276 Mr. D. Don's Descriptions of new Genera and Species 



tatis, supra concaviusculis, pruinosis. Achenia turbinate, 

 fulvescenti-villosissima. Pappus fulvus, dissimilis ; herma- 

 phroditis plumosus, mollis simus, 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 Linnaean herbarium, and which had been com- 

 municated to Linnaeus by Mutis. The figure in the Plant es 

 Equinoxiales 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 die other species I have enumerated.

 rymboso-paniculatis, involucris lanatis ; squamis exteriori-
