A BiTERNATE LEAF is formed when the leaflets of a ternate leaf give place tliemselves to ternate leaves, and triternate when the leaflets of a biternate leaf again give place to ternate leaves. 292. Palmately compoitnd. A distinction. The palmate vena- tion has also its peculiar forms of compound leaves, as ternate, quinate, septinate, etc., according to the number of leaflets which arise together from the summit of the petiole. Ternate leaves of this enation are to be carefully distinguished from those of the pinnate plan. The ^m/- mately ternate leaf consists of three leaflets, which are either all sessile or stalked alike ; the ^jJrareafeZy ternate has the terminal leaflet raised above the other two on the prolonged rachis (157, 158). 1T2 171.

Amplexicaul, when its base lobes adhere to and clasp the stem. 'Should these lobes extend quite around the stem and become blended together, on the other side a perfoliate leaf will be formed {per, through, folium, leaf), the stem seeming to pass through the leaves. 294. ConnIte denotes that the bases of two opposite leaves are united so as to form one piece of the two. OF TEXTURE AND SURFACE.
