leaf or more, but on the upper surface the lower 3 is usually quite

I have seen no specimens of Mr. Kirk’s var. lata, apparently distinguished by the 
broader and shorter less closely imbricate leaves. Nor are there any specimens in his 
herbarium of R. Brownit T. Kirk, previously separated from R. eximia on account of 
the linear-oblong acute leaves. . >

The conspicuous white radiating tips to the inner involucral bracts distinguish 
this at a glance from R. eximia, but in the absence of flowers it is by no means easy to 
separate the two species. The leaves of R. mammillaris, however, are shorter and 
broader, with shorter hairs which do not project so far beyond the tip of the leaf as in 
R. eximia. Beauverd figures glandular hairs as being present mixed with the ordinary 
Be on the leaves, but I do not find such in Buchanan’s specimens, which are all that 
ave seen.
