Frullania Selwyniana, n. sp. 



Small, reddish brown, irregularly dichotomously branched, innovant 

 branches produced repeatedly from below the female bracts. Leaves 

 imbricate, rotund, slightly papillose, with lines of moniliform cells ; 

 lobule |th smaller than the leaf, galeate, wide mouth, erect or a little 

 divergent from the stem ; stylus wanting or very minute; cells small 

 to rather minute. Underleaves about J smaller than the leaves, 

 rather broader than the stem, oval, to a J acutely bifid, segments 

 acutate, slightly unidentate. Inflorescence monoicous, terminal on 

 short branches. Bracts 3 pairs, the innermost about twice the size of 

 the leaves, unequally lobed, complicate, lobe obtusate, irregularly 

 dentate-serrate; lobule acute with a large segment near the middle, 

 margin distantly ciliate-dentate ; second bracts similar, only smaller 

 and less dentate; third bracts subentire. Bracteole free, bifid to 

 below the middle, sinus and segments acute, margin ciliate-dentate. 

 Perianth small, subemersed, pyriform, smooth, trigonous, antical face 

 plane, postical broadly carinate, apex rostellate. Male bracts 3 pairs, 

 on short lateral branches immediately below the female, globose.

Obs. I take the pleasure of naming this distinct and beautiful 

 little species in honor of Dr. Selwyn, C.M.G., the able and distinguished 

 Director of the Geological and Natural History Department of Canada, 

 under whose auspices this list is published. It differs from Frullania 

 polysticta Lindenb in the absence of the large irregularly interposed 

 cells, in the lobule of the bracts being much smaller than the lobe
