 not of Libert.) {Lcjcunca cchiitata of Aust., not of Taylor.) {Lejeiinea 

 Biddlccomiac Aust.) 



Pale or bright green, scattered or dejDressed caespitose: irregularly pin- 

 nately branched: leaves distant to imbricated, lobe obliquely to widely 

 spreading, ovate, apex varying from rounded to acute, usuall}^ obtuse, mar- 

 gin crenulate or denticulate from projecting cells; lobule inflated, ovoid to 

 globose, keel bearing an obtuse, sometimes indistinct tooth beyond the 

 middle, and another tooth composed of two cells midway between this tooth 

 and end of keel : stylus conspicuous, composed of two to ten cells in a single 

 row, sometimes two cells broad a part of its length; inflorescence dioicous or 

 autoicous : female on a leading branch, bracts unequally bifid, the lobe ob- 

 liquely spreading, broadly ovate; perianth partly exserted, obovoid to 

 oblong, not compressed, rounded to truncate at the apex, with a short beak 

 sharply five-keeled in upper part, surface roughened from projecting cells' 

 except near base: male spikes on leading branches ; bracts similar to leaves, 

 but with proportionately larger lobule; antheridia singly or in pairs. On 

 trees and rocks. Range from Ontario and Massachusetts to Alabama and 

 Florida. Distributed in Sull. Musci Allegh. 275 (as Lejeitnca calcarea). 

 Aust. Hep. Bor. Am. 99 (as Lcjcitnea cchi?tata). Hep. Amer. 51 (as L. cal- 

 ca7^ca). Can. Hep. 13 (as L. calcarea). Found best developed on trees 

 especially in swamps. A tiny species, when dry hardly noticeable to the 

 unaided eye; leaves >^ mm. long. 



CoLOLEjEUNEA JooRiANA (Aust.) Evaus. {Lejeu7iea Jooriana Aust.) Fig. 6. 



Yellowish green or whitish, darker with age, scattered or loosely caespi- 

 tose: irregularly pinnately branched: leaves imbricated, lobe widely spread- 

 ing, ovate, gradually narrowed from just below middle to the rounded, 

 obtuse or subacute apex, margin entire or subcrenulate ; lobule inflated, 

 ovoid, free margin with two teeth as in last species; stylus inconspicuous and 

 soon obsolete, composed of two cells in a row or even of a one-celled papilla ; 

 cells scarcely convex ; hyaline cells at apex one to ten in number, elongated, 

 usually in a single row, their ends usually free, hyaline cells sometimes also 

 along the antical margin, usually becoming indistinct with age; inflorescence 

 synoicious or sometimes paroicous; female usually on a leading branch, 

 rarely on short branch; bracts similar to leaves, with more or less inflated 

 lobule, stylus three to four cells long sometimes ; perianth half exserted, 

 broadly ovoid to obvoid, rounded at base, rounded, truncate or slightly refuse 

 at apex, with extremely short and indistinct base, somewhat flattened, 

 antical face plane or with broad, low keel, lateral keels sharp to blunt, postical 

 keel broad and two angled: antheridia borne singly or in pairs in the axils of 

 the female bracts: spores elongted, angular, greenish. On bark and reed. 

 North Carolina, Florida, Louisiana, Differs from C. Biddlecomiae in its ordi- 

 nary leaf cells which are plane or nearly so, also in its inflorescence, hyaline 

 cells, and much shorter stylus. Sayre, Pa.
