Mr. Sprague read the names of a small collection of 

 cryptogamous ])lants brought by Dr. Samuel Kneeland, 

 Jr., from the Lake Superior region, as follows, namely : — 



Agaricus Orcdla, Bull. ; Lycoperdon ijyriforme, Schoeff. ; 

 Polyporus perennis, Fr., hirsutus, Fr., Cetulinus, Fr., igniarius, 

 Fr., applanatus, Pers. ; Tnbercularia pezizoidea, Scliw. ; Usnea 

 longissiyna, Ach. ; Sticta pulmonaria, Acli. ; Nechera pennata, 

 Hedw. 



These species are all common over a broad area of the 

 United States. They are mainly interesting as defining their 

 range, and showing how little change is exhibited in the 

 growths of a region extending thousands of miles. 



The President announced the resignation of Patrick 

 T. Jackson, Esq., as Trustee of the Courtis Fund. It 

 was voted to present the thanks of the Society to Mr. 

 Jackson for his able and efficient services, and Mr. James 

 M. Barnard was chosen Trustee of the Courtis Fund in 

 his place. 



December 2, 1857. 

 The President in the Chair. 



Dr. C. T. Jackson observed that a question having been raised 

 as to the variety of sorghum from which the crystallized cane 

 sugar exhibited at the last two meetings was obtained, he now 

 presented to the Society the panicle of the plant he had ope- 

 rated upon, with the ripe seed attached, which the members 

 would observe was the true Chinese variety of the sorghum, and 

 such as grows in this vicinity. 



He also presented specimens of the fructification of that 

 vai'iety of the sorghum from Caffraria, called there the Im- 

 phee, which is suited only to warm climates, and will not 

 ripen in New England, but which, in warm seasons, ripens in 

 the Southern States.
