6. Cephalozia grandifolia Stephani, Bibliot. Bot. 21(87): 222. 162. 1916. 



Plants of medium size, whitish-green tinged with reddish-brown in the outer 

 part, in mats or among other bryophytes; stems 1.5-2 cm long, with leaves 0.8-1.0 

 mm wide (if spread), sparingly branched; branches lateral, leafy, of the Frullania 

 type, and ventral-intercalary, flagelliform or short female; stem thick, in transverse 

 section of a cortical layer of large thin-walled cells, the medulla of smaller cells. 

 Rhizoids abundant on the ventral side of the stem. Line of leaf insertion oblique. 

 Leaves distant or rarely imbricate, incurved, broadly ovate in outline, bifid to 

 one-third their length, the sinus narrow U-shaped, the segments triangular from a 

 broad base, the apex blunt-pointed; cells of the segments mostly 30 X 30 /x, the 

 walls thin, without trigones, the cuticle smooth. Underleaves absent. Plants dioicous. 

 Male inflorescence terminal becoming intercalary on the stem, the bracts imbricate, 

 in 3-5 pairs, similar to the leaves, smaller, transverse. Female inflorescence on a 

 short ventral branch, the bracts and bracteoles in 3 or 4 series, oblong, bifid, the 

 margins entire. Perianth cylindrical below, 3-keeled above, the mouth irregularly 

 crenulate and setulose. Young capsule showing the Cephalozia-type arrangement 

 of elaters and spores in horizontal lines from the capsule wall.

7. Cephalozia patagonica Fulford, sp. nov. 



Plantae parvae, albidae, turgidae; caules crassi, ramis ventrali-intercalaribus, 

 saepe patulis geminis, folia oblique inseraa, late ovata, bifida, segmentis, triangu- 

 laribus; cellulae 33-42 X 33-39 parietibus tenuibus. Amphigastria obsoleta. 

 Inflorescentia masculina intercalaris, bracteis similibus foliis. Bractae femineae brac- 

 teolaeque in 3-4 seriebus, bracteis interioribus 1-2 segmentis obtusis in margine 

 dorsali instructis. Perianthii os irregulariter crenulatum. 



Plants of small to medium size, light yellow-green to dull green, in patches or 

 among other bryophytes. Stem thick, turgid, in robust plants 1-2 cm long, with 

 leaves, to 1.5 mm wide, irregularly branched; branches frequent, leafy, ventral- 

 intercalary, often widely spreading in opposite pairs; stem in transverse section 6-8 

 cells across, the cells of the cortical layer in many rows with the ventral rows smaller, 

 the cells of the medulla mostly smaller with thicker walls. Rhizoids abundant from 

 the ventral side of the stem. Line of leaf insertion oblique. Leaves spreading or the
