Mr. J. Miers on the Tribe Colletiez. 9 
by Bonpland are not to be relied on, as Kunth found them 
disproved by the analysis he made of the dried specimens ; 
the latter may therefore be accepted as the more correct. They 
correspond thus with the general features of the Colletiee, and 
the species here associated harmonize sufficiently together. 
Kunth describes the nut as containing two hard and crustaceous 
pyrene, one of which he found abortive, the other emptied by 
caries: this coating evidently corresponds with the hard crusta- 
ceous covering of the seed common to all the Colletiee. The 
genus, therefore, in the absence of perfect specimens, can only 
be characterized imperfectly, and its features will no doubt 
require some modifications whenever better evidence can be ob- 
tained ; but in the mean while, the facts already established tend 
~ to confirm its validity. Its name is derived from cxvdos, scy- 
phus, in allusion to its cup-shaped disk, after the example of 
Discaria, to which genus one of the species has been referred 
by Dr. Hooker, on account of its disk.
