HAB.' On Ben High in the Scottish Highlands, Mr .Dick- 

 son. Very rare. 



The figure and description in English Botany represent the 

 leaf of this plant acute, contrary to our observations upon 

 Mr. Dickson's specimens. Weissia splachnoides and Gym- 

 nostomum Griffithianum, which have the habit of a Splach- 

 num, and from their obtuse leaves might by a casual ob- 

 server be mistaken for this species, differ; the former in the 

 greater length of the fruitstalks and ligulate leaves, and the 

 latter in the much broader, obovato-rotundate leaves, in the 

 want of a real apophysis, and in the thickened fruitstalk, 

 to say nothing of the characters of the respective genera. 



In S. Frcelichianum the steins scarcely ever exceed half 

 an inch in length,, and the fruitstalks are about twice as 

 long. 



10. CONOSTOMUM. 



GEN. CHAR. Fruitstalks terminal ; Peristome single, 

 of 16 equidistant teeth, all united at their sum- 

 mits ; Calyptra dimidiate. (TAB. I.) 



This curious genus, which was first established by Swartz in 

 Schrader's Journal, approaches in habit, as Wahlenberg justly ob- 

 serves, to Bar tramia font ana; and the exotic species named 

 C. australe by Swartz has actually been described by Bridel 

 under the name of Bartramia pentasticha. 



1. C. loreale; sterns rather short; leaves lanceolate, acuminated, 

 carinated, slightly toothed. (TAB. X.)

HAB. The summits of the highest of the Scottish moun- 

 tains, especially in the Breadalbane district. 



The leaves do not appear to us by any means to give the 

 stems a regularly tetragonous appearance, as Dickson's name 

 implies, nor to be quincjuefarious, according to Sir 4ames
