Extremely close to this, if not conspecific with it, is a plant of Balansa's (no. 2436), 
collected at Concepcion, in Northern Paraguay, and described as a shrub 2-3 metres 
high, with fleshy brown fruit; but, seeing that Balansa's specimen is without flowers, 
the question as to specific identity cannot be answered. There is also in the Herbarium 
at Kew a small specimen, gathered by Tweedie at Buenos Aires, which, on superficial 
examination, closely resembles the Matto Grosso plant, but of which I can find no 
description. [Argentina.]
