Distribution: Paraguay and northern Argentina.

We did not know this species until it was brought back by Dr. Shafer in 1917 from Paraguay, where he obtained good specimens; he also found it abundant in northern Argentina. Like many of the other species it grows in various situations, sometimes sprawling over rocks or growing on forest trees. One of his living plants fruited in the New York Botanical Garden and from this we have drawn part of our description.
