\textbf{Abstract}
\begin{abstract}
\normalsize{
The aim of this paper was to conduct a research study on the leaf morphological and anatomical stomata traits of ten native woody species that grow and develop in the Tamaulipan thornscrub, northeastern Mexico. Studied species, which are used for multipurpose uses, were Cordia boissieri, Helietta parvifolia, Condalia hookeri, Diospyros texana, Diospyros palmeri, Zanthoxylum fagara, Sideroxylon celastrinum, Karwinskia humboldtiana, Celtis pallida and Celtis laevigata. Studied leaf morphological characteristics were: leaf fresh weight (g), leaf area (cm$^2$), leaf length (cm), leaf width (cm), petiole length (cm), total leaf length (cm), leaf dry weight (g), leaf water content (g) and specific leaf area (cm$^2$/g). There were significant differences between species for all studied leaf morphological traits. The results show that the species C. boissieri achieved the highest values in most studied leaf characteristics, e.g., 0.41 and 101.4 for leaf water content and specific leaf area. In contrast, D. texana species registered the lowest values in seven variables which varied from 0.02 (leaf water content) to 3.18 (total leaf length). Correlation analysis between leaf traits showed a significant and positive relationship among variables. Correlation values ranged from 0.672 (leaf area vs petiole length) to 0.98 (leaf fresh weight to leaf dry weight). Besides, the results indicated that the species C. laevigata registered the highest stomatal density 69.95 stomata for mm$^{2}$ and the species H. parvifolia showed the lowest value (7.45 stomata for mm$^{2}$). Karwinskia humboldtiana showed the lowest stomata length (17.20 $\mu$m) while the species H. parvifolia obtained the highest value with 36.70 $\mu$m. With respect to stomata width, S. celastrinum showed the lower width 9.26 $\mu$m and the higher value corresponds to D. palmeri with 19.45 $\mu$m. Both morphological and anatomical leaf traits variation is related to phylogenetic variation among species and the adaptation to environmental conditions in terms of resource use and availability.}
