Dr Lindley on botanical terms

986. The terms of botany have been described by Dr. Lindley as either collective or individual. The individual are again divided into the absolute and the relative; the absolute being those which relate to figure, division, surface, texture, size, duration, colour, variegation, and veining; and the relative, those which relate to ﾵstivation, direction, and insertion. The collective terms relate to arrangement and number. This mode of grouping the terms together is intended to facilitate the labour of acquiring them.
