288 OBSERVATIONS ON THE NATURAL FAMILY 



to what I have supposed led him to separate all the three 

 from Santolina. It is remarkable, however, that not one of 

 these three original species of Galea corresponds with his 

 character of the genus ; and that they in reality belong 

 to three very distinct genera, on principles which, I conceive, 

 Linnaeus himself would have admitted. 



The flrst species, Calea jamaicensis, is the only one that 

 even seems to agree with the generic character, in having 

 pappus which at first sight (to the naked eye at least) 

 might appear simply capillary, but which on a closer 

 examination proves to be of a very different and nearly 

 peculiar structure. Of this species I have seen only one 

 authentic specimen, received from Browne by Ehret, and 

 now in Sir Joseph Banks's Herbarium. The specimen in 

 question, though incomplete, evidently belongs to the same 

 species with " Conyza fruticosa cisti odore, floribus pal- 

 lide purpureis, summitatibus ramulorum insidentibus/' of 

 Sloane, 1 of which I have examined the original very perfect 

 specimens in his Herbarium, preserved in the British 

 Museum, 2 and am satisfied that its pappus is of the same 

 structure as that of Calea corclifolia of Swartz, who has w r ell 

 described it, but who has at the same time given a different 

 io9] account of that of C. jamaicensis? These two plants are 

 the only published species of this genus, for which the name 

 of Calea should be retained, and which may be distin- 

 guished by the following characters : 



Calea.
