Contributions to the Bryology of Canada. 



By John Macoun. 



A catalogue of the whole flora of the Dominion of Canada, 

 by the writer has, for five years, been in course of publication 

 by the Geological and National History Survey, and has now 

 extended to Part IV., which includes the Endogens. The next 

 part of the Catalogue (Part V.) will include the ferns and their 

 allies, mosses, liverworts, and the Characeae. In connection with 

 the preparation of this part of the catalogue, I enlisted the ser- 

 vices of N. Conrad Kindberg, Ph.D., Linkoping, Sweden, who 

 nas examined the greater part of our mosses, and discovered a 

 number of species new to science, and many others new to North 

 America. At the same time I am issuing Centuries of Canadian 

 mosses for the purpose of eliciting criticism, so that when the 

 work is done it may be as near correct as possible. 



The following descriptions of species are from the pen of Dr. 

 Kindberg. The species were all detected by the writer, besides 

 many others which will be published later. 



DiCRANELLA PARVULA, Kindberg, n. sp. 



Allied to D. varia. Plants very short, densely caespitose in 

 small tufts, dark green. Leaves crenulate all around, sub-ovate ; 

 cells short, oblong-quadrate, the basal linear; costa very thick 

 and brown, excurrent, denticulate above forming at least half of 

 the acumen. Perichetial leaves denticulate above. Capsule obo- 

 vate, sub-erect or inclined without a neck, not striate; beak very 

 short and thick; annulus scarcely loosed ; teeth orange, pale at 

 ^Pex, partite, without basilar membrane, not papilose; pedicel 

 pale red-yellow; i cm. long or shorter, straight or curved only at 

 ^Pex. Dicecious.
