Abstract
Similar developmental mechanisms for leaf shape throughout the Malvaceae are postulated on the basis of like development in Hibiscus rosa-sinensis, "Apricot," and Gossypium, and similarities between leaves of various spp. of Malvaceae and those produced by various genes within Gossypium. Inter-generic and interspecific barriers probably limit greatly the expression of which a single gene is capable when placed on different backgrounds. For example, the potentiality of forming a secondarily entire leaf is expressed in Hibiscus, but never in Gossypium. The occurrence of dissected cotyledons in wild spp. of Gossypium may represent an advance in timing of the action of genes for laciniated leaves.
