Macromitrium acutirarneum, Mitt. 



Macromitrium acutirarneum, Mitt, in Journ. Linn. Soc. Lond., xv. p. 62. 



Tkistan da Cunha. — Endemic. A small barren specimen — Moseley. 



Not nearly related to any known South African species, for from the areolation of its 

 leaves it is probably referable to the section Goniostoma in all the described African forms 

 of which the apex of the leaves is not mucronate. It is nearer the New Zealand 

 Macromitrium aristatum. 



Macromitrium firubriatum, Schwagr. 



Macromitrium fimbriatum, Schwagr., Suppl. ii. 1, p. 37, t. Ill; C. Mull., Synop. Muse. Frond., i.

Tristan da Cunha. Thouars. 

 Mauritius ? 



Philonotis (Bartramia) capillata, Mitt. 



Philonotis (Bartramia) capillata, Mitt, in Journ. Linn. Soc. Lond., xv. p. 62. 



Tristan da Cunha. — Endemic. On wet sandy earth — Moseley. 



The specimens of this moss have young seta?, but the capsules are unformed ; in 

 appearance it seems to be similar to the New Zealand Philonotis tenuis, Tayl., and it 

 differs from most of the numerous South African species, many of which are only yet 

 known in a barren state, by its narrow long-pointed leaves, which remain in the same 

 position when dry as they are when wet. The stout fruit-stalk seems to indicate its 

 having a capsule of the normal form of Philonotis. 



Bartramia (Plagiomela) radicosa, Mitt. 



Bartramia (Flagiomda) radicosa, Mitt, in Journ. Linn. Soc. Lond., xv. p. 62. 



Tristan dA Cunha. — Endemic. Growing on coarse sand in loose tufts — Moseley. 



Bartramia inconspicua, Mitt. 



Bartramia inconspicua, Mitt, in Journ. Linn. Soc. Lond., xv. p. 62. 



Tristan da Cunha. — Endemic. With the preceding — Moseley. 



Species of this group are numerous in South Africa, but of many the perfect fruit has 

 not been seen, so that it is impossible to assign to them the exact place in the arrangement, 

 which depends on the position and smoothness or plication of the capsule.
