Alpine rivulets, in Scotland. Mr. Dickson. Fr. ? — I am not 



aware that any one, except Mr. Dickson, has seen this plant growing in 

 Britain"; nor do I know in what particular part of Scotland he gathered 

 it. Dillenius' specimens were from Pennsylvania : and beautiful indi- 

 viduals were gathered by Mr. Drummond in North America, during Capt. 

 Franklin's 2d. Journey, and published by him in his valuable Musci 

 Americani, v. 2. n. 234.

 Moist banks, in woods and among rocks. Fr. Feb. — Stems procum- 

 bent, 2—4 inches long, slightly branched, plane. Leaves arranged on

 jagged at the base.

 Dec. — Much smaller than the last in every part and readily recog- 

 nised by that circumstance, as well as by the deep green colour of the 

 leaves, their smaller reticulations and the 2 long nerves.

 cated on all sides erect oblongo-lanceolate, nerve reaching nearly 

 to the point, calyptra fimbriated at the base. — Baltonia splach-
