tered, and in this region sterile. The fruit is also rare in England. 

 The rosettes are sometimes quite small, and scattered in among 

 other mosses, though they may reach half an inch across, bearing 

 as many as five capsules on stout, erect pedicels, the capsules 

 often one-quarter of an inch in length, and slightly curved- 

 Kindberg has separated oiT B. Ontariense as a species, but the 

 differences which he notes are seen also in European specimens, 

 according to Cardot, who believes it to be simply a form of B. 

 roseum. Certainly there are great differences in specimens ac- 

 cording to habitat. The species has a wide range, but is most 

 common in the East, from New Brunswick to Ontario, and Maine 

 to Virginia, also in California. It grows in woods, on rocks and 

 logs and at the base of trees, in rich, loamy soil, and a few 

 depauperate specimens have been found in Bronx Park. Mats of 

 it, brought down from the Adirondacks, have suffered from our 

 hot, dry summers. In Mexico and South America there are sev- 

 eral closely allied species, and the genus seems to reach its maxi- 

 mum development in Japan, where one species grows which is 

 six inches in height, and has rosettes an inch across.

CLAOPODIUM PELLUCINERVE (Mitt.) 



AMONG a number of interesting mosses brought back from the 

 Yukon Territory by Mr. R. S. Williams is Claopodiuin pel- 

 lucinerve. Although destitute of fruit, yet when compared 

 with a specimen of this species kindly sent to me by Dr. Mitten, it 

 is found to be unquestionably the same. C. pellucinerve was origi- 

 nally described as Leskea in Mitt. Muse. Ind. Or. and was col- 

 lected at Simla, North India. Comparing it with the recognized 

 North American Claopodia* it is found to be somewhat intermedi- 

 ate between C. Whippleanum and C Bolanderi, differing from 

 the former in not having the leaves of the terminal branches two 

 ranked, the stem leaves entire and not margined by a row of cur- 

 vilinear cells, the median cells oval rhombic, distinctly studded 

 by minute, bead-like papillae, and the subfiliform acumen hyaline 

 pointed. From C. Bolanderi \\. differs in being smaller, the stem 

 leaves 0.25-0.3501111. wide and 0.5-0.70101. long, the median cells 

 oval-rhombic, not quadrate hexagonal as in that species and in the 

 more numerous and distinct papilht. Dr. Mitten informs me that 

 the capsule of C. pellucinerve is exactly the same as that of C. 

 Whippleanum.— G. N. Best, Rosemoni, N. J.
