Evolution was in the beginning applied to the species. When genetics established the independent inheritance of characters, evolution also began to be analysed in terms of characters or organs, each considered independent in its evolutionary trend. Subsequently, however, this rule of independence began to be violated in the attempts to determine evolutionary status by correlation. Furthermore, the circumscription of an organ for evolutionary correlation is equivocal. With regard to the vegetative and floral morphology of the angiosperms, the concepts of old formal morphology in terms of fundamental organs were more definite and evolution has not been able to offer anything better. Many of the concepts of formal morphology have
The principles laid down by Carlquist, in what he has proposed to be a function oriented approach to angiosperm morphology, appear to be based on undue assumptions with a mixing up of homology and evolution. The decline of evolution as the directive force behind plant morphology necessitates new approaches that could impart dynamism to this basic discipline of botanical study.

The present paper reviews the relationship between the procambium and the vascular cambium. It is suggested that the procambium is not a pre-requisite for the formation of vascular cambium, even in the stems, as is claimed by several morphologists.

The ontogeny of the embryoids arising from a variety of somatic and male gametophytic tissues has been compared to that of a zygote embryo; it has often been stressed that a free cell
