The compound ones properly and dill:inetly fo calfed. 2. The decompound; and, 3· The fupradecompound; of each of which in it's place. In defcribing thefe kinds of leaves the whole leaf, which is the refult of the combination, is called folium, and the fmall leaves, which together compofe it, are called folio/a. A compound leaf, properly and dif~ tintlly fo called, is only formed of one fe ries of foliola, or of one compofition. Digitated expre.fies a compound leaf, formed of a number of fimple foliola, placed regularly on a common petiole: in a firiet fenfe, however, it is ufed only to expre[s fuch a leaf as is compofed of more than four foliola. 'Iernatum expreffes a compound leaf, <;onfifiing of only three leaves on a common petiole. Sej)ile expre.fies a leaf affixed immediately to the fialk, or root, without any petiole. Petiolate is the contrary of feffile ; it expre.fies a leaf afl1xed to a plant, by means of a peculiar pedicle, which pedicle, in cafe of a leaf, is called petiole, though, in cafe of fruit, a peduncle. Bz'natum' expreffes a kind of compound leaf, formed only of two foliola on one petiole. Ramulojitm expreffes a leaf of the compound kind, in which there are feveral foliola, full:ained on a branched petiole. Pimzated expreffes a leaf formed in manner of a wing, and compofed of two ranges; or feries, of foliola, annexed to the two fides of one common, oblong petiole. Of the pinnated leaves, however, there are feveral kinds: 1. The pinnated •with an odd om. This expre.fies the pinnated leaf, when, befide the two feries jufl: mentioned ~ there is an odd leaf at the extremity of the petiole. 2. The pinnated. abrupt leaf: This exprel1es a pinnated leaf in which there is neither an odd leaf nor a tendril at the end of the petiole. 3. The oppojitely pinnated ; which is when the folioles fiand oppo~ te to one another on the common petiole. 4· The alternately pinnate; when the fo holes. fiand no.t oppofite, but alternately. 5· The z'nterruptedly pinnate; in which the foholes are uregular and unequal in fize or fituation. 6. The cirrhated-pilmate, wherein the extremity of the petiole has one, or more, tendrils, infiead of an odd leaf. 7.
