106 JUNGERMANNIACEAE 
these marginal or more commonly in clusters at the apices of the 
lobes, irregular, somewhat tetrahedral or subcubical, mostly uni- 
septate ; median leaf-cells rounded-hexagonal, 24-32 и, trigones 
distinct but variable in size, the cuticle smooth or slightly rough- 
ened: subulate or broader and bifid underleaves usually present in 
association with Ше 9 bracts and sometimes on young “‘subfloral” 
innovations, otherwise wholly wanting: dioicous: androecia term- 
inal, oval; 4 bracts imbricate, transversely inserted, obtusely sub- 
complicate, ventricose ; antheridia in pairs or single, oval, 12-18 
mm. in greatest diameter, on short stalks composed of a single 
row of cells, accompanied by a few short paraphyses: 9 bracts 
somewhat larger than the leaves, the inmost déeply and unequally 
2-5- (mostly 3- or 4-) lobed, often slightly plicate, the lobes 
acute or subobtuse: perianth cylindrical-obovoid, 2-3 mm. long, 
1-1.5 mm. in greatest width, unistratose except at extreme base, 
the plicate mouth ciliolate-denticulate: calyptra mostly bistratose: 
seta 10-15 mm. long ; capsule-valves purplish- or yellowish-brown, 
.9-1.1 mm. long, of three layers of cells, the inner with close an- 
nular or semiannular fibers, the outer with nodular or imperfect 
semiannular thickenings; spores yellowish- ог reddish-brown, 
finely granulate-papillate, 12-14 и; elaters fusiform, subobtuse, 
80-130 и x 8-10 p. 
On soil in moist places and on decaying wood. Mt. Dana àt 
about 3100 m. alt., associated with Lophoszia heterocolpa, Jungtr- 
mannia Danicola, and 7. Bolanderi (Dr. НОЋ. Bolander, Septem 
ber, 1866); between Farewell Gap and Mineral King, Tulare Со, 
alt. 3500 m. (Coville and Funston, Death Valley Expedition, 0 
1573, Aug. 10, 1891); beside “ Horse Camp Spring,” above timber- 
line, Mt. Shasta, alt. (est.) about 3100 m. (Howe, August, 1894) 
These three high-altitude specimens, the second 8 and the 
others sterile, seem clearly to fall in the form-cycle of Lophozit 
ventricosa, agreeing essentially with the soft-leaved terricolous cor 
ditions of this species from other parts of the world, as represente? 
for example, in Carr. and Pears. Brit. Hep. по. 171. T be р 
grow in densely compacted tufts, and the walls of the leaf-cells, № 
the last two specimens especially, are but slightly thickened at the 
angles save in the more exposed parts. Lindberg and Ае 
(Kongl. Sv. Vet. Akad. Handl. 23°: 50. 1880) would restrict 66 
application of the specific name ventricosa to forms with poor 
developed trigones, but. Lindenberg (Syn. Hep. Eur. 86. е |
