P. 230, Encalypta ciliata. — Since the printing of the note on 

 this species a valuable paper by Mrs. Britton has appeared in the 

 Bulletin of the Torrey Bot. Club, (Nov., 1895) containing Notes 

 on the Genus Leersia Hedw. (Encalypta Schreb.). Mrs. Britton 

 has examined the type specimens of E. Macounii Aust., and finds 

 that with a single exception (the seta is smooth, not papillose) 

 the description given by Lesquereux and James is quite correct ; 

 and she concludes from a comparison of specimens that Kindberg 

 must have had an altogether different plant under examination, 

 not the true E. Macounii ; possibly indeed E. vulgaris var. 

 pilifera, specimens of which were distributed as E. Macounii 

 (Macoun, Canadian Mosses, No. 133). This being the case, 

 Macoun and Kindberg's remarks in the Catalogue of Canadian 

 Mosses and my own criticisms upon them become irrelevant, as 

 regards E. Macounii Aust. at least, though possibly they may 

 hold good more or less with regard to the Norwegian plant 

 mentioned in my note, and if for E. Macounii Aust. we read E. 

 borealis Kindb. In any case, I think the view taken in my note 

 is confirmed, viz., that there is no sufficient evidence that two 

 distinct species have been confused under the name of E. ciliata.
