Dioicous ; in large flat laxly coherent tufts, purple-black below, dull 

 green above. Stems slender, decumbent, naked at base, fastigiate- 

 branched, often with filiform small-leaved ramuli. Leaves patent and 

 erecto-patent, when dry densely imbricated, from an ovate-oblong base, 

 narrowly lineal-lingulate, obtuse, canaliculate-concave, margin erect, 

 nerve scarce prominent at back, dilated at base, vanishing in the apex, 

 cells at base rectang., 2 — 4 rows at margin quadrate and pellucid, above 

 in 2 strata, gradually minute, quadrate, firm, incrassate, at apex in 2 — 3 

 strata, rather fleshy and opake ; ramuline leaves obovate, shortly and 

 obtusely acuminate. Perich. bracts broader, sheathing. Calyptra 

 cucullate-mitriform, long-beaked ; caps, much exserted, erect or 

 suboblique, oblong or ovate, leptodermous, yellow-brown ; annulus 

 broad of 3 rows of cells, lid orange, long-beaked ; teeth orange, longish, 

 cleft to middle and lacerate, very densely articulate, erect when dry. 

 Male plants more slender, infl. terminal, bracts ovate. 

 Hab. — Alpine rocks, rare. Fr. 11 — 12. Bachnagairn, Clova [Dmmmond) ! ! 



Readily known by the obtuse leaves with incurved margins after the 

 fashion of Mollia crispula. The areolation resembles that of G. ovata, and is less 

 dryptodontoid than the other species of this section, its affinity to G. aimta is 

 however greater than to any other species. 



28. GRIMMIA ELLIPTICA {Turn.) Am.

lanceolate, suberect, muticous, margin plane incrassate, cells all sinuose, 



basal very narrow and elongate. Capsule on a thick seta, subglobose, 



castaneous, hard, lid conico-subulate. (T. L, F.)
