100 JUNGERMANNIACEAE 
anth has been drawn in part from Gottsche’s figures. Sterile 
plants bear some resemblance to Vardia obovata but differ in the 
almost entire absence of root-hairs, the softer, more decurrent, 
and much more longitudinally affixed leaves. 
А type duplicate of Jungermannia Bolanderi from the hand of 
Dr. Gottsche, together with his original pencil sketches of the 
species, is preserved in the herbarium of Harvard University, 
Which is true also of Dr. Gottsche's Jungermannia Danicola, J. 
Mülleri Danaensis, and J. rubra. We have made an. effort to see 
the remainder of Dr. Gottsche’s material of this and of his other 
Californian species, but without success. Dr. Gottsche’s herbarium 
is in the possession of the Royal Botanical Museum at Berlin, but 
Dr. Hennings, in response to our inquiries, writes that the Gottsche 
collection is only partly arranged and that the Californian speci- 
mens desired cannot thus far be found.

Dark green, sometimes brownish or blackening, forming thin, 
loosely or closely interwoven mats : stems creeping, commonly 
ascending at apex, simple or sparingly branched, rhizomatous from 
the ventral surface or now and then innovating from the axils of 
the bracts ; root-hairs usually long and numerous, colorless or 
yellowish-brown : the lower leaves loosely disposed, scarcely con- 
the upper closer, more transversely attached and more erect, à 
elliptical-oblong, .3 9 X .27—8 mm., obtuse, somewhat concave 
or nearly plane, entire or slightly repand, not decurrent ; leaf-cells 
transparent, thin-walled, scarcely or not at all thickened at the 
angles, the median 18-35 и, only a little enlarged toward the base, 
the marginal slightly smailer and subquadrate ; cuticle finely striatu-
