80 CRTPTOGAMIA. 



placed at right angles to, and thicker than the stem. Leaves of the 

 branches erect-patent, closely imbricating, from a narrow base, oblong- 

 elliptical, cymbiform-concave, produced suddenly into a long, flexuous, 

 subdentate hair-point, nearly as long as the rest of the leaf; texture 

 membranaceous, smooth, and firm; areolation minute; cellules linear, 

 parenchymatous; those composing the alar discs numerous, larger, 

 looser, subquadrate, and of a light grayish color; costa slender, trans- 

 lucent, ceasing abruptly in the middle of the leaf. The leaves of the 

 stem and its main divisions are thinner, more distant, subappressed, 

 elongated, and gradually tapering into a more slender and flexuous 

 point. Perichaetia rare, sessile, lateral on the older branches ; arche- 

 gonia 10-12; paraphyses long, filiform, about 20-septate, and occa- 

 sionally reticulated at their base. Capsule immersed, oblong-elliptical ; 

 pedicel very short ; teeth of the peristome long, linear-subulate, orange 

 red, with perforations along the axis; cilia (injured) much shorter, 

 subulate, carinate, arising from a narrow membrane.
