In size and general appearance A. sicaefolia resembles Cololejeunea diaphana T 
but the very different lobules of the two species will at once distinguish them. 
In A. sicaefolia , moreover, the surface of the lobes is more or less roughened 
from projecting cells, while in C. diaphana the surface is smooth, the cells being 
plane or nearly so. 
8. Frullania Bolanderi Aust. 
Collected at Bic, Rimouski County, Quebec, by J. F. Collins, in July, 1907 
(No. 5101). The present species is widely distributed along the Pacific Coast 
from British Columbia to California and was supposed to be confined to that 
region until very recently. A few months ago Conklin 1 2 reported it from Lake 
Nebagamon, Douglas County, Wisconsin, and the station recorded above ex- 
tends its known range practically across the continent. Two Asiatic stations 
from the island of Sakhalin, based on collections made by the Abbe Faurie in 
1908, may likewise be quoted: namely, Mereya, near Korsakovski (No. 124), 
and Kimonai (No. 102). Specimens from these two stations were distributed in 
Faurie’s “Hepatiques du Japon.” 
A full description of F. Bolanderi , with figures, was published by the writer 
in 1 897.2 The species can usually be at once distinguished, even where sterile,, 
by the. upright flagelliform branches, which are present in greater or less abund- 
ance. These branches are limited in growth and give rise to organs of vegeta- 
tive reproduction in the form of caducous leaves (Brutblatter). After these have 
fallen away the branches are leafless except for the persistent underleaves and 
the leaves of the terminal bud. Similar flagelliform branches have been described 
by the writer in certain tropical Lejeuneae. 3 
9. Frullania mexicana Lindenb.; G. L. & N. Syn. Hep. 425. 1845. 
Collected in May, 1912, on trees, north side of Mt. Lemmon, Catalina 
Mountains, Arizona, by D. S. Johnson. Although this is the first record for the 
United States, the writer would now lefer to F. mexicana a specimen collected 
in New Mexico by E. O. Wooton in August, 1899, and already recorded under 
the name F. inflata Gottsche. 4 This specimen grew on oak, at Cloudcroft, 
Sacramento Mountains, at an altitude of 8500 feet. The original material of 
F. mexicana was collected somewhere in Mexico, no definite locality being 
given in the Synopsis Hepaticarum, and no other stations for the species are 
known at the present time. 
Stephani, in his Species Hepaticarum ( 4 : 329. 1910), refers F. mexicana 
to the subgenus Chonanthelia. Apparently, however, he is not altogether clear 
about the species because a few pages later in the same work he includes it among 
the synonyms of F. tetraptera Mont. As a matter of fact the plant is not a 
Chonanthelia at all but belongs to the subgenus Trachycolea. This fact is clearly 
brought out by original description of Lindenberg, who compares F. mexicana 
with F. eboracensis Gottsche, and by the type specimen preserved in the Linden- 
berg herbarium at Vienna. Through the kindness of Dr. Zahlbruckner this
