A large order which gets its name from having its flowers compounded of numerous small ones called florets which are enclosed in bracts, resembling a calyx, called an involucre. The calyx springs from the top of the ovary and becomes a pappus, i.e. a feathery head around the fruit such as the pappus of dandelion. The prevailing color of the flowers is white and yellow.
In the Dandelion group the florets are strap-shaped pistil.
In the thistle group the florets form a convex head and are all tubular. Flowers mostly purple.
In the Tansy group all the florets are tubular and perfect and form a flat head.
In the Daisy group the flowers are of two kinds, those of the centre or disk are tubular and perfect, those of the margin or ray, strap-shaped and have pistils only. The disk is generally yellow, except in cilloea in which all the flowers are white. The ray is either of the same color or white as in aster.
