at least two sides of the stem, and some of them below the two outer inrolu- 

 cral leaves, whi^ih are simply retuse at the apex and nearly entire, while the 

 two inner ones are unequally bilobed and lacerate- toothed. 



JONUERMANNIA BFFORMIS, Aust. 



J. caule dense caspitoso ralde intricato e ventre innovante pluries ramoso, 

 valde radiculoso, radiculis tenui^simis longissimis subfasciculatis supremis 

 nonnuUo rubris ; foliis succubis vix imbricatis subcomplanatis oblique semi- 

 circularibus vel late ovatis tenuibus, margine dorsali decurrentibus apice 

 integris retusisve, rete e cellulis magnis subrotundis hyalinis intersliciis . 

 angustissimis instnicto, surculorum foliis dimidio minoribus ovatis obovatisve 

 valde obtusis vix decurreutibus ; amphigastriis nullis ; fructu ignoto. — Hep. 

 Bor. Avier. Exsic. i?ied., No. 2G. 



On wet rocks, at the Delaware Water Gap, New Jersey, 1867. 



Remarkable for the closely entangled and matted stems and surculi, and 

 for the leaves of two forms. The texture of the leaves is much as in Oali/po- 

 geia Trichomams. 



JUNGERMANNIA FOSSOMBRONIOIDES, AuSt. 



J. caule dense casspitoso adscendente (radicibus purpureis subincrassatis) 

 valde radiculoso ; foliis disticho-subverticalibus arete imbricatis orbiculatis, 

 margine undulato-repandis, apice brevi uniplicatis leniter emarginatis patulo- 

 subrecurvis, basi subcordatis caulem amplcctentibus subventricosis radiculo- 

 sis, involucralibus conformibus cum perianthio alte connatis ; perianthio 

 maximo longiuscule exserto subcampanulato sex — decemplicato, ore hiante 

 profunde laciniato, laciniis integerrimis ; calyptra omnino violacea ; capsula 

 ovali. — Hep. Bor. Amer. Exsic incd., No. 32. 



On rocks along a rivulet, near Closter, New Jersey. 



Remarkable for its large, subcampanulate and multi-plicate perianth. Al- 

 lied to J. crenulata, Smith, but much larger, &c. 



JUNGERifANNIA PORPHYROLEUCA, NceS, Var. 



Caule dense lateque caespitoso prostrato innovante' ramoso crassiusculo 

 valde radiculoso, radiculis ad cauli insertionem rubris longissimis subfascicu- 

 latis, foliis plerumque rubris pallido viride plus minus variegatis subverticalibus 

 obtusissime subcomplicatis e basi erecta subrecurvis oblongo-quadratis sub- 

 cuneatisve emarginato-bilobis integerrimis, sinu obluso, lobis plerumque 

 acutis subinaequalibus incurvis ; perianthio adscendente subclavato valde 

 exserto a tergo ventreque subappresso apice obtuse 3 — 4-plicato ore con- 

 nivente subciliato ; foliis involucralibus parce majoribus, apice subtruncato 

 obtuse 3 — 4 lobulato et eodemque numero late plicato ; caule gemmifero 

 spiciformi attenuato rigido microphyllo, foliis bifariis arete imbricatis sub- 

 ovatis apice emarginatis eroso-dentatis subintegerrimisve, gemmis rubris. — 

 Hep. Bor. Amer. Exsic. ined., No. 42. 



On old logs in the region of the White Mountains of New Hampshire, Oakes ; 

 also in Canada West, near Belleville, Macoun. 



Remarkable for the usually variegated, often deep red color of the whole 

 plant, and for the cuneate-oblong shape of the leaves. Differs from J. 

 Michauxii, Web., in its usually smaller size, reddish color, prostrate and 

 densely radiculose stems, longer, narrower, subcuneate and vertical leaves, 

 with an obtuse and broad sinus, and shorter, less acute and less incurved 

 lobes, and in the obtusely 3 — 4-lobed, somewhat enlarged involucral leaves ; 

 also in the gemmiferous stems, which are almost precisely as in J. Helleriana. 

 Nees.
