this species is similar to S. kumile Schpr., as described and 
figured in Sullivants Icones, p. 5, tab. 3. Its size is a little 
smaller, and the capsules are longer pedicelled and also 
smaller. The absence of pores in the areolae, and the im- 
marginate branch leaves, truncate-dentate at the apex, are 
also characters which separate this species from S. humile 
and related congeners. » 
2, Archidium longifolium Lesq. et James. — Florida (Gar- 
ber). « Differt ab 4. alternifolio planta tenuiore ; foliis an- 
gustioribus, longioribus, anguste e lanceolato subulatis ; 
costa superiorum in subulam laevem excedente. Antheri- 
dia 2 in foliorum perichaetialum axillis. » 
3, Bruchia Sullivanti Austin (— B. fleæuosa Schwgr. in 
Sulliv., Icones Musc., p. 22, t. 13). — South-Carolina. —- 
Flores monoici, capsula brevius pedicellata, brevior. — The 
true Bruchia flexuosa Schwgr. is bisexual ! 
4, Bruchia brevicollis Lesq. et James. — South-Carolina 
(Ravenel). Differt a B. Sullivanti planta minoregraciliore; fo- 
liis pro ratione longioribus, supra basin ad apicem angus- 
tioribus, louge subulatis, subula tota e costa dilatata consti- 
tuta ; calyptra majore infra sporangium producta ; collo 
y breviore angustiore ; pedicello recto ; sporis majori- 
us. 
5, Weisia longiseta Lesq. et James. — Florida (W. L. Fors- 
ter). À W. viridula proxima differt : inflorescentia dioica, 
capsula in pedicello longo subunciali pertenui subflexuoso 
lutescente subcernua, etc. 
6, Weisia Wolfii Lesq. et James. — Canton, Jinois (L. 
Wolf). Differt a W. longiseta foliis angustioribus pro ratione 
longioribus, parte superiore fere exacte tubulosis, humidi- 
tate arcuato-recurvis ; capsula in pedicello breviore lon- 
giore oblongo-cylindrica, haud sulcata nec sub ore coarc- 
tata ; peristomii dentibus truncatis. 
7, Ptychomitrium (Notarisia) pygmaeum Lesq. et James. 
— Near the Neosho River, Kansas, and at Bolivar, Missouir 
(E. Hall). — « This species, the smallest of the genus, is 
_distinguished by its minute size, the structure ofits leaves 
and the marked neck of the capsule, extinding one third its 
length. » 
8, Fissidens Garberi Lesq. et James. -- On the bark of 
trees, Florida (Garber). —— « In the shape of its leaves this 
species ressembles F. obtusifolius Wils., but it is smaller, 
= the capsule narrower, the operculum beaked, and the areo- 
= lation rather quadrate than angular-rounded. » de 3

cies is like the small forms of F. adiantoides Hedw., t0
