lateque carinato, utrinque uni — plurinervoso, carina biangulata, nervis angu- 

 lisque plus minus alatis undulaiisque. — Hep.Bor. Amer. Exsic.ined., No. 104. 



Closely adhering to the surface of steep shaded rocks, near Closter, New 

 Jersey ; very rare. Also, Texas, Wright in Herb. Sulliv. 



Remarkable for the short, innovately much branched stems, and orbicular, 

 plane, subascending, scarcely if at all oblique leaves, with the auricle almost 

 always expanded into a small, oblong, concave, obtuse lamina. Areolation of 

 the leaves distinct, scarcely enlarged in the centre at the base. Perianth lon- 

 ger than in F. Viryinica and more exserted, but angled much in the same man- 

 ner ; however, the angles are never crested, and the " style " or mouth is very 

 diiferent ; (tubular and considerably elongated in F. Virginica). The stems 

 are much shorter, the leaves larger, and the perianth very different from /. 

 Eboraeeiisis. 



Frullania Sullivantii, Aust. 



F. digyna; caule arete adpresso vage breviter ramoso ; foliis subrotundig 

 convexis integerrimis obtusis, auricula magna galeata rotunda hititudinem folii 

 I aequante cauli adproximata ; amphigastriis obovatis obtuse bifidis subinte- 

 gerrimis caule parce latiorihus illis versus perianthiura oblongis cuneatisve, 

 lobis obtusissimis vel supr«mis acutis ; perianthio obovato subcompresso brevi 

 rostrato, dorso minute 1 ( — 2)-nervos0, ventre unicarinato, carina biangulata 

 bialatave ; involucri foliis rotundis cum perianthio et uno alterove cum amphi- 

 gastriis connatis, lobulis paralellis subrequalibus, (ventrali \ — J angustiori). 



On the bark of trees, Georgia, SuUivaut ; also South Carolina, Curtis (in 

 Herb. Sulliv). 



Differs from F. inflata, Nees, in the fewer and less distinct nerves on the 

 back of the much more compressed perianth, in the shorter amphigastria, in 

 the auricle placed close to the stem, «&c. ; and from F. Oakesiana in the differ- 

 ent perianth, smaller auricle, more unequal lobes of the involucral leaves, &c. 



Frullania Oakesiana, Aust. 



F. monogyna; caule vage ramoso intricato, ramulis fertilibus brevibus sub- 

 erectis ; foliis suboblicjue orbiculatis laxe imbricalis subconvexis raargine leni- 

 ter repandis, auriculis maximis (folia fere sequantibus) rotundatis cucullato- 

 galeatis cauli fere contiguis, lobulo dentiformi interjecto nullo vel fere 

 obsolete ; amphigastriis ovato-rotundis vel subobovatis caule parce latioribus 

 bifidis integerrimis subserratisve ; perianthio parvo subobovato subinflato 

 ventre late carinato, utrinque varie numero (1—7) nervoso vel alato, cietero- 

 quin Isevi ; involucri foliis bilobis integerrimis cum amphigastriis uno alterove 

 subalte conuatis, lobis ffiqualibus obtusis paralellis. 



On the bark of Bctula excelsa, in the region of the White Mountains of New 

 Hampshire, Oakes. 



A small species, scarcely as large as F. Eboracensis^ and of a reddish color. 

 Remarkable for the very large auricle (more than | the diameter of the leaf,) 

 for the more or less connate involucral leaves, and for the extremely variable 

 number of rib-like nerves of the small, subintlated perianth. 



Frullania Bolanderi, Austin MSS., (1865.) 

 F. trigyna ? caule repente inordinate fasciculatim ramoso fiagelifero, ramia 

 fructif'eris adscendenti-erectis clavatis ; foliis parvis imbricatis oblique orbicu- 

 latis convexis marginatis, basi inauriculam magnam orbiculatamgaleatam com- 

 pressam (subtus concavam) margine crassiusculam basi integram compUcatis; 

 amphigastriis subpatentibus minimis orbiculatis subobovatisve bifidis, lobis 

 obtusis vel acutiusculis integerrimis vel plerumque repando-dentatis serratisve; 

 foliis involucralibus duplo vel triplo majoribus appressiusculis cum amphigas- 

 triis alte connatis ; perianthio potius magno comprcsso ina^qualiter triangulari 

 obovato-elliptico, dorso concavo vel demum convexiusculo leniter bicostato 

 versus apicem breviter et in;equaliter 2 — 4 nervoso, ventre obtuse unicarinato 

 versus apicem leniter bicostato, cffiteroquiu la?vi.
