As to tiie nii/ifuj, or the arrangement of the fiamework in th(* bhido, loaves are divided into two classes, viz. : ist, the XrH^ulreinril or IMiralatcil ; !ind 2(1, th(^ Pnr<(//r/-ninri/ or \rrrrtf. 126. Netted-Veined or Reticulated leaves are those in which the veins branch off from the rib or ribs, and divide a^'ain and again, and some of the veins and veinJets run into one another, so formin<j reticulations or meshes of network t]ir9Ughout the leaf. 'I'liis is shown in ihii (4)uinco-leaf (Fig. <S2); also in the Linden or liasswood (Fig. St,^, and the IMaple (Fig. 84), whei'o the liner meshes appear in one or two of the leaves. I 27. Netted - veined loaves belong to ])lants which have a pair of seed-leaves to their em- bryo (48), and stems of the exogenous structun* (115). That is, these throe kinds of structure, iiv embryo, stem, and leaf, gonei'ally go togotlu'r. 128. Parallel-veined or Nerved loaves are those in which the ribs and veins run side by side without braiichin<j (or with minute cross-veinlets, if any) frouj the base to the point of the blade, as in lndiau-(Jorn, Lily of the Valley (Fig. 85), \c., or sometimes from the midrib to the mai-gins, as in the Jianana and ('alia (Fig. 86). Such [)arallol veins have been called Xfrveti, as just explained (124). Leaves of this sort belong to plants with one cotyledon to their embryo (47), and with endogenous stems {113).. 83. Linilcii.
