8 CHLORIS BOREALI-AMERICANA. 



Stated. The ovary is merely said to be three-celled by Klotzsch ; 

 and by Torrey, with closer correctness, 3-4-celled. It is some- 

 times, though rarely, five-celled, the divisions of the style varying in 

 like manner ; and, I may add, that these are quite irregular, and 

 often (as in Corema) a little incised or two-toothed. Dr. Klotzsch's 

 summary of the points in which his genus is held to differ from its 

 nearest allies will be noticed presently. 



On his return from Germany to England, in the summer of 1842, 

 Mr. Tuckerman, learning that the name which Dr. Klotzsch gave 

 to this genus had been already applied to a different plant by Mr. 

 Nuttall,* embraced the opportunity that now offered to dedicate such 

 an interesting New England plant to William Oakes, Esq. ; a bot- 

 anist whose name is " inseparably connected with the New Eng- 

 land Flora " which he has done, and is doing, so much to illustrate. 

 Mr. Tuckerman's article was published in the first volume of Hook- 

 er's London Journal of Botany, in the autumn of 1 842. He was 

 enabled to extend our knowledge of the geographical range of the 

 plant, by detecting a specimen in the Lambertian herbarium, gath- 

 ered in Newfoundland f by Mr. Cormack, which the late Professor 

 Don had misnamed " Ceratiola ericoides." He also gave a good 

 history of our knowledge of the plant up to that time ; and repro- 



* Tuckermania, Nutt. in Trans. Anier. Phil. Soc. ; Torr. and Gr. Fl. N. Amer. 

 2, p. 355 ; a showy Californian Composita. Specimens likewise exist in the late Dr. 

 Coulter's Californian collection. 



t Dr. Torrey (in Ann. Lye, I. c), having noticed that Pylaie had included Em- 

 petrum rubrum in the enumeration of his Newfoundland collection, inquires wheth- 

 er this may not be his Empetrum Conradii. Now that Newfoundland specimens of 

 the latter plant have been brought to light by Mr. Tuckerman, it becomes in- 

 teresting to answer this inquiry. An examination of Pylaie's herbarium enables me 

 to state that his " Empetrum rubrum .'' L." is not E. Conradii, but is very like the 

 Magellanic species.
