bifid, branches apically truncate, crowned by collector hairs.
Florets bisexual, radiate capitula with marginal corollas
bilabiate, outer lip expanded; central corollas actinomorphic, tubular-campanulate, deeply five-lobed, tube narrow, abruptly dilated into a limb, lobes erect; discoid capitula with florets actinomorphic, corollas tubular-campanulate; anther apical appendages acuminate to apiculate, tails papillose, long, subrounded; style bifid, branches separate, dorsally pubescent and also hairs in subapical ring, hairs acute.
