. Botany for academies and colleges: consisting of plant development and structure from seaweed to clematis. Botany; 1889. 94 ACADEMIC BOTANY. simple Flo. 126.—Ohaste-tres {VUexAgnm- CastuB), with sepa. fr. Odd -pinnate [impari-pm- nate), with a leaflet at the apex; Locust, Boswellia (Fig. 125) ; Interrupted- pinnate, interrupted by small intervening leaflets; Agrimony (Fig. 129); Bi- pinnate when the leaves are still further corn- pounded by branching once ; Mimosa (Fig. 130); here the branches are called pinnce (L. pinna, feather); Tri-pinnate, when thrice - branched ; the last branches called pinnules {h. pinnulce); Venus' Maiden-hair Fern. The Mimosas furnish ele- gant examples of bi-pin- nate forms. The Silk- flower-tree so common in The part of the common petiole to which the leaflets of a pinnate leaf are at- tached is called the rachis (Gr. spine). Palmate leaves have no rachis; each leaflet is jointed to the common petiole at a common point. Sometimes in the pinnate leaf each leaflet has a petiole; this is called a petiolule; if it has a stipule, this is called a stipel. 198. Pinnate Leaves. The most reduced pinnate leaf is that ofthe Lemon (Fig. 127). Though one-leaved, it is jointed to the pe- tiole, a character never found in the simple leaf. 199. Pinnate leaves are: Unifoliolate ; Lemon (Fig. 127); Bifoliolate, Binate; Bignonia; Trifoliolate, Ternate; Dew- berry (Fig. 131); Multifoliolate; Wis- taria, Locust; Even-pinnate (pari-pin^ nate when the leaflets are in pairs with no end-leaflet), Guaiaoum (Fig. 128);.
