scabrid at the base, slightly narrowed towards the mouth.

19. G. arcxiatus, n.s. 



Plants dioecious, growing in dense tufts, lin. to 2in. high, 

 yellow above, brown below. Stems nearly simple, slightly 

 gemmiform at the apex. Branches aggregated, arising from 

 the apex ; one, and sometimes two, being innovations con- 

 tinuing the stem, the others being short branches bearing the 

 fruit, variable in number. Leaves inserted all round the stem, 

 imbricating, straight erecto-patent ; middle ones small, linear- 

 lanceolate, tapering into a slender hair-point, hyaline and 

 slightly toothed at the apex ; upper small, shortly ovate- 

 lanceolate, tapered into a short point, hyaline at the toothed 

 apex. Nerve broad, lamellate. Leaves erect when dry. 

 Areola small, linear. Fruiting -branch leaves : lower very 

 small ; middle ones large, shortly ovate, tapering into a 

 slender hair-point ; upper larger, but similar in outline, 

 hyaline, and toothed at the apex ; perichaetial longest, cylin- 

 dric, tapering into a long slender hair-point, hyaline, slightly 

 toothed at the apex. Fruit terminal, solitary. Fruitstalk 

 hygrometric from the middle upwards, flexuous and decurved 

 when moist, erect and spirally twisted when dry. Capsule 

 small, oblique, cylindric. Operculum oblique, narrow, subu- 

 late, half the length of the capsule. Peristome imperfect, 

 single, 16, united at the base. Calyptra cucullate, fringed at 

 the base with cilia.

20. C. otaramaii, n.s. 



Plants dioecious, growing in dense patches, lin. to 2iin. 

 high, green above, brown below. Stems simple or dichoto- 

 mously branched, gemmiform at the apex. Branches aggre- 

 gated, arising from the apex ; one or two of them being inno- 

 vations continuing the stem, the others being short branches 

 bearing the fruit. Leaves inserted all round the stem, imbri- 

 cating, erecto-patent or spreading, semi-convolute ; middle 

 stem leaves subulate, tapered into a hair-point, hyaline at 

 the apex, and slightly toothed ; upper, shortly oblong-lanceo- 

 late, tapering into a long hair-point, hyaline, and slightly 

 toothed at the apex. Nerve broad, lamellate. Leaves flexuous 

 when dry. Areola small, oblong. Fruiting -branch leaves : 

 lower and middle shorter, oblong-lanceolate, tapered into a 

 long hair-point, hyaline, and slightly toothed ; upper, oblong.
