Hab. Growing with other hepaticæ, especially Lejeuneæ, at 

 Ankaratra, Madagascar; collected by Rev. M. Borgen, 1877, (Hb. 

 Kiær n. 114 p. p.). 



Obs. One of the characters assigned to the subgenus Lo- 

 pliolejeunea by its founder is „perianth 4-carinate"; he however 

 remarks in „Hep. Boliv.", Mem. Torrey Bot. Club, vol. 1, n. 3> 

 p. 122, on the perianth of Lopholejeunea Rusbyii n. sp. „facie 

 an tica subecarinata". 



In the few perianths found on Lopholejeunea lepidoscypha 

 the antical face is distinctly carinate, with the keel irregularly 

 winged like the others. 



The peculiarity of this species is in the perianth being 

 sparsely beset with small triangular leafy scales, which character 

 I have not observed in any other species. 



In Lopholejeunea Sagraena Mont. the keels of the perianth 

 are deeply laciniate, and the laciniæ toothed, but the surface is 

 quite smooth: the lobule is less convolute, and has the bracts 

 denticulate. 



Dr. Spruce, who has kindly revised my notes writes „I have 

 suggested some corrections in your description of the new Lo- 

 pholejeunea, for such it really is. In the presence of leafy scales 

 on the perianth it is almost unique among the Lejeuneæ, though
