that the underleaves are often coalescent on one side with a leaf; 
in H. Flotowianus they are constantly free. The two species differ 
finally in habitat. H. scutatus prefers logs or dry rocks, rarely as- 
cending to a high altitude, while H. Flotowianus grows on damp 
rocks or in subalpine bogs. 
Schiffner! recognizes two modifications of the species, which he 
designates as forma typica and var. uliginosus, respectively. He 
admits, however, that they intergrade. In the forma typica, to which . 
the Mt. Madison specimens might be referred, the stems are more or 
less prostrate, and the lobes of the leaves are often sharp. In the 
var. uliginosus, the stems are more or less erect, and the lobes of the 
leaves are mostly rounded. Forma typica grows in somewhat drier 
localities and occasionally produces reproductive organs; var. uligi- 
nosus grows in deep swamps and is always sterile. Full descriptions 
of the species, with figures, may be found in European manuals. 
4. CALYPOGEIA FissaA (L.) Raddi. On banks, Mt. Washington 
Carriage Road, New Hampshire, near the three mile post, August 7, 
1917 (A. W. E.); on shaded earth, Triple Falls, Randolph, New 
Hampshire, August 23, 1917 (A. W. E.); Vineyard Haven, Martha’s 
Vineyard, Massachusetts, August, 1917 (H. E. Greenwood). New to 
New England. In 1907? the writer published an account of C. fissa, 
giving a full synonymy of the species. At that time he was able to 
cite only two stations, namely: Lafayette, Louisiana (Langlois), and 
Devonshire Marsh, Bermuda (E. G. Britton). Nichols? has since listed 
the species from Barrasois, Cape Breton, Nova Scotia, and the three 
following stations may now likewise be placed on record: Magnolia 
Swamp, Mt. Pleasant, District of Columbia (M. B. Waite); Gaines- 
ville, Florida (N. L. T. Nelson); and Boston Mountains, Swain, 
Arkansas (W. H. Emig). It is clear from these citations that the 
species is widely distributed in North America. Its range in Europe 
is equally extensive, and it has also been reported from Japan. 
The species is characterized by shortly bidentate leaves and by 
wide and deeply bifid underleaves, the lobes of which are blunt or 
sharp and usually bluntly unidentate on the sides. When these 
features are at all constant, as in the material from Bermuda, the 
plant is easily distinguished from the closely related C. Trichomanis 
(L.) Corda. Unfortunately this is not always the case. In some
