A new variety of Anadenanthera colubrina (Leguminosae, Mimosoideae) from Argentina
Backgrounds and aims: The genus Anadenanthera is represented in Argentina by a single species, A. colubrina, with two varieties known so far, var. cebil and var. colubrina. These varieties can be clearly distinguished by the venation pattern of the leaflets. In this work, a third variety, var. glabr...

| description |
Backgrounds and aims: The genus Anadenanthera is represented in Argentina by a single species, A. colubrina, with two varieties known so far, var. cebil and var. colubrina. These varieties can be clearly distinguished by the venation pattern of the leaflets. In this work, a third variety, var. glabra, is here circumscribed by a combination of characters of its leaves and bark.
M&M: Specimens at CTES and MCNS were studied, and field observations were performed in Argentinean natural environments. The specimens were analyzed morphologically with optical and scanning electron microscopies.
Results: The new variety glabra differs from varieties cebil and colubrina, by its stems without mamelons, leaves with rachis glabrous on both surfaces or only on the abaxial surface, and leaflets with a reticulated, closed and complex venation. An illustration, photographs, a morphological comparative table and a key to the varieties, and a distribution map are provided.
Conclusions: The three varieties of Anadenanthera colubrina, var. cebil, var. colubrina and var. glabra, inhabit the Seasonally Dry Neotropical Forests of northern Argentina, showing the new variety a restricted distribution to the northeastern region of the country. |
