    (Plate LXXXIX)

    The xerophytic counterpart of var. onobrychioides, occupying a lower, dryer belt along the foothills of the eastern Cordilleras. Burkart (1952, p. 253) has already correctly equated D. stenophylla with D. elegans, but cites the latter only from Sierras de San Luis and Cordoba. The cited collection from Salta (Cuesta de Muquillo, dep. La Canderlaria) is entirely typical of var. elegans, even to flower-color, noted by the collector as rosada. Burkart (1952) has pointed out that it is the close folding of the leaflets that makes them appear so narrow; but they are also smaller and more fleshy than those of var. onobrychioides.
