The sterile plant agrees perfectly with authentic European specimens. The 

 fruit appears to have been collected now for the first time, and is extremely 

 rare in our locality. The leaves on the horizontal and fertile stems are crisped 

 and wavy, much as in most Fossombronice. The former often bear little balls 

 of green gemmae on the apices of their lobes, and are subhori/.ontal and fre- 

 quently imbricated, while the latter, towards the perianth, are usually 1 — 3 lines 

 apart, subopposite and erect. The leaves, particularly on the erect stems, are 

 about as often two as three lobed, and can hardly be said to be complicate, or 

 either saccate at the base. The stem is usually very conspicuous on account 

 of its blackish color. The perianth is whitish or membranaceous above, and 

 at first subtriquetrous. 



JUNGERMAX.VIA WaLLROTHIANA, NcCS. 



"Nigricans, minutissima. Caule repente, adscendente, subsimplici vel 

 innovante ramoso, vix 5 — 1 linea longo, valde radiculoso ; radicibus crassis 

 papilliformibusque. Foliis diametro caulis latioribus, amplectentibus, firmis. 

 ovato-quadratis, arete imbricatis, semiverticalibus, concavis, sursuni conni- 

 ventibus, emarginato-bidentatis ; sinu vel obtuso in foliis inferioribus, vel 

 acuto in foliis superioribus ; dentibus obtusiusculis integerrimis; margine 

 pellucidis ; areolatione distincte, cellulis ovato polygonis, olivaceis, margine 

 tantum pellucidis. Foliis involucralibus majoribus, erectis, tridentatis, undato- 

 plicatis, basi connatis ; deniibus acutis vel obtusis. Perianthio ovali-cylindrico, 

 superne contracto, plicato ; ore subdentato, pellucido, inferne rubello."

On coarse sand, on the slopes of the White Mountains of New Hampshire, 

 Oakes. 



A very minute species, but more than twice the size of./. SulUvantii, from 

 which it is also distinguished by its entire leaves, papillaeform rootlets, and 

 different perianth. Leaves round-ovate, thickish,^-bifid, the lobes triangular- 

 ovate, acute; cellules irregularly angled, subquadrate or oval, rather uniform, 

 largish for the size of the leaf (about ten across its widest part), opaque, with 

 broad hyaline spaces between. Apex of the lobes hyaline, often slightly 

 eroded on the margin. Color dark or olive-brown. Perianth terminal, 

 subpyramidal, cleft about one-third way into about six sublinear truncate 

 lobes, the apex white and pellucid, the middle and base dark brownish-red ; 

 the mouth crenulate by the protrusjon of the ends of the very large, oblong 

 cells, of which the upper portion of the perianth is composed. Leaves of the 

 involucre enlarged, entire on the margin.
