The three preceding species may possibly prove to be varieties only of M. acanthocarpa, with siualltT 

 leaves, fewer pinnae, and a somewhat variable pod.

This species is evidently nearly allied to M. acanthocarpa, although the setae arc exceptional, and 

 might place it technically among the Pachycarpa, from which, however, the prickles and the flat pod 



exclude it.
