132 Mr. Brown's Observations nn the 



\n both species of Boopis. Another question respecting tlic lat- 

 ter genus is, whether its capituluni be simple, as it certainly is in 

 Acicarpha spathalata; or compound, as Jussieu's figure of Boopis 

 finthemoidcs seems to indicate. 



In the mean time, with the necessary knowledge of structure of 

 Acicarpha spathulata only, I shall venture to propose this group 

 as a distinct natural family to be placed between Compositse and 

 Dipsaceae; though upon the whole somewhat more nearly ap- 

 proaching to Compositae. This family, if my conjectures respect- 

 ing Calyccra and Boopis should be hereafter verified, may be 

 called CALYCEREiE; Acicarpha even as a generic name being 

 barely tenable, provided the original species agrees with that 

 here described : for on this supposition M. de Jussieu has mis- 

 taken the laciniae of the perianthium for paleae of the receptacle, 

 deriving the name of the genus from their form ; and has entirely 

 overlooked the real paleae, which, though they could not have 

 suggested this name, may hoAvever sanction its being retained, if 

 it be not still better to change it to Acicarpa, 



It will be attended with similar advantage to form a separate 



family of 



Brunonia, 



as a link of equal importance, connecting Composite with Good- 

 enovice, but from both of which it is in many respects very distinct. 

 As I have formerly described this genus, and made several obser- 

 vations on its principal affinities*, I shall here only state the 

 more important relations and distinctions between it and those 

 families to which it appears to me most nearly to approach. 



Brunonia agrees with Goodenovice in the remarkable indusium 

 of the stigma ; in the structure and connexion of the antherae ; in
