This endemic species was originally described by Bentham as Desmodium 

 sccurifoime, and placed by him in the section Podocarpium, stating that the 

 articulations of the pods are usually solitary; a rather complete series of speci- 

 mens shows that the pods are always reduced to a single joint, and that in 

 a number of flowers examined, from different specimens, the ovaries never show 

 traces of more than one joint, or more than one ovule. It has the general 

 appearance of various species of Desmodium of the section Podocarpium, and 

 has undoubtedly been derived from the section; it is, however, distinguishable 

 from all species of Desmodium by its 1-seeded, nonarticulated pods, 1-ovuled 

 ovaries, and narrowly oblong seeds, and I consider it to be generically distinct. 



While Monarthrocarpus' rasij not be distinguished from Desmodium by stronger 

 characters than some of the sections of that genus, such as Dendrolohhnn, Phyllo- 

 dium, etc., it has been considered expedient to propose for it generic rank, although 

 logically, it should, perhaps be treated only as a section. As noted in the introduc- 

 tion to this paper, for purposes of comparison, genera have been retained as 

 defined by Bentham and Hooker in their Genera Plantarum, or by Taubert in 

 the Natiirlichen Pflanzenfamilien, and hence I have not followed some recent 

 botanists in raising various sections or subgenera of Desmodium, Cassia, etc., to 

 generic rank, although in a number of cases I have no doubt but that some of the 

 sections or subgenera are worthy of being so treated.
