The leaf has a different texture on each side; the abaxial ( top ) side of the leaf is hairy while the adaxial ( bottom ) side is smooth.
32.
In a typical leaf, the stomata are more numerous over the abaxial ( lower ) epidermis than the adaxial ( upper ) epidermis and are more numerous in plants from cooler climates.
33.
Stomata on all faces of the leaves, in 4-6 (-7 ) lines on the convex abaxial face and 2-3 ( 4 ) lines on each adaxial face.
34.
The sori are borne on the abaxial surface "-not a good idea to link abaxial to a huge page where the word is lost, maybe link to wiktionary definition instead.

36.
It is characterised by a short rhizome which gives rise to several green fronds that have a pinnated lamina with trichomes on the abaxial ( lower ) surface, but not the adaxial ( upper ) one.
37.
Like " Neuwiedia " with 3 fertile stamens, the other genus of the same subfamily, " Apostasia " is noted for having 2 fertile, abaxial stamens instead of one like other orchids.
38.
There are four central spines ( 4-5 per areole ), where the lower central spine is white, abaxial central spines are tinged, is gray-purplish, angled, and strongly hooked and slightly contorted.
39.
"' Leaf Anatomy "': The leaves of all species are built on a dorsiventral arrangement of cells, with the epidermis and palisade layer on the adaxial surface and the spongy tissue on the abaxial surface.
40.
When an angulation of the whorls occurs, the space between it and the suture above it ( i . e . the abaxial edge of the sutural ramp ) constitutes the area known as the " shoulder " of the shell.
