276 Mr.D. Dow's Descriptions of new Genera and Species 
tatis, suprà concaviusculis, pruinosis. Achenia turbinata, 
fulvescenti-villosissima. Pappus fulvus, dissimilis; herma- 
phroditis plumosus, mollissimus, radiis copiosis (20—25) 
basi connatis ; masculis setosus, radiis 20, subulato-setaceis, 
recurvatis, hirsutis, basi callosis, connatis. 
The above description is taken from the original sample pre- 
served in the Linnzan herbarium, and which had been com- 
municated to Linneus by Mutis. The figure in the Plantes 
Equinoviales is a good representation of this species; but I am 
in doubt respecting that of Lamarck, which appears to ap- 
proach nearer to the following. It is most probable that B. spi- 
nosa is peculiar to New Granada, and that the Peruvian plant 
said to be the same, is really distinct, and that it belongs to one 
of the other species I have enumerated.
