XII. Masrreorena (gen. nov.), Mitt. Caulis superne simplex, inferne ramos stoloniformes et innova- 
tiones emittens, Folia amphigastriagne integra. Fructus basilaris.—The small species upon which this 
genus is proposed to be established differs in habit from Mastigobryum, the ascending stems not being 
continuous indefinitely as in that genus, but the growth of new and simple stems is renewed from the 
base, and the fructification appears to arise from the stoloniform shoots, which form the substratum of the 
plants. 
1. UW. simplex (sp. noy.), Mitt.; caulis ascendens, inferne foliis abbreviatis parvis rotundatis appressis 
sparsim dispositis stolonibus attennatis repentibus intertextus, superne inmovationibus simplicibus,

gastria parva, subquadrata, apice erosa patula; involucrum ad ramorum basin, foliis complicatis patulis 
apice denticulatis—Samoa, growing on rotten wood in a tufted manner (Powell!).—Rami 3-4 lineas longi, 
latitudine, cum foltis 3-lineares, siccitate recurvii—A small brown plant, which at first sight resembles in 
its simple stems and the form of its foliage some of the smaller species of Plagiochila.
