A NEW SPECIES OF HEPATICAE. 
Taken from “The Botanical Gazette,” November, 1903. From an article on “ Odontos- 
chisma Macounii and its North American Allies,” by Alexander W. Evans. 
Odontoschisma Gibbsiae Evans. 
Plants yellowish green, more or less tinged with red or brown, growing 
in depressed mats or creeping among other bryophytes: stems sparingly and 
irregularly branched, 0.3 mm. in diameter, prostrate, ascending at the tips ; 
flagella postical or terminating leafy branches ; vegetable branches varying 
from postical to lateral; rhizoids scanty: leaves imbricated, strongly concave, 
increasing in size from the base of a leafy axis, orbicular, 1 mm. long, not 
bordered, attached by an oblique line of insertion, slightly decurrent antically 
and more or less dillated at postical base, arching to or beyond the middle of 
the axis, margin entire, apex rounded: leaf-cells 16x23 f.i at edge, 19 /a in 
diameter in the middle and 23 /a at the base, with very large and occasionally 
confluent rounded trigones ; cell cavities stellate with distinct pits ; pigmenta- 
tion when present limited to the lining of the cavity, not affecting the limit- 
ing membrane of the pits nor the outer part of the very thick, smooth or 
minutely verruculose cuticle: underleaves minute, except at the base of a 
branch, irregular in shape, sometimes vaguely bidentate: inflorescence 
unknown : gemmae and gemmiparous branches similar to those of O. Macounii 
but the latter with more loosely imbricated leaves.
