Master's Theses and Doctoral Dissertations
The carnivorous pitcher plant genus, Sarracenia, has modified leaves adapted to lure, trap, and digest insect prey. Little is known about surface microstructural ornamentation and variation throughout the genus. Four zones of the leaf were examined in four species throughout the range of the genus using scanning electron microscopy (SEM). Nine unique microstructures were identified in the carnivorous leaf. For the first time, microstructures (N=880) were systematically measured and zonal averages were compared among zones (with MANOVA) and species (with PCA). Microstructures are significantly different among zones of the same leaf and vary among different species. These data suggest …
