and of the Vegetation of North America. 109 



"In the neighbourhood of Fort Franklin I have found 

 Bryum squarrosum abundant in fruit. I suspect also a new 

 species of Splachnum, with a very slender and long seta, a 

 small capsule about the size of the apophysis, and scarcely any 

 stems. There is also a small moss in abundance, agreeing 

 with Wahlenberg's description of B. pulchellum atropurpu- 

 reum, but very unlike Funck's specimen of B. pulchellum. 

 It has a smaller capsule, strongly resembling, as Wahlenberg 

 remarks, Weissia nigrita. The above list does not include 

 the mosses gathered by Drummond since we parted. When 

 added to the former collection, it raises the number of mosses 

 in these countries to upwards of 150, &c. and I trust we 

 shall detect nearly as many more by the time we meet again. 



" The Callitriche autumnalis of Wahlenberg grows in this 

 lake, and is very unlike any I have seen in Britain, either in 

 habit or fruit. It flowers under water. Captain Franklin 

 has brought from Carey's Island, at the mouth of Mac- 

 kenzie's River, some species described by you in Parry's Ap- 

 pendix, particularly the Pyrethrum ? with a large flower. I 

 have also found a curious little syngenesious plant on the 

 top of a hill in this neighbourhood. It has a leaf like a 

 Chrysanthemum, with a very obtuse or rounded terminal lobe, 

 and a single flower with a calyx like an Erigeron. It was 

 shedding its seeds when I gathered it, so that I have not seen 

 the corolla.
