. Beginners' botany. Botany. 74 BEGINNERS' BOTANY The method of compounding or branching follows the mode of veining. The veining, or venation, is of two gen- eral kinds: in some plants the main veins diverge, and there is a conspicuous net- work of smaller veins; such leaves are netted-veined. They are characteristic of the dicotyledons. In other plants the main veins are parallel, or nearly so, and there is no conspicuous network; these are parallel-veined leaves (Figs. 89, 102). These leaves are the rule in monocoty- ledonous plants. The venation of netted- veined leaves is pinnate or feath

These leaves are the rule in monocoty- ledonous plants. The venation of netted- veined leaves is pinnate or feather-like when the veins arise from the side of a continuous midrib (Fig. 91); palmate or digitate (hand-like) when the veins arise from the apex of the petiole (Figs. 88, 92). If leaves were divided between the main veins, the former would be pinnately and the latter digitately compound. It is customary to speak of a leaf as compound only when the parts or branches are completely separate Fig. 91. — Com- plete Leaves of Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bailey, L.
