tiones emittens. Folia amphigastriaque 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 
pes and the fructification appears to arise from the stoloniform shoots, which form the substratum of the 
plants. 
1. M. simplex (sp. nov.), Mitt. ; caulis ascendens, inferne foliis abbreviatis parvis rotundatis appressis 
sparsim dispositis stolonibus attenuatis repentibus intertextus, superne innovationibus simplicibus,

apice denticulatis.—Samoa, growing on rotten wood in a tufted manner (Powell !).—Rami 3-4 lineas longi, 
latitudine, eum foliis 2-lineares, siccitate recurvi.—A small brown plant, which at first sight resembles in
