47. Bryum minnesotense Card, et Ther., sp. nov. (Plate 



XX., 1.) 



Dioicum, dense casspitosum. Caulis 5-10 millim. altus, 

 erectus, radiculosus, innovationibus numerosis. Folia caulina 

 madida erecto-patentia, sicca appressa, circa 2 millim. longa, 

 1-1.5 lata, ovato-lanceolata, breviter acuminata, integra, api- 

 ceve denticulis nonnullis praedita, nervo excurrente sat longe 

 cuspidata, marginibus e basi usque ad apicem revolutis ; folia 

 ramea longiora, longius acuminata, sicca subtorta ; cellulis basi- 

 laribus hyalinis, elongato-rectangulatis, mediis superioribusque 

 breviter hexagonis, valde chlorophyllosis, marginalibus line- 

 aribus, in 4 vel 5 seriebus dispositus, limbum distinctum effor- 

 mantibus. Capsula in pedicello 2-2.5 centim. longo, basi pro 

 more geniculato, nutans vel subhorizontalis, oblongo-pyriformis, 

 collo elongato attenuato siccitate plicato, operculo conico. An- 

 nulus latus. Exostomium B. -penduli, 0.36 millim. altum, 

 lamellis inferioribus anastomosatis. Endostomium adhserens, 

 membrana dimidiam partem dentium asquante, ciliis non ap- 

 pendiculatis. Sporas 18-20//. Planta mascula ignota. 



Differs from B.fiendtilum, by its narrower, longer capsule, pro- 

 vided with longer neck, longer cilia and dioecious inflorescence. 



At Granite Falls (June 13, 14). 



48. Bryum holzingeri Card, et Ther., sp. nov. (Plate 



XXI., 1.) 



Prascedenti valde affine, a quo differt : floribus synoicis, foliis 

 basi angustatis, margine minus longe revoluto, superne piano, 

 acumine longiore apice distinctius denticulato, cellulis mediis 

 circa duplo longioribus, limbo latiore, e 6 vel 7 seriebus cellu- 

 larum composito, denique capsula etiam longiore et pro longi- 

 tudine angustiore. 



The longer and narrower capsule easily distinguishes this 

 species from B. -pendulum.
