	abstract = {We propose a hypothesis for the derivation of flowers and reproductive structures in the Alismatidae (Helobiae) which is based on evolution of features of {\textquoteright}flower{\textquoteright} and {\textquoteright}inflorescence{\textquoteright} in different ways from an ancestral pre-floral condition with a multiaxial reproductive structure. We base this proposition on the existence of many cases of structures with attributes of both {\textquoteright}flower{\textquoteright} and {\textquoteright}inflorescence{\textquoteright}. In one suite of cases the lateral axes appear to have become flower-like while the main axis has become an inflorescence axis; in another the axes have become inflorescence-like proximally and flower-like distally. Like other evolutionary plans, it can also be read in the reverse direction, and would then imply that features of {\textquoteright}flower{\textquoteright} and {\textquoteright}inflorescence{\textquoteright} had become re-partitioned in different ways in the group. We interpret as reduced the simpler forms of flower among the group.},

	pages = {91-108},
	abstract = {Evidence exists for genetic variation that can be associated with the evolution of adaptations to flooding: variation related to flooding at the level of molecular mechanism; comparisons of the patterns of variation in flooding-tolerant and non-tolerant species; within-species variation associated with genetically-differentiated populations that enable certain higher plants to tolerate or avoid the effects of flooding are understood. Yet little is known of the genetic basis for these features and less of its variation. An analysis was done of Salicornia, which exists as locally differentiated populations in different tidal flooding regimes, from the lowest to the highest parts of salt marshes. Genetic differentiation can be demonstrated by significant selection coefficients against alien types in reciprocal transplant experiments. The genetic variation within and between these populations were investigated using restriction fragment length polymorphism studies of the ribosomal DNA (rDNA). Two rDNA repeat unit types were found, only one of which occurs in any individual plant. Only the 12-kilobase (kb) fragment was found in populations that experience the most flooding, whereas plants on the highest parts of the marsh had only the 10.5-kb fragment. Typical lower and upper marsh populations were mixed in their fragment compositions, but lower marsh areas supported a higher frequency of the 12-kb fragment than upper marsh and depressions supported a higher frequency of the 12-kb fragment than raised interfluve areas. The use of such DNA variation, which is itself unselected , as a marker for selected genetic variation shows considerable promise for the future.},
