PLATE 14 
Diversity in crazy-top plants. Upper portions of two affected plants, showing 
differences in the production of leaves, in the retention of floral buds, in the 
shortening of the joints of the fruiting branches, and in the shape and size of the 
involucral bracts. In some cases the flower buds are retained and the leaves 
suppressed, as in the left-hand plant, or the growth may be more compact, 
forming a rather close spike of floral buds with no leaves. (Natural size.)
