They are presented in a different rank than the other gemma leaf pairs and twisted 90[degrees] into the plane of the other two pairs and are arrayed so that their adaxial
surfaces are visible when viewed from above.
Unlike damage caused by Cephaleuros spp whose thallus produces a "red-rust" on the adaxial
(upper) surface of leave, the necrotic leaf regions caused by S.
The number of salt glands per unit leaf area was reported to be equivalent on the adaxial
and abaxial leaf epidermis in Aeluropus littoralis (Gouan) Parl.
Adults lay eggs on margins and veins of new leaves, and after 7 to 9 d, crawlers hatch and initiate gall induction on the adaxial
side of the leaves.
In later stages (V8-V10), the eggs are found in the middle and upper plant regions and on adaxial
Tree trunks, flower buds, flower cushions, basal chupons, cherelles and pods, fan branches, abaxial and adaxial
surfaces of leaves were closely observed for mirids on a fortnightly basis.
2006) verificaram necroses na face adaxial

Nymphs were more common on the adaxial
surface (55 %) than on the abaxial surface (45 %, n=580) of the leaves, with a mean of 3.
The flowers had two stamens inserted on the adaxial
surface of the petals; however, close investigation showed the
Leaves numerous, fleshy, very long and pendent; sheaths white to yellowish, broadly oblong to oblong, 5-6 x 3--5 cm, minute serrated especially toward the apical portion, white-lepidote on both surfaces; blades pendent in mature plants, light green at the adaxial
surface, densely white-lepidote on the abaxial surface, linear to narrowly triangular, long attenuated, 60-110 x 1-2 cm, minute serrated at the margin.
schneirlai on Amami-Oshima and Okinawa Islands of Japan is likely to use the enclosed chambers formed by floral bracts of Macaranga tanarius as breeding sites before and during flower anthesis, and feed on nectar on the adaxial
surface of flower bracts.
Semi-deciduous, thick blades, well-cutinized epidermises, numerous small leaves, sclerophyllic leaves, hypostomatry, sunken stomata, thickened epidermal cell walls, and abundant abaxial and adaxial
trichomes are characteristics of blackbrush plants, as well as typical woody xerophytic and sclerophyllous plants.
