The arrangement is generally progressive, as in nature a plant develops outwards and onwards from the root, and the orthodox scroll ornament may be considered as a stem of undulate form (constituting the growth line) with branches, elaborated with leaves and flowers which are arranged successively.
Branching
In traditional ornament the most general form of branching is tangential, the scrolls and leaves emerging radially from the main stem, with slight divergence; but in nature many varieties of branching may be observed and applied with advantage in design.
No. 243. Types of Branching.
A. Tangential. B. Acute-angular. C. Right-angular.
Generally natural branching may be classified into Tangential, typical of grass growth and water-plants; Acute and Right-angular. The latter is sometimes usefully employed in ornament, as it conveys a sense of strength and vigour, though as a concession to the rhythmic flow of line it should follow for a short distance the curve of the main stem.
