The rooistocA'(. 1 is a thickened iii.clerj^nmnci stem several times longer tliaii broad. The iudif ( 5 ) i.s a rootstock ihi'-kencd at one end, as in the edible .so-called " roots " ot the Irish ])otalo. The rcrw (6) is a compact and rounded rootstock. The iii//> (7) is a corm, the greater pavt of which is made up of fleshy scales. Stems have two principal wavs of fiimbhn;, by twining bodily around tlie supporting object; or by the aid of tenctnli, modif ed brandies or leaves wliicli serve as holdfasts, as in the X'irginia Creeper.

They are doubtless designed to protect the plant against animals that would strip it of its bark or leaves, if undefended. l.uives are appendages of the stem, whicli serve as the digestive organs of the plant. They assimilate the crude sop of the plant into material for building up its tissues. Leaves are arranged on tlie stem in two principal ways. They are aUiynali when tliere is but one at each ioint; and w/wrlcti, wlien there are more than one. 'hen the whorl consists of but two leaves, they are said to be opposili. Tiie lanre usually ilat part of the leaf is called the blade. The stalk wliicli bears the blade is the f^etiolc. The two small blade-like bodies at tlie base of the petiole are the .f/ii/«/«'.f (8). When the petiole is wanting, the blade is sessile. The stipu'es are often absent or inconspicuous. There are two principal modes of vciniug in leaves. When the veins braiidi again and again, and the branches run together so as to form a network or mesii, the leaf is iiel-vehted (q. When the veins run side by side without seeming to branch or r
