which Schwaegrichen has made a variety of H. stramineurri^ 

 seems to differ only in its larger size, narrower leaf, and 

 longer nerve. On the other hand, Schleicher's H. uligi- 

 nosum, which Mohr allows to be his H. Irifarium, exactly 

 corresponds with our plant. 



12. H. Schreberi-, leaves closely imbricated, nearly erect, ellip- 

 tical, apiculate, concave, entire, faintly two-nerved at the 

 base; capsule ovate, cernuous; lid conical. (TAB. XXIV.)

This species has been confounded with H. purum, but it 

 is a longer, more slender and compressed species ; the stalks 

 are always of a fine reddish tint; the leaves have a very faint 

 and short double nerve, and are of a brighter yellow-green 

 colour. 



13. H. monlllforme ; leaves closely imbricated, rotundato-ovate,j 

 obtuse, very concave, ventricose, nerveless ; capsule-ovate,)

This very curious plant, so nearly resembling in specific chaj 

 racter H. molle, is very distinct from it as well as from every! 

 other known Hi/pnum y scarcely exceeding an inch in length ; 

 and having leaves so closely imbricated and so concave as 

 to resemble Bryurn argeiiteum, or Br. Zierii. The colours 

 is a pale yellow-green. The perichaetial leaves of a reddish| 

 brown, lanceolate, nerveless. Fruitstalk about an inch long.; 

 Capsule erect ; lid conical. With us it has not been foundf 

 in fructification ; but we have fine specimens in that statej 

 from Switzerland, from which our figure and description! 

 were taken. Sir James Smith, who had never seen thel 

 capsules, was perfectly correct in stating his doubts as to his 

 plant being a Pterogonium. Wahlenberg, who first de; 

 scribed and figured this species, originally called it Lesked. 

 julacea, but changed the specific name to the scarcely less 

 applicable one here adopted. 



14. H. catenulatum ; leaves subpatent, ovate, subacuminated. 

 papillose on the back and margin^ with a very short nerve y
