Alpine mountains. Ben Bulben, Ireland, ./. T. Mackay, Esq. Scot- 

 land, especially in the Breadalbane mountains. Fr. Summer. — Here the 

 capsule is sulcated, and besides, the teeth, or cilia of the calyptra, seem 

 to be the torn or lacerated margin of the calyptra itself, more thin and 

 membranous than the rest, and hence more easily broken oft'; so that 

 the fringe often appears wanting, and is generally so figured.
