 the former, and its total difference in habit. It agrees with E. ciliaris 

 in the character of its foliage, but differs from that plant by having 

 anthers awned. Gathered by the author on Craigha Moira, Conna- 

 mara, Ireland, in August, 1835. Mr. Mc Calla, of Roundstone, 

 directed his attention to it, as being, perhaps, a new British heath.

Observations on the Species of Fedia. By Joseph Woods, 

 Esq., F. L. S. 



This genus was originally made from the varieties of the Linnean 

 species, Valeriana locusta, being separated from Valeriana by habit 

 as well as by the want of a feathery crown to the seed. The name 

 comes from Hcedus, or Foedus, a kid, and was introduced by Adanson, 

 although not applied by him to this genus. DecandoUe divides it 

 into four divisions. 1. Locusta: with one or two empty cells and 

 a gibbous corky or spongy mass at the back of the fertile one. 2. 

 Psilocoelae : the two empty cells, each reduced to a hollow nerve. 



3. Platycoelae : two empty cells, nearly as large as the fertile ones. 



4. Selenocoelae : section of the fruit, crescent shaped, with two empty 

 cells. 



Mr. Woods suggests that the European species may be divided 

 as follows: A. Flowers ringent. 1. F. Cornucopice: B. flowers 

 nearly regular: A. fruit with a corky mass at the back of the seed. 

 2. F. olitoria. 3. F. gibbosa b. section of the fruit crescent 

 shaped, two barren cells, a. F. turgida. 5. F. carinata. 6. F. 

 platyloba : C. barren cells two, hardly touching in the middle ; di- 

 visions of the calyxhooked ; flowers in globular heads ; upper leaves
