 green tufts, blackish at base, radiculose. Leaves at base broadly oval 

 or suborbicular, acute and plane at margin ; comal leaves much less 

 acuminate, recurved at apex, mucronate with the excurrent nerve, upper- 

 most lanceolate, the margin with a limb of 5 6 rows of very long narrow 

 cells ; areolation firm, close and opaque, the cells rhomboid ; capsule 

 regular, oval, pendent, brown ; lid small, convex, with a small acute 

 mamilla ; teeth of peristome gradually acuminate, orange, papillose in 

 upper ^, the ventral surface hyaline, of many close joints without accessory 

 partitions ; endostome adherent.

 and in the Aland islands by the energetic collector Bomansson. I have I 

 Mr. Dixon for the opportunity of figuring it.
