Native. Pratal or Sylvatical ? This very local species, 

 found by so few English botanists, has been long recorded 

 for the single county of Wilts ; and Mr. C. C. Babington 

 informs me that he has a specimen from the original locality, 

 near Boyton, gathered by the Rev. J. Downes. In the first 

 volume of the Phytologist, p. 780, Mr. Westcombe pub- 

 lished a second habitat, " between St. Donat's and Dun- 

 raven, Glamorganshire." These are the only two localities, 

 of which I am aware, recorded expressly for C. tuberosus. 

 But last year I was indebted to Mr. S. P. Woodward for a 

 set of puzzling specimens, which that gentleman first con- 

 ceived to belong to C. Forsteri, and afterwards thought that 

 they might be very luxuriant examples of C. pratensis and 

 C. acaulis. For my own part, I still hesitate between 

 adopting the opinion of Mr. Woodward or referring the 

 specimens to C. tuberosus ; and in this uncertainty, they 

 are temporarily distinguished by the name of their disco- 

 verer and collector. The habitat is thus given by Mr.
