Larvae that feed on the abaxial leaf surface can reduce predation risks because the probability of being detected by a predator is lower on the abaxial than the adaxial
surface (Krebs & Davies 1993) as reported for sucking insects and ants on C.
petiole 33-39 mm long, slightly larger with rachis; 1 extrafloral nectary, black, sessile, pyramidal, 1-2 mm long, located on the petiole; rachis 23-110 mm long; interfoliolar segments 13 34 mm long; leaflets discolorous, 4 pairs, membranaceous, adaxial
surface glabrous to sparsely pubescent, abaxial surface pilose, lanceolate to elliptic, 17-65 X 9-37 mm, apex acute to cuneate, base assimetric to cuneate, venation penninervous.
En la superficie adaxial
es comun observar un solo tipo de tricoma, pero en la superficie abaxial pueden presentarse dos o hasta cinco tipos (Cuadro 2).
1 and 2 = Adaxial
side; 3 and 4 = Abaxial side; 1 and 3 = high density population; 2 and 4 = low density population.
Rogers and Ogg (2001) reported that stomata number were two to three-fold higher on abaxial than on adaxial
epidermis of the Solanum species (S.
The stomatal index on adaxial
surface did not vary with the growth stage of the plant or with the biotype (Table 2).
The anatomical characters studied were nature of adaxial
and abaxial epidermis, occurrence of sclerenchyma strands and girders, number and position of vascular bundles, arrangement of chlorenchyma cells, nature of keel, and shape and distribution of bulliform cells.
To prepare the abaxial surface, the leaf were placed keeping its adaxial
surface upward and then it were flooded with 88% cold lactic acid.
Se distingue de las otras especies por tener ramitas jovenes teretes, cara adaxial
de la lamina con tricomas simples, estrellados, fasciculados y multirradiados, margen entero, mucron del apice glabro y peciolo eglandular (Fig.
Corola rotacea, verde claro, tubo breve, lobulos oblongos pubescentes en la cara abaxial y base de la adaxial
surface glabrous and abaxial surface glabrous to glabrescent, sometimes with stellate trichomes, or simple, dispersed mainly in the primary vein (midrib) and less times in secondary veins.
lineata el labelo es reflejo, oblanceolado, discolor, anaranjado con lineas coloradas a rojizas sobre base amarillenta en la cara adaxial
y en C.
