others in the use of it. Spruce in 1882 named and described C. catemtlata, 
mentioning denticulate perichsetial bracts, which however, in rare cases 
were nearly or quite entire. Recent European writers believe that Spruce 
in reality described two distinct specific types ; those with entire bracts being 
the true Jungermannia catemtlata of Hiibener which is unknown in North 
America, those with denticulate bracts being Jungermannia reclusa of 
Taylor. Now Taylor, in his original description in 1846, does not mention 
the bracts, and the plants thus labeled in his herbarium include several dis- 
tinct species’in poor condition : he probably did not thoroughly understand 
the species, therefore, the use of Lindberg’s name, C. serriflora , is to be 
commended. I quote again from “ Notes, etc.” : “ From other species grow- 
ing on rotten logs it may be distinguished by its widely spreading and deeply 
bifid leaves, the acute divisions being straight or slightly connivant; by its 
leaf cells with uniformly thickened walls ; by its dentate or denticulate 
perichsetial bracts, and by its thin-walled, three-angled perianth with ciliate 
mouth.” Range from Canada to the Gulf States. 
In the damp depressions of the fungus I found Riccardia latifrons 
Lindb. closely crowded together; with narrow thallus, palmately divided. 
Jamesoniella autumnalis (DC.) Steph. the Jungermannia Schraderi Martius 
of Grey’s Manual sprawled here and there, sterile specimens look a little like 
Odontoschisma prostratum, as Dr. Evans once pointed out to me in a letter, 
only “its leaves are less distinctly margined and show larger cells.” Jame- 
soniella autumnalis , Kantia trichomanis (L.) S. F. Gray, and Lojhozia ven- 
tricosa (Dicks.) Dumort. were the largest members of the colony, individual 
specimens being easily recognizable with a hand lens. There are excruci- 
ating nomenclatorial changes being endured by the Kantias in Europe but 
the contagion has not yet spread over here. They can be found in May in 
the Adirondacks bearing capsules which open in four curiously-twisted 
flame-colored lobes at the end of a very long and slender seta. 
Dr. Howe gives a good key to the Lophozias in his “ Hepaticse and 
Anthocerotes of California,” Memoirs of the Torrey Botanical Club, Vol. 7. 
p. 104, 1899. I will insert the description of L. ventricosa: “ Leaves two 
(rarely three) lobed 1/5 to 2/5 their length, close or approximate, the lobes 
acute, occasionally apiculate, rarely subobtuse, entire, the sinus broad; 
median leaf cells 24-327*.” His account of the species is most interesting. 
Lophozia incisa (Schrad.) Dumort. is one of my favorites, the finely- 
drawn fluted spinulose-dentate leaves clasping the stem remind me of stiff 
lace ruffs in the reign of Queen Bess. And of the filamentous Blephar- 
ostoma trichopyyllum (L.) Dumort., how shall I speak! The hand-lens 
shows the spider-web-like leaves and stems flung gauzily here and there 
over the larger species, but it requires the high power of a microscope to 
discover its structure. Besides these ten hepatics, there were two mosses, 
immature plants of Hypnum reptile and Dicranum sp?
