This species is very nearly allied to Trichostomum funale 

 of Schwaegrichen, but differs from it in its smaller size, 

 broader and elliptical leaves, which are more suddenly acu- 

 minate. The teeth of the peristome are generally perforate 

 of deeply cleft, more rarely entire ; hence it has by some 

 authors been put among the Dicrana, and by others among 

 the Trichosioma.

5. Gr. Daviesii; stems short; leaves lanceolate- acuminate, ca- 



rinate, entire, much crisped when dry, their margins re- 

 curved ; those of the perichsetium broad and convolute ; cap- 

 sule turbinate, lid rostrate. (TAB. XIII.)

This plant has many characters in common with Tricho- 

 stomum ellipticum\ as the shape of the leaves, which are 

 however much longer and more crisped when dry ; of the 

 capsule, but which is more truncate; and of the peristome, 

 which having its teeth generally split in T. ellipticum are 

 in Gr. Daviesii always entire. The general colour of the 

 present plant is brownish like that of Gr. maritima, with 

 which it is frequently found growing, 



6. Gr. ovata; stems slightly branched; leaves lanceolato-subu- 



late, gradually produced into long, diaphanous, hair-like 

 points, their margins incurved ; capsule ovate ; teeth of the pe- 

 ristome often perforated and split; lid rostrate. (TAB. XIII.)

HAB. Alpine rocks. 



We do not hesitate to make the Gr. oltusa of Schwaeg- 

 richen a synonym to this, since we have Mougeot and 

 Nestler's specimens, which precisely accord with our plant, 

 as indeed does Schwaegr ichen's figure. From Gr. pulvi- 

 nata it differs in not having the fruitstalks curved at any 

 time, in its smooth capsule, in its narrow and gradually acu- 

 minated leaves, and in its place of growth, this being al- 

 together alpine.
