NARDIA 95 
.16-.2 mm. in diameter, short-stalked, accompanied by a few short 
paraphyses: Ф bracts gradually larger than the leaves, more ге- 
pand and commonly more conspicuously marginate, crowded and 
suberect or rather loosely disposed and spreading, the uppermost 
one or two more or less adnate to the base of the perianth or to 
the perigynial tube formed by the hollowed-out stem-apex, the 
very rarely occurring bracteole small, obovate, semiorbicular, or 
linguiform : perianth usually tinged with red or purple, nearly im- 
mersed or exserted 14-2 its length, subcomplanate-ovoid to nar- 
rowly obovoid or prismatic, 1.5-2 mm. long, .8-1.3 mm, in greatest 
width, nearly always, especially when young, distinctly quad- 
rangular (rarely pentagonal), the angles often incrassate (of two 
layers of cells), the perianth wall otherwise unistratose except in 
the basal third or fourth, the mouth at first abruptly contracted 
into a very short subtubulose mucro, rather obscurely ciliolate- 
denticulate, at length lacerate: calyptra often reddish or purple, 
unistratose toward the apex, otherwise bistratose: capsule dark 
brown, ovoid, .7~.8 mm. in greatest diameter, the wall consisting 
of two layers of cells; seta 4-10 mm. long; spores brown, 13- 
16, very minutely granulate; elaters brown, bispiral, attenuate 
at кен extremities, contorted, 80—120 и long, 8-13и in maximum 
width.

On moist, usually exposed banks in the Coast Range Moun- 
tains, especially near the sea.. Mendocino (Dr. H. N. Bolander) ; 
Santa Cruz (W. G. Farlow, May, 1885), Santa Cruz Mountains 
(L. M. Underwood, August, 1888); near Lake San Andreas, San 
Mateo Co.; Bolinas, Marin Co. (W. А. Setchell); near Cazadero, 
Sonoma Co.; Mendocino (582, 591, 620, 682); Eureka (902, 924). 
The Californian forms mostly agree with Gottsche's Junger- 
mannia rubya, founded on a specimen collected on “ metamorphic 
Sandstone, quite near the coast" at Mendocino by Dr. Bolander, 
but Jungermannia rubra seems to us not to differ in any essential 
Structural characters from the European conditions of Мала cren- 
Майа which have at times been known as Jungermannia gracillima 
and /, Genthiana. Leaves conspicuously margined by cells 2 or 3 
times the size of the adjacent occur in the Californian specimens, 
though rarely. In general, the leaves here are only submarginate. 
But both Californian and European specimens show such extremes 
9f variation in this particular in different parts of a single tuft or 
“ven in different parts of a single plant that this character cannot
