(2010) from Balkan peninsula and they found glandular (peltate
, unicellular capitate, multicellular capitate), and non-glandular (unicellular unbranched, multicellular unbranched) trichomes on the leaves of this species.
pseudomarrubioides have been reported to have short-stalked peltate
trichomes  and this likewise corroborates the current leaf micromorphology study where the two species have been reported to have short-stalked trichomes.
Both capitate trichomes (Figure 2(a)) and peltate
trichomes (Figure 2(b)) were orange after dyed with Dragendorff reagent.
 reported that the environmental conditions such as light could play an important role in increasing or reducing the synthesis and in the accumulation of the essential oil in peltate
trichome glands of Lamiaceae species such as spearmint.
Taro (Colocasia esculenta, L) is a vegetatively propagated, perennial tropical crop with a large peltate
("shield-shaped") or heart-shaped leaves, in contrast to xanthosoma whose leaves are hastate ("spear shaped") or arrow shaped.
A quadrangular four-lobed, persistent floral tube includes a single stout style with peltate
Floral bracts peltate
, 0.7-1.1 mm long, apex circular and glabrous, deciduous.
This species is distinguished by the corticate and regular scyphose podetia cover with peltate
and flat squamules in upper part.
The squamules can be convex, concave or convoluted, erect and elongated or flat and [+ or -] distinctly peltate
, brown, olivaceous or blackish, matt, glossy or often covered by a bluish white pruina; the apothecia remain completely immersed or are secondarily raised above the thallus surface and then surrounded by a thalline margin.
The petiole can also add to the overall leaf variability by being short or long, attached to the middle of the blade (peltate
) or to the edge as is normal or even absent.
Scales are peltate
, with a 1-cellular base, an irregular to stellate body with divergent arms that end in blunt or acute cells.
