PAKALLEL-VEINED LEAVES. 89 18. Digitate (finger-shaped),, having narrower and deeper segments than the pahnate, as hi the hemp, i 19. Pedate (foot-shaped). The same as pahnate, except that the tvi^o lateral lobes are themselves subdivided, as in the peony and passion-flo\ver.\ 20. Laciniate (gashed),/the veins and veinlets separate, as il the blade were cut and gashed with scissors. Ex. Ranunculus.; 21. Peltate (shield-hke), the veins radiating in all dhections, and all connected by intei-venuig tissue. Tliis form is gener aUy also orbicular, and appears to residt from the union of tlie base-lobes. Ex. PodophyUum peltatimi, Tropeolum, Brasenia.) 22. Reniform, broad-ovate, broad-cordate, &c.,/may also result from the radiate veining.' 234. The form of parallel-veined leaves is less diversified than that of the preceding classes, being 23. ienear, when the vehis (and fibres) are straight, as in the grasses. Tliis form may also occur ua the feather-veined leaf ' by an equal development of all the veinlets as in Linaria vul garis, &c. -. FIG. 31. —23, 24, 25, figures of leaves with paraUel veins; 2 — 10, margins of leaves. 24. Oval, lanceolate, oblong, or some kindred form, when the veins are cm-ved, as in Cajrex, Cypripedium, Orchis, &c., or it may^be ' 25. Cordate, when some of the lower veins are curved back- wards and then upwards, as in Pontaderia, and eve^ sagittate, when they are directed downwards at the base, as in the Sagit* taria. ?.
