J. MICHAUXII, Web. 



Perpendicular faces of rocks on mountains. Sand Lake. Catskill 

 mountains. 

 J. minuta, Crantz. 



Rocks, Catskill mountains. 



Amphigastria none; leaves complicate-concave, pectinate-spread- 

 ing-, |-i-bifid, the lobes subequal, ovate, acute or obtuse; inner in- 

 volucral leaves trifid; perianth oval-oblong, subcylindrical, the 

 mouth plicate. Resembles the last, but is more slender, leaves not 

 contorted, areolation more quadrate, C. F. Austin. 

 J. scutata, Web. 



Old logs. Common. 



J. scutata is described as having the perianth terminal, and at 

 length dorsal; in our plant (which may be a distinct species) the 

 perianth is ventral as in Sphagnoscetis communis; the amphigas- 

 tria is smaller, C. F. Austin. 

 J. peckii. (n. s.) 



Decayed wood, Sand Lake. 



" A minute densely caespitose species of a light brownish-red 

 color. Stems rigid — with the leaves — lanceolate in outline, the base 

 densely radiculose and creeping, the apex ascending, microphyllose; 

 rootlets very long and of a light pink color. Leaves imbricated, 

 erecto-vertical, upwardly connivent, concave, rotund-quadrate, 

 somewhat margined; the base obliquely clasping; the ventral mar- 

 gin almost connate with the amphigastria, the dorsal decurrent; the 

 apex somewhat incurved, emarginate-bilobed; sinus acute or obtuse; 

 lobes straightish or somewhat connivent and incurved; areolation 

 large, subrotund; the cellules contiguous and poriform; interstices 

 somewhat obscure; involucral leaves small, unequal and unequally 

 2-3(?)-toothed. Perianth on a very short branch arising from the 

 under side of the stem near the base, minute, ovate, somewhat ob- 

 lique; the mouth oblique, sub truncate, minutely denticulate, at 

 length fissured. Amphigastria minute, oblong-ovate, margined, 

 entire; the apex incurved." Austin MSS. 



Diners from J. scutata as follows: Plant smaller, color light red, 

 stems lanceolate, leaves frequently obtusely bilobed, amphigastria 

 smaller and entire, involucral leaves small and unequal, perianth 

 never terminal and areolation of the leaves larger, C. F. Austin.
