29. Stereocaulon denudatum, variety digilalum, Fr. Pico, 

 at an elevation of 7600 feet. 



30. Stereocaulon condensatum, and 



31. Ster. nanum. From a Misterio, a wild region extend- 

 ing over many miles at the north end of the island, being the 

 track of the last eruption, (A. D. 1672) proceeding from the 

 Pico de Fogo in two directions toward the sea. The black rocks 

 are entirely covered with gray, crisp lichen, a few other species, 

 which I send, being sparingly intermixed. In sheltered spots, 

 mosses and ferns are beginning to show themselves, and fig 

 trees and other bushes sometimes occur ; but the prevailing 

 aspect is of a grey hoar-frost — or sometimes in the sunlight 

 like a hillside covered with mountain laurel {Kalmia lalifolia). 

 It is always marked by a definite line from the green country 

 each side. The stone walls which intersect it here and there, 

 built of the same lava rock, and whose age I could not learn. 

 are covered equally densely with the same growth, showing it 

 to be comparatively recent. Such a region is called by the 

 Portuguese a Misterio or Mystery.
