The factual accuracy of this description or the file name is disputed.
Reason: I do not see pubescence in calyx or ask for it, so S. aphylla is not. By distribution and branches, it is not S. pachyrrhiza var. pendula. Also, due to the fact that it was found in a mountain range and the branches very zigzagging, it is surely this other species. [This is Google Translation, Spanish text is here ]
