Hojas alternas, simples; peciolos de 2,5-3 cm de largo x 0,15-0,2 cm de ancho, glabros, pulvinuladas en la base; laminas glabras, cartaceas, oblanceoladas, 20-24 cm de largo x 5-6 cm de ancho, margen dentado, apices agudos, bases angosto cuneadas; vena primaria dominante en la superficie abaxial
, nervadura cladodroma.
The adaxial surface of the leaf had more trichomes than the abaxial
Cell shape is usually irregular in all species except Portulaca grandiflora Hook that is isodiametric on the adaxial surface and irregular on the abaxial
The vascular traces are difficult to discern, but at least one appears to show abaxial
indentation, a diagnostic feature of Artisophyton.
Adaxial matte surface to subnitid, glabrous or slightly hirtellous on midrib, abaxial
surface with the midrib, and sometimes lateral veins as well, most of which are slightly are puberulent or hirtellous and also with coarse, subapressed hairs, very densely tomentose, petiole 0.8-1.5 cm long (Fig.

Results indicated that the crosses4x5 with 44.8 stomata per mm 2 atthe abaxial
surfaceand 56.16 stomata per mm 2 atthe adaxial surface, 3x8 with 46.4 stomata per mm 2 atabaxial and 51.8 stomata per mm 2 ofthe adaxial surfaceand 4x5 with45.6 stomata per mm 2 at abaxial
and 53.44 stomata per mm 2 at the adaxial surfaceshowed maximum number of stomata per mm 2 at normal, stress and water holding sites, respectively.
The epidermis proportion on the adaxial and abaxial
surfaces was higher in the U.
The five branching types were lateral axillary branching, shoot apical division, false vivipary, abaxial
branching and leaf-opposed branching.
N: Virola sebifera--face abaxial
das folhas com tricomas estrelados.
The counts were made on both sides (adaxial and abaxial
) of 30 leaflets located in the upper third of the plant.
For the cross sections in the median third region, the total thickness of the leaf blade, adaxial and abaxial
cuticle, adaxial and abaxial
epidermis, mesophyll, palisade and spongy parenchyma was quantitatively evaluated (n = 30).
