In a low deciduous forest in Yucatan, Mexico, we describe the architecture and analyzer the morphometry attributes of Caesalpinia gaumeri and Gymnopodium floribundum in three size classes and two soil types. Caesalpinia gaumeri is used in rural construction and G. floribundum in beekeeping. We identified and classified 24 trees of both species in three size classes: seedlings, saplings and poles, in soil luvisol and leptosol. The architecture of C. gaumeri corresponded to the model Troll and G. floribundum is Champagnat. Both species showed reiterations related of natural causes. We found statistics differences for morphometry attributes between size classes and soil types for both species. The tree poles of C. gaumeri were higher (Tukey, P ≤ 0.05) in diameter at breast height, total height of crown and total height a first branch, lengths of branch of first order and internodes between size classes. The trees of this species growth in soil luvisol were higher (Tukey, P ≤ 0.05) in diameter at breast height and insertion angle of branches of third order compared with trees growth in leptosol. The trees seedlings of G. floribundum were higher (Tukey, P ≤ 0.05) in insertion angle of branches of first order compared with saplings and poles. The trees of this species growth in soil luvisol were higher (Tukey, P ≤ 0.05) in insertion angle of branches of second and third order compared with trees growth in leptosol.
