Comparative Leaf Anatomy of South Texas Acacias.
The objective of this research was to compare the leaf structure of several common South Texas Acacia species. Plant samples were collected and prepared with conventional microtechnique and observed with light microscopy. Aspects of leaf anatomy were evaluated between species including features of epidermal, mesophyll, and vascular tissues. Preliminary results suggest that differences exist among the Acacia species, and also between the Acacia species and Prosopis glandulosa which was included as an outgroup. The most significant differences appear to be in the distribution and abundance of stomata on the upper and lower epidermal surfaces, mesophyll layer segregation and density, and the presence or absence of mesophyll tannins.
