of its pappus being plumose through their whole length, as in 

 Craspedia, from which it is distinguished by the wantof paleee on 

 the partial receptacles, and very remarkably in habit. 



I have selected the foregoing genera as having been either pub- 

 lished under difl'erent names, or, as it appears to me, unnecessarily 

 subdivided. In this extensive class it would not be difficult to 

 point out a much greater number consisting of species impro- 

 perly united. One very remarkable case of this kind is the genus 



Galea, 



to which, as I intend to enter fully into the history and affinities 

 of its species, I shall confine myself. 



This genus was established by Linneus in the sixth edition of 

 his Genera Plantarum, where the natural character is given : but 

 the following essential character, which is still retained, appears 

 for the first time in the twelfth edition of Systema Naturae, in the 

 third section of Polygamia aequalis : 



" Receptacidum paleaceum, Pappus pilosus, Calyx imbricatus." 



The species originally referred to Galea, in the second edition 

 of Species Plantarum, are C.jamaicensis, oppositifolia, and Amellus, 

 described from specimens in Browne's Jamaica Herbarium, which 

 he had received a few years before, and incorporated with his 

 own. 



These three plants Linneus had originally referred to SantoUna*, 

 for which it seems to me rather less difficult to account than for 

 his afterwards uniting them together to form his genus Ca/ea ; 

 two of them, according to his descriptions-f-, though in reality one 

 only, being without pappus, and in other respects corresponding 

 with the generic character o^ SantoUna ; and the third, which
