78 LEJEUNEA HOLTII, A NEW HEPATIC FROM KILLARNEY. 
Europe, but the whole breadth of North America. All the plants 
T have seen are males, but Lindberg assures us he has found the 
two sexes intermixed in specimens from Vancouver Island, yet still 
no fruit. The fine A. Woodsii, although very rare and 
local, has a wide ran, in Ir eland, a and Mangerton Mts.; 
our rarer hepatics are in similar case, e. g., Jungermannia Orcadensis 
and Carringtoni, Plagiochila tridenticulata, Kantia arguta, Adelanthus 
are available, and are in — for the dispersal of propagula of 
every kind as for that of spore 
We have seen that our Seealiac Lejeunee cannot have reached us 
from the east, neither can they have come from the cooler parts of 
the North Ameri rican continent, whose hepatics are almost identical 
with those of Continental Europe. a n’s enumeration of = 
hepatics of Pg ice Columbia, &e.,* does not include a single specie 
not foun urope. Even Sullivant’s ‘ oileiine of the United States 
east of the 1 Mississipi’ does not contain above two or three hepatics, 
growing north of the parallel of 40°, which we have not also in 
ain. When we reach the Southern States, we meet with a few 
additional species of Lejewnea and Frullania, two of which, L. 
clypeata Schwein. and L. lucens Tayl., approach respectively our L. 
Mackaii and L. deosea but are abundantly distinct. The nearest 
congeners, however, of our Britannic species of Lejeunea, and of 
r ut i 
sa 0 onecuaea not od the ee species Britain 
but their near allies or oe ere Several species resembling 
i Mackaii in the entir tipules and — perianths grow 
usually spinulose leaves, ny bierural inn peor the armed keels 
of the perianth. L. Holtii, as already shown, resembles, not only 
in character but in its iahitae three or four tone found at the 
cataracts of two great equa uatorial rivers. L. flava (Sw.),t the 
—— neces of Killarney, &c., is the commonest of all Lejeune, 
nly in tropical America, but in all other hot countries 
(Madeirs, West fe East Africa, India, Philippine Islands, &e.).
