9. Cephalozia bischlerae Fulford, sp. nov. 



Caules albo-virides, ramis typo Frullaniae vel ventrali-intercalaribus, foliis sub- 

 transverse insertis; folia longe rectangularia, patentia, bifida, segmentis longe lance- 

 olatis, apicibus 3-4 cellularum. Amphigastria obsoleta. Monoica. Inflorescentia 

 masculina terminalis, bracteis parvis foliiformibus. Inflorescentia femina in ramo 

 brevi ventrali, bracteis bracteolisque in 3-4 seriebus, longioribus quam foliis, bifidis. 

 Perianthium longum, ore brevi-ciliato. 



Plants whitish-green, prostrate with the tips ascending, in mats or among other 

 bryophytes; stems 1-3 cm long, irregularly branched, the branches lateral, of the 

 Frullania type or ventral-intercalary and leafy or short and bearing a female in- 

 florescence. Stem in transverse section of a cortical layer of large cells on the dorsal 

 side and small cells on the ventral side, surrounding a medulla of rather small cells. 

 Rhizoids from the ventral side of the stem. Line of leaf insertion oblique, subtrans- 

 verse. Leaves distant, long-rectangular, mostly erect-spreading, to 0.5 mm long, 0.2- 

 0.3 mm broad below, bifid to one-half or more, the segments long lanceolate from a 

 2- to 4- celled base, ending in a uniseriate 3- or 4-celled tip, the cells 3-5 times as 

 long as broad; cells of the base of the segments 52-65 X 26 ju., the walls uniformly 

 thickened, without trigones, the cuticle smooth. Underleaves none. Plants monoicous. 

 Male inflorescence terminal on the stem or a long branch, the bracts in 5 or more 

 series, leaf-like, erect, the lamina pouched, the segments spreading. Female in- 

 florescence on a short branch, the bracts and bracteoles in 3 or 4 series, similar to 

 the leaves, longer, the segments widely spreading to falcate. Perianth to 2 mm or 

 more long, narrow, cylindrical below, 3-keeled above, the mouth contracted, short- 

 ciliate.

Plants of small to medium size, flaccid, whitish tinged with brown or becoming 

 light brown, ascendant in tufts or among other bryophytes; stems 1-3 cm long, 

 with leaves 0.6-1.0 mm wide, occasionally branched, the branches lateral, of the 

 Frullania type, leafy, more rarely ventral-intercalary and leafy or occasionally small- 

 leaved; stems with the cortical cells twice as long as wide, in transverse section the 

 cortical layer with the dorsal rows of large cells, the ventral rows small, and the 

 medulla of large and small cells. Rhizoids colorless or brownish, from the ventral 

 side of the stem. Line of leaf insertion subtransverse. Leaves ovate, 0.6-0.9 mm 

 long, 0.4 mm wide at the middle, bifid to one-half their length, the segments triangu- 

 lar from a base 8-10 cells across, tapering to a slender apex with a tip of usually 2 

 cells; cells longer than broad, those of the lower part of a segment mostly 52 x 26 /*, 

 some larger, some smaller, the walls uniformly thickened, the cuticle smooth. Under- 

 leaves absent. Plants dioicous. Male inflorescence terminal becoming intercalary 

 on the stem or branch, the bracts in 3-6 pairs, similar to the leaves, somewhat 

 smaller, pouched below. Female inflorescence terminal on the stem, the bracts and 

 bracteoles in 3 or 4 series, bifid to one-half, similar to the leaves, larger. Perianth
