well marked in some of the characters, especially in the long pedicel and 

 the leaves reflexed on the borders. It differs from Braunia in the form 

 of the capsule, and the leaves not plicate, but papillose on the back. The 

 Hedwigiece, like the Cinclidotecie, are cladocarpous mosses, the flowers 

 being terminal on short lateral branches. Mueller places them in the 

 Hypnaccoe as species of Pllotrichum or Neckera, while Mitten refers 

 them to the Leucodonteoi. 



Tribe V. ORTHOTRICIIE^. 



Plants tufted. Stems dicliotomously fastigiate by innova-

 imbricate or cirrate-crispate when dry, terete-costate, opaque,

 tufted, glaucous or Avhitish green : leaves oblong and concave
