ignota. 
Hab. New Mexico, Chas. Wright (1861), in Herb. Sullivant. 
Has much the general appearance of some forms of J. colotis, 
Nees ; but that has the leaves scarcely imbricated, much less con- 
vex, less decurved, more ovate, repand and subcrenulate on the 
margin ; auricle smaller, often sublunulate, or most frequently ex- 
planate ; amphigastria rather wider and rounder; ordinary leaf- 
cells larger, the central ones much more inflated, the basal ones 
strikingly convex, ete. oe, : 
Remarkable for the cucullate apex of the upper lobe of the invo- — 
lucral leaf—The perianth is very young, but appears to be some- — 
what winged on the keels, etc., as well as on the margin. The au- — 
ricle is rather variable—often compressed, sometimes nearly touch- — 
ing the stem, at others about as distant as in F’. wolotis ; at the base 
and apex of the stem and branches it is always expanded into® — 
suboval or oblong obtuse lamina, with a largish triangular-lanceo- 
late tooth near its base. 
13.’ Frollania Sullivantia, Aust.—F. monoica, minuta, pallida, vage — 
ramosa ; foliis oblique ovato-rotundis obtusissimis convexis apice — 
decurvis cellulis crassioribus coloratis vel in medio dispersis vel 1D _ 
linea moniliforme brevi et e serie singula aut duplici et ultra exstruct® 
collectis ornatis ; auricula parviuscula obovata et obovato-rotunds ; 
cauli adproximata (vix stipitata) basi latiuscula folii margme® 
haud attingente ; amphigastriis obovato-rotundis caule parum lati- 
oribus planis margine subrepanda utrinque subunidentatis ; per 
anthio subimmerso obovato valde obtuso subtriquetro, dorso con- 
vexo, ventre breviter unicarinato utrinque leniter angulato. 
Hab, On trees in a cedar swamp near Urbana, Ohio ; detected 
by Mr. W. S. Sullivant. (Sparingly mixed with Radula obconica an 
-Phragmicoma clypeata in Muse. Alleghan. ) i 
Smaller than the smallest forms of F. Grayana, Mont.; from which . 
_ it differs in its vague ramification, flatter and more closely creeps — 
stems ; always obtuse leaves, with the bead-like cellules in the ce2- 
tre most frequently collected into an irregular patch, or when fort™- — 
ing a moniliform chain they do not run so obliquely through ihe 2 
_and consist of two or more rows (rarely of a single row) ; auricle — 
shorter and placed close to the stem and parallel with it, its bas? 
not extending to the base of the leaf, its mouth less contracted 5 
amphigastria smaller (about 14 times as wide as the stem), plane 
angular or repand, and usually with a distinct obtuse tooth on each 
_ side above the middle ; involucral leaves and amphigastria shortel 
their divisions less canaliculate ; perianth more immersed, the ape 
retuse or obtuse and crowned with a shorter apiculus, whose mout 
is slightly expandéd and strongly papulose ! inflorescence MOD@”
