Abstract
STUDIES on the morphological features of four species of genus Sida L.; viz. Sida acuta Burm. f., Sida cordata Burm. f., Sida cordifolia L. and Sida rhombifolia L. belongs to family Malvaceae have been conducted in the present study. These species grow widely in the Agra city of western Uttar Pradesh; India. The present work focused on the determination of variations in the morphological attributes of the leaf, calyx, petal, staminal tube, stigma and trichomes, using compound microscopy to examine some minute morphological features. The overall study revealed that morphological characteristics in the four species of genus Sida exhibit considerable variation. S. rhombifolia leaf has a rhomboid-shaped lamina, while the rest of the studied species have cordate-ovate to suborbicular-cordate and linear shapes. S. acuta has large sized corolla (1.5cm in diameter), and calyx (10mm in diameter) followed by S. cordifolia (8mm), S. cordata and S. rhombifolia (7mm). Trichomes showed a wide variation from glandular to non-glandular, unicellular to multicellular, spiral, straight, stellate, branched and unbranched. Therefore, the study could be exploited as a baseline tool to characterize and identify the individual species of the genus Sida.
