NEW NORTH AMERICAN MOSSES 



By Cardot 



In the Revue Bryologique for 1909, 1910 and 191 1, M. Cardot has pub- 

 lished his notes on the mosses collected in Mexico by the late Cyrus G. Pringle. 



The richness of these collections in new species and genera was " truly stupe- 

 fying" to M. Cardot as in the first 75 species identified he found 34 new species 

 and 5 new genera. Anything like a complete list of all the new species discov- 

 ered and described by M. Cardot in the Pringle collections is out of the question, 

 but among those described in these papers is one from Arizona and several 

 that had been sent me for determination by Mr. E. O. Wooton and which I 

 had passed up to M. Cardot as being unknown to me. There are still others 

 of those sent by Mr. Wooton that I think are new and have manuscript names 

 in my collection, but are waiting time and opportunity for a final decision and a 

 description. 



These mosses were picked up incidentally by Mr. Wooton and his assistants 

 in the mountains of New Mexico and their novelty and interest have given me 

 a stern resolve to visit that region myself as soon as circumstances permit, for 

 I do not believe a more fruitful field for interesting bryological discoveries exists 

 in the United States.

" Bryum Neomexicanum Card. — Synoicous. Nearest to B. intermedium 

 Brid. from which it differs in the more distinctly margined leaves with the mar- 

 gins more widely and less longly revolute, sometimes subplane, those of the sterile 

 innovations with a percurrent costa, not excurrent, and capsules with a wider 

 mouth. Stem very short. Leaves narrowly revolute in the lower half or a 

 little beyond, entire or minutely denticulate toward the apex, marginal cells 

 yellowish, linear, two- to three-ranked; costa in the leaves of the fertile stems 

 quite long excurrent. Capsule on a seta about 2 cm. long, pendent, cernuous 

 or horizontal, with a long neck, operculum apiculate. Peristome teeth yellowish 

 with 18 to 22 lamellae, cilia appendiculate. "

"Bryum longicolle Card. — Synoicous. Tufts low, 5-6 mm. in height, 

 within densely fuscous-tomentose. Leaves near the apex of the stem loosely 

 appressed, spreading when dry, somewhat flexuose, rather narrowly lanceolate- 

 acuminate; costa somewhat excurrent, cuspidate; margin strongly revolute from 

 the base to the apex, very slightly denticulate above; costa strong, red at base, 

 capsule cernuous or subhorizontal, ovate or oblong, subsymmetric, neck longer 

 than the sporangium, attenuate, sometimes curved; operculum convex, rather 

 longly and acutely apiculate; seta 2 to 2.5 cm. long. Teeth of peristome nar- 

 rowly lanceolate with 18 to 22 lamellae; membrane of inner peristome very high, 

 segments open along the keel, cilia 2 or 3, either free and appendiculate or more or 

 less coherent and nodulose. Differs from B. meeseoides Kindb. and the related 

 species by the synoicous inflorescence, the subsymmetric capsule, the long neck, 

 and the cilia often coherent, in which case they are simply nodulose. "
