Sandhya Panicker and V. K. Haridasan
Two species of plant Plumbago (family Plumbaginaceae) viz., Plumbago zeylanica and Plumbago auriculata have calyx covered with glandular trichomes. These structures entrap insects which are then gradually killed. This is most probably for protection, pollination, seed setting or protocarnivorous mode of nutrition. Besides various other morphological characters were studied to differentiate the species. The glandular trichomes were further studied under Stereo microscope and SEM.
