HYPNUM. 269 



Since the publication of Hooker^s ' Muscologia Britan- 

 nica^ and ' British Flora/ vol. ii., several interesting addi- 

 tions have been made to various genera of the family, by 

 discoveries of species and varieties hitherto undescribed as 

 British. The most of these are recorded in the preceding 

 pages, with their allied forms; but it has been thought 

 desirable, from the size of the genus Hijpnum, to record, as 

 a supplement, a few of the most marked forms recently dis- 

 covered, and ranked as species by Mr. Wilson and other 

 careful observers. 



1. Hypnum androgynum, Wils. {Androgynous Feather 

 Moss.) Stem creeping ; branches short, pinnately branched, 

 somewhat robust and obtuse, cordato-ovate at the base, 

 broadly lanceolate-acuminate, plano-concave, minutely ser- 

 rate on the margin, glossy ; perichsetial leaves pale, squarrose, 

 the footstalk rough; capsule incurvo-oblong, subcylindrical, 

 with long operculum. Hypnum Starkii, MiilL Sj/n. pt. 2.

 Mitten, in 1848. Only two localities are enumerated on 

 the continent.
