Question

What is the leaf outline in these figures?

13 According to shape or outline leaves may, be linear when very narrow with nearly parallel margins and several times longer than wide; lanceblate when shaped more or less like a lance, three or morg times as long as wide, broadest below.and tapering upward or both upward and downward; oblanteolate, the reverse of lanceolate, widest above the,middle and tapering downward; oblong 26 when two or three times as long as wide, the sides nearly parallel and not conspicuously narrowed; 2lelliptic when shaped like n ellipse, broadest at the middle. tapering more or less equally to the base and tip, the width not distinctly more than one half of the length; oval when somewhat like elliptic but the width distinctly more than one half of the length; obtg when twice or less as long as wide, widest below the middle and more or less narowed upward; obovate, the reverse of ovate, widest above the middle and tapering downward; orbiedlar when circular in outline; spahilate when narrow, more or less rounded above, and tapering from near the apex to the, base; cuntđte or wedge-shaped yhen broad above, tapering by nearly straight lines to the base; falcate when more or less curve; flabeilate or fan-shaped when broad and rounded at the top, narowed helow like a fan; delidid when broad below tapering upwards and shaped like a triangle; reniforh when broader than long, shaped somewhat like a kidney. Combinations like ovate-lanceolate, oval-elliptic, etc., are used to describe intermediate forms while oblong to elliptic means both oblong and elliptic leaves are on the same plant or oval to obovate means both kinds are on the same plant. The prefix "sub" when prefixing a root word should be read as almost (e.g. suborbicular means almost orbicular).
