106 ON NEW MOSSES. 



The author, with lively satisfaction, acknowledges his indebtedness to the eminent 

 bryologist, Leo Lesquereux, Esq., of Columbus, Ohio, for having authenticated most of 

 the plants reported in this catalogue. 



SPHAGNUM, Dill. 



S. COMPACTUM, Brid. Var. rigidum, Mull. Var. humile, Schimp. 



Hab. Quakerbridge and other localities in New Jersey. These varieties have hitherto been reported as occur- 

 ring solely in the Southern States. 



S. CYCLOPHYLLUM, Suttlv. and Lesqx. 



Hob. Batsto, near Quakerbridge, New Jersey. 



S. SEDOIDES, Brid. 



Hob. Ethan's Pond, Willey Mountain, New Hampshire, and Quakerbridge, New Jersey. 



S. Pl'L^SII, Brid. 



Hob. Same localities as the preceding. All heretofore considered of Southern origin. 



S. FIMBBIATUM, Wils. 



Hub. Pinkham Notch, near the Glen House, White Mountains, New Hampshire. 



Our plant has the stem-leaves less fimbriated than the figured species of Schimper, but 

 corresponding in every other character. Drummond collected this species in British 

 America. 



S. CUSPIDATUM. Var. fluitans, Schimp. 

 Bab. Batsto, New Jersey. 



PHASCUM, Linn. 

 EPHEMERUM, Ilumpe. 



E. SYNOTCUM. Sp. nov. Caule ceespitoso, brevi, tenero, basi radiculis in plantis junioribus byssoideis instructo. 

 Foliis inferioribus brevibus, ovato-lanceolatis, superioribus longioribus, lanceolatis vel lineari-lanceolatis, margine 

 integris vel apice areolis exeuntibus subdentatis, enervis, laxe areolatis ; perichEetialibus conformibus vix longioribus. 

 Inflorescentia hermaphrodita; archegoniis antheridiisque e paraphysatis in eodem perichsetio plurimis. Capsulis 

 globosis, vel singulis, vel binis quandoque ternis in eodem perichastio, subsessilibus vel brevissime pedicellatis, 

 Calyptra basi vix dilatata agglutinata longe rostellata. Sporis magnis papillosis. 



By the leaves, the general outline of the plant, the areolation, the form of the capsule, 

 and the spores, this species is a true Ephemerum. It differs, however, from all the species 

 of this genus by the hermaphrodite inflorescence. It has obscurely pro-embryonal fila- 

 ments, although the filaments attached to the roots are, when young, truly byssoid. 

 This species is very remarkable for the number of its capsules, generally two, sometimes 

 three, in the same perichsetium. It does not compare with any described species. By
