This subgenus was described by Reeder and Roth, (1988) based on "a prominent bulge at the anterior end of the upper, double-tubed chamber of the penis", and a flattened, papillose
Siderastrea siderea forms larger colonies and larger corallites (3-5 mm) than the other species, has numerous septa (44-50), deep and papillose
columellae, and thin synapticulae; and the septa alternate between corallites (Yonge, 1935; Laborel, 1970; Budd and Guzman, 1994; Beck, 2005; Menezes et al.
5 mm long, twice as much as petals, in two series, opposite and alternate to petals, filaments inserted on edge of annular, papillose
disk; pistillode <1 mm long, reduced and rarely functional.
Leaves lanceolate, papillose

Peristome double, exostome cross-striolate below, papillose

, membrane basal high, cilia none.
The cuticle of the trichomes is papillose
Acanthosis nigricans (AN) is characterized by hyperpigmented and papillose
thickening of the epidermis, which is mainly present on the skin folds, such as the axillae, posterior neck, umbilicus, and occasionally mucosal surfaces [1, 2].
with inconspicuous indumentum, devoid of epicortical roots.
The carnivorous Mantophasmatodea also have a large proventriculus "armed with weak, papillose
sclerites that terminate in three successive whorls of weakly sclerotized lobes" and an undifferentiated midgut (Klass et al.
The stigmatic surface is composed of unicellular simple short trichomes in Hymenaea courbaril (Figs, 1b and 4b); papillose
cells in Bauhinia curvula (Figs, 1a and 4a), Caesalpinia echinata (Fig.
The stigma becomes receptive just prior (1 to 2 h) to anther dehiscence and is fleshy, papillose
, and light violet (Chauhan et al.
The mouth is large, the lips fleshy on the outside and horny on the inner surfaces, and the lower lip is papillose
