A BiTERNATE LEAF is loFincd wlieii the leaflets of a teniate leaf give place themselves to ternate leaves, and triternate when the leaflets of a biternatc leaf again give place to ternate leaves. 292. Palmately compound. 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 venation are to be carefully distinguished from those of the pinnate plan. The pal. matehj ternate leaf consists of three leaflets, which are either all sessile or stalked alike; the pinnately ternate has the terminal leaflet raised above the other two on the prolonged rachis (157, 168).

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. Connate denotes that the bases of two opposite leaves are united so as to form one piece of the two. OF TEXTURE AND SURFACE.
