Bentham equated M. oligacantha with M. distachya, of which he considered it merely a strongly armed form. The position of the cauline aculei immediately below the nodes and not on the intemodes is a distinctive quality of all specimens seen. Similarly situated aculei are common, however, in M. polyantha, which could be considered an element of an extended M. distachya.
