Ovate, obovate, oval; these are terms derived Irom tne Latin ovum, an egg ; suppose the figure at 28, a, to represent an egg, you observe that one end is broader than the other, now if to this broad end you add a petiole prolonging it into a mid-rib with some lateral divisions, you have, as at b, the re- presentation of an ovate leaf. If the petiole, were placed at the narrowest end, it would be an obvate leaf. An oval leaf (c) is when both the ends are of equal breadth
. Botany for beginners: an introduction to Mrs. Lincoln's Lectures on botany. Plants. 50 BOTANY FOR BEGINNERS. | Ch. IX. 194. Ovate, obovate, oval; these are terms derived Irom tne Latin ovum, an egg ; suppose the figure at 28, a, to represent an egg, you observe that one end is broader than the other, now if to this broad end you add a petiole prolonging it into a mid-rib with some lateral divisions, you have, as at b, the re- presentation of an ovate leaf. If the petiole, were placed at the narrowest end, it would be an obvate leaf. An oval leaf (c) is when both the ends are of equal breadth. When the length is much greater than the breadth, the leaf is said to be elipti- ral, as at d. Fisr. 195. Lanceolate, this kind of leaf may be seen in the peach tree; it is represented in Fig. 29, a; this has a serrulated or slightly notched margin; at b, may be seen the cleft stipules, or appendages of the leaf. 196. Linear, as the grasses and Indian corn, Fig. 29, c, re- presents a leaf of this kind; it is sheathing, or encloses the stem by its base, as may be seen at d. 197. Deltoid, from the Greek letter delta A; this kind of leaf is represented at e, Fig. 29; the Lombardy poplar affords an example of the same. 194. Describe the terms ovate, obovate, and oval. 195. Describe a lanceolate leaf. 195. What is a linear leaf? 197. What is a deltoid leaf?.
