§ 199. Danthonia Faxoni, z. sp.—Culmo czspitoso valido rigido 
teretiusculo sesqui-bipedali simplici vel raro ramulo singulo subin- 
cluso ex articulatione superiore progrediente ; foliis mediocriter 
longis latiusculis circa 13-nervatis (nervibus in siccis utrinque pro- 
minulis) planis vel siccitate convolutis nudis, ligula pilosa ; panicula 
subdecomposita, spiculis (circa 15) floribus 6-7 gerentibus, glumis 
magnis flores superantibus 5-nervatis, paleis ut in D. spicata, BEAUV. 
(7-nervatis, etc.). Notch of the White Mountains, New Hampshire 
(associated with D. compressa, AusT.), Sept. 3d, 1877 (scarcely ma- 
ture), C. £. Faxon. This species is nearer to D. spicata than to any 
other known to me; but that has a more slender, always simple, 
culm, narrower, more convolute airy leaves, a more simple panicle, 
with the spikelets and glumes rather smaller. Furthermore, it ma- 
tures much earlier (by the middle of July). D. Al/eni, Aust., is 
larger, with more branched culms, broader leaves, with the nerves 
prominent only on the underside; panicle larger, palea, with the 
awn longer and less twisted when dry, glumes shorter, etc. 
With our other species, D. sericea, Nurrv., and D. compressa, 
AUST., it is not possible to confound it. C.F, Aystix.

Archidium Donnellii, 7. s9.—Proxime accedit ad 4. Ohioensem, 
Scuimp. ; differt tamen statura robustiore, colore  stramineo-vel 
lutescente-viridi, foliis tenuioribus subscariosis cellulis multum minus 
distinctis subechlorophyllosis, flore masc. in ramulo magis minusve 
elongato subgracili terminali—Hampden Countyf Va., April, 1877. 
—J. Donnell Smith. ; 
By the inflorescence this species is allied to A. Hallii, Aust. ; 
but that has the leaves much more loosely reticulated, etc. 
Bartramia radicalis, Brauv., Var. Porteri.— 2, Porteri, AUST., 
Mss.—A forma normali differt ; pedicello dimidio breviore, capsula 
siccitate globosa paulo inclinato (haud horizontali) indistinctius 
costata, membrana exteriore laxiore, peristomio dentibus solidioribus 
(semper ?) processibus longioribus? ciliis nullis? On wet rocks and’ 
banks, Western Pennsylvania, Garber in Herb., Porter; Rockdale 
(Lehigh Valley) Wolle ; Oneida, New York, Warne ; Ohio, Dr. 
Beardslee, Miss Biddlecome. 
Apparently a distinct species ; but the shape and texture of the 
leaves and the inflorescence are as in the typical 2B. radicalis from 
the South. C. F. Austin. 
§ 201. A new Cheilanthes.—I have detected. among some speci- 
mens of Cheilanthes Coopere sent out by Dr. Parry, a new species 
to which I have given the name of C. viscida—the Sticky Lip-Fern 
‘on account of the peculiar viscid glands with which the whole 
plant is so profusely covered, that, if placed in warm water, it soon 
converts it into a thick glutinous liquid. Even in the dried state 
the plants are so sticky that the fronds adhere together in a brittle 
mass, and it is extremely difficult to separate them without their 
crumbling all to pieces. I submit the following description as the 
best I am able to give from the meagre specimens at hand :
