Discussion:
This species and the two following are not clearly related to any other species but they appear to be more nearly related to some of the unifoliolate species, such as S. conferta, than to the plurifoliolate ones with which they are grouped. Of the latter, perhaps S. brachyrachis is the closest relative but the much larger leaflets of S. lucida easily distinguish it. From S. pernitida the present species differs in its longer bracts and bracteoles, pubescent calyx, and in its petal shape.
