| Sumario: | Foliar characters in ten Neotropical and Argentine species of Canna (Cannaceae-Zingiberales). A study of epidermis and ontogeny of stomata of Neotropical species of Canna (Cannaceae) was performed using light and scanning electron microscopy. Leaf outlines, presence and types of indument, epicuticular wax distribution and types, epidermal patterns, characters of the paracytic adultstomata, were analyzed here in specimens of C. ascendens, C. coccinea, C. compacta, C. fuchsina, C. glauca, C. indica, C. lineata, C. paniculata, C. tandilensis and C. variegatifolia. The characters were correlated with the habitat of the plants. Ontogeny of stomata was studied on specimens of C. coccineaand C. glauca; both perigenous and mesogenous patterns of development occur in Canna, the latter not previously described for the family. Leaf characters turn out to be diagnostic in the specific level in the studied species of the genus; using them results important and very useful when the identification ofspecies relays only on specimens in a vegetative condition. |
