TENERIFFE MOSSES 



what misunderstood. I have examined the type of B. Tenerijfm'va. 

 Hampe's lierbarium at the British Museum, and find it a plant of 

 quite a different habit, with long, lax innovations bearing flaccid, 

 flexuose leaves, as described by Hampe, whose note, " B. capillari 

 proxima, sed foliis lato-limbatis superne dentibus aciculiformibus 

 seu ciliformibus nonnullis longioribus vel brevioribus primo mo- 

 mento distinctum," quite removes it from any very close affinity 

 with the present plant. The stout nerve, purple at the base, and 

 the teretely imbricated branches with the leaves erect and ap- 

 pressed when dry, give the plant a very different appearance 

 from any form of B. cainUare or the allied species. Bryum clava- 

 tulum Card. & Dixon from the Azores has somewhat the same 

 habit, but the leaf structure is quite different. From B. obconicum 

 it differs in the stout nerve, wider, more obtuse, densely imbri- 

 cated leaves, &c. 



The peristome characters also may have some value. The 

 capsules were nearly all operculate, but mostly fairly well ripened. 

 In the two cases where the lid had already become partially 

 separated from the capsule, I found the annulus entirely adherent 

 to the rim of the hd, and showing no signs of spHtting up or 

 separation under pressure or after heating in water ; but I can 

 scarcely think this to be a normal character.

Aulacomnium androgynum Schwaeg. Eock-boring made in 

 search of water, Eisco del Frayle, above Vilaflor (no. 31). The 

 usual gemmiferous form. Genus and species new to the Atlantic 

 Islands. 



Bartratnia stricta Brid. Barrancos above Guimar (no. 2), c.fr. 



Philonotis fontanel Brid. By watercourse, Vilaflor (no. 33).

 de Guimar (no. 54). 



Leptodon longisetus var. flagellifer Mont. Evergreen woods, 

 Teno Mountains (no. 59 a). This variety is totally different in its 

 habit and size from the type of L. longisetus (which differs little 

 in its vegetative characters from L. Smithh), and it is difficult to 

 realize that it belongs to that species ; the stems are four to five 

 inches long, with long, often tiagelliform branches, resembling 

 slender forms of Neckem turgida or N. mediterranea in general 

 appearance.
