INTRODUCTION TO BOTANY.

LEAVES.

Triangular, &c, triangulare y &c,, according to the number of angles.Deltoid, deltoideum, rhomb-form of four angles, of which the colla-teral ones are less remote from the base than the others.Rhombic, rhombeam, the form of a rhombus.Trapeze-form, trapeziforme, the form of a trapezium.

The shape of Leaves is described thus:

Cordate, cord-atum* somewhat egged, hollowed at the base withoutposterior angles.

Kidney-shape, reni forme, roundish, hollowed at the base without pos-terior angles.

Lunate, lunatum, roundish, hollowed at the base, with posterior acuteangles.

Sagittate, sagiitatum, triangular, with posterior acute angles dividedby an interstice.

Hastate, hast alum., arrowed with posterior angles, divided by an in-terstice, prominent at the aides.

Runcinate, runcmatum % feather-cleft, so that the lobes, convex before,are the contrary behind, as Dandelion.

Fiddle-shaped, pajtduriforme, oblong, contracted below at the sides.

Cleft, Jissum, divided by linear hollows, w.th straight edges.

Lobed, lobatum, divided by the middle into distant parts.

Twice-fivecleft, iiqui/iquefidum, according to the number of the fis-sures.

Parted, partitum, divided almost to the base.

Palmate, palmatum, divided beyond the middle into equallish lobes.

Lyrate, lyratum, divided transversely into segments, of which the in-ferior less ones are more remote.

Pinnatifid, pinnatifidutn, divided transversely into horizontal oblongsegments.

Sinuous, sinuatum, with wide hollows on the sides.

Jagged, laciniatum, cut into various and indeterminate parts.

Ragged, squarrosum, divided into elevated shreds, parallel to theplane of the leaf.

The Margin, in shape is either

Very entire, integerrimum, the very edge linear, not in the least cut; or

Notched, trenatum, the margin cut into nicks, without any respect tothe extremities.

Sawed, serratum, all the nicks of the margin looking towards the ex-tremity.

Fringed, ciliatum, parallel bristles, longitudinally placed on themargin.

Toothed, dentatum, diverging remote points on the margin.

Thorny, spinosum, aw led, rigid prickly points on the margin.

Gristly, cartilagineum, with a boneyisb margin.

Scolloped, repandum, the margin winding yet flat.
