Botany; Botany; Plants; Plants; Botanique; Botanique; Plantes; Botanique. 88 FORM OB FiaURB. 149 14T. Paltuate-vflined leaves. 147, Monispcrmiim Cnnadense. 148, Passifloro cerulea. 149, Broui- sonetift papyrllora. 150, Oak geranium. Leaves htc 2>almatehj cleft and palmatehj parted, according to the depth of the incisions as above described. But the most peculiar modi- fication is 273. The pedate, like a bird's foot, having the lowest pair of veinlets enlarged, recurved, and bearing each several of the segments (148). 274. The forms of the parallel- veined LEAVES are remarkable for their even, flowing outlines, diversified solely by the direction and curvature of the veins. When the veins are straight the most com- mon form is 275. The linear, long and narrow, with, parallel margins, like the leaves of the grasses—a form which may also occur in the pinnate-veined leaf, when the vcinlets are all equally shortened. The ensiform, or sword-shaped, is also linear, but has its edges vertical, that is, directed upward and downward. 276. If the veins curve, we may have the lanceolate, elliptical, or even orbicular forms; and if the lower curve downward, the cordate, sagittate, etc., all of which are shown in the cuts. The palmate or radiate form is finely illustrated in the palmetto and other palms, whose large, fan-shaped leaves are appropriately termed flabel' lifoTtn (f;u)-ph.npnd), 277. The leaves op the pine and the fib tribe (Conifera;) gen- erally are parallel-veined also, and remarkable for their contracted.
