Cleome viscosa L., a multipurpose species, is reproductively versatile exhibiting variation in the sex of its flowers. Being predominantly andromonoecious, few plants occasionally exhibit functional monoecy. Andromonoecy is distinguished by the production of hermaphrodite and staminate flowers, while formation of pistillate, male and other intermediate flower types leads to functional monoecy. Size variation in these sexes is equally prevalent. Size dimorphy in all the flower types leads to significant differences in almost all the morphological features. Overall 12 different flower types thus distinguished were analysed for different morphological traits. The data generated were subjected to correlation analyses to determine the extent of relationship between them, and thereupon reflect on the mechanism of their selection in flowers of different sexes and sizes. Despite male fitness traits being at greater advantage in all flower types, female fitness is equally selected in hermaphrodites and exclusively in pistillate flowers. Others with staminodes show mixed fitness. A critical analysis of the morphological data and their correlations suggests that different pairs of traits in each flower type are evolved in ways unique to them and to maximize their functional potential. Natural selection is thus operating through differential correlation patterning and is probably driving the evolution of these flower types.Keywords

Hippophae rhamnoides L., commonly called sea buckthorn, is a core dicot of the family Elaeagnaceae placed in the order Rosales. The plant is a treasure trove of bioactive substances with a potential to sustain more than one kind of industry. Countries with its natural populations are eyeing it as a new millennium food, as well as health and beauty resource. Valued for all its parts, the species is prized particularly for its fruit pulp and seed oil, which among others are a rich source of vitamins and omega-3 fatty acids. In Jammu and Kashmir (J&K), India, the species grows luxuriantly in Ladakh along riversides of the Indus, Suru, Shyok and Zanskar. H. rhamnoides L. is strictly dioecious in majority of the populations surveyed.Full Text

Angiospermic plants are known to follow a wide range of breeding systems from obligate inbreeding to complete outbreeding. Legumes among these exhibit inbreeding as the predominant mode, which they achieve by self pollination. The sexual apparatus of Lathyrus aphaca L. seems to favour out-crossing both structurally and functionally. However, an interesting mechanism known as ‘Flexistyly’ facilitates and ensures fruit production through autogamy. A part of style bears trichomes known as ‘pollen brush’ which undergoes curvature, exhibits movements and deflects towards the dehisced anther to catch hold of maximum pollen for its reproductive assurance. The present communication elaborates this fascinating mechanism.Keywords
