Sarracenia leucophylla , the white-top pitcher, is another southern pitcher and perhaps the showiest, with the white upper areas of the tubes contrasting strikingly with darker venation
petiole 7-23 mm long, smaller than the rachis; 1 extrafloral nectary, green-vinaceous, sessile, pyramidal, 1-3 mm long, located on the rachis, between the proximal pair of leaflets; rachis 13-15 mm long; leaflets discolorous, 2 pairs, semisucculent, adaxial surface pilose, abaxial surface tomentose, obovate to elliptic, 21-88 X 9-41 mm, apex rounded, base assimetric, venation
penninervous, midrib excentric.
The genus is unique within Phaneropterinae in that the tegminal venation
with all main branches in the strongly widened medial field are curved dorso-anteriorally i.
5-3 cm, base nearly round, truncate or slightly cuneate, margins with short and triangular teeth, each ending in a callose papilla, apex acuminate to cuspidate, green and often suffused with purple and slightly puberulous on the abaxial surface, venation
brochidodromous, secondary veins 6-8 pairs, ascending in ca.
Here, a couple of trees had smaller, less leathery leaves in which the longitudinal venation
was not so prominent; the branchlets were not glaucous and some had a heavy bud crop with umbels of up to 13 flower buds.
Individual leaf of each species was examined and the morphological characters texture, leaf shape type, midrib colour, leaf colour, venation
type, leaf margin, leaf base, leaf apex were noted and entered in a table.

Genus Proan Haliday comprised of aphid parasitoids having wing venation
with recurrent vein developed; interradial vein effaced, notaulices distinct throughout, lateral lobes of mesonotum setose (Raychaudhuri, 1990; Kavallieratos et al.
These adults were with three dim longitudinal lines on thorax, their abdomens were dull white and in length,with folded legs, transparent wing with less venation

patterns, vascular bundles, and leaf blade edges.
Shape of inflorescence, thickness of peduncle, venation
of leaflet, and apex of floral bract (characters 10, 12, 9, and 13) were most important for determining the component score of the first axis; shape of rachis gland and length of leaflet (characters 3 and 7) were most important for determining the second axis, whereas the most important character for determination of the third axis was symmetry of stipular spine (character 1).
The second step involves the diffusion of melanin precursors from the hemolymph of wing venation
system (True et al.
