Variante cambial en tallos de Ipomoea (Convolvulaceae) nativas de Argentina. Delbón, Natalia Sánchez, Agustina Cosa, María Teresa Ipomoea enredaderas variante cambial cámbium. Cambial variant in stems of Ipomoea (Convolvulaceae) native from Argentine. Ipomoea is a diverse and complex genus, composed of herbaceous plants, woody lianas and vines, and a small group of shrubs and trees. It is noteworthy that all species studied previously presented different types of cambial variant in their stems, regardless of habit, except two taxa that showed normal secondary growth, a vine and a tree. Therefore, in this paper we study three vines natives from Argentina, Ipomoea cairica, I. purpurea and I. rubriflora, and I. carnea ssp. fistulosa, a tree with normal growth, in order to compare the development of their stems and provide useful information to elucidate their phylogenetic relationships.The four species studied showed the same ontogeny and anatomy of their stems with primary growth, which would support its narrow phylogenetic relationships. On the other hand, the vines had only twotypes of cambial variant, the lobed pattern and supernumerary cambium. We can infer that the type of secondary growth and cambial variant types would not be directly related to the habit; however, otherwood features can be considered as the proportion of parenchymal tissue and characteristics of the vessels. Ipomoea es un género diversificado y complejo, compuesto por herbáceas, lianas y enredaderas leñosas, y un pequeño grupo de arbustos y árboles. Llama la atención que todas las especies estudiadas anteriormente presentaron diferentes tipos de variante cambial en sus tallos, independientemente del modo de vida, excepto dos taxones con crecimiento secundario normal, una liana y un árbol. Por ello, en el presente trabajo se planteó el estudio de tres enredaderas nativas de Argentina, Ipomoea cairica, I. purpurea e I. rubriflora, y de I. carnea ssp. fistulosa, árbol con crecimientonormal, con el fin de comparar el desarrollo de sus tallos y aportar datos de interés para dilucidar sus relaciones filogenéticas. Las cuatro especies estudiadas presentaron igual ontogenia y anatomía desus tallos con crecimiento primario, lo que apoyaría sus estrechas relaciones filogenéticas. Por otro lado, las enredaderas presentaron sólo dos tipos de variante cambial, el patrón lobado y el de cámbiumsupernumerario. Se puede inferir que en Ipomoea el tipo de crecimiento secundario, así como los tipos de variante cambial, no estarían directamente relacionados con el hábito; sin embargo, otras características del leño pueden ponerse a consideración como la proporción de tejido parenquimático y características de los vasos.
