[305] HEPATIC^ OF ALASKA 359 



lobed leaves, and in its thinner walled leaf-cells with smooth or nearly 

 smooth cuticle and smaller trigones. In L. kunzeana (Hiiben.), which 

 is also a close ally, the leaves are more distinctly complicate, so that 

 the plant appears flattened rather than terete-foliate as in Z. quadri- 

 loba; the leaves moreover are usually only bilobed, they lack basal 

 cilia, and their cells have a smooth or minutely striate-verruculose 

 cuticle. 



28. Lophozia minuta (Crantz) Schiffn. 



Columbia Fiord (C. & K. 1388, in part) ; Orca (T. 151 1, in part) ; 

 Hall Island (T. 1518, in part); St. Lawrence Island (T. 2125, in 

 great part). The species was first collected in Alaska by the Drs. 

 Krause at Chilcoot ; it has also been found at Sitka (U. S. Fish Com- 

 mission, 1894), and on Fopof Island (Townsend). 



29. Lophozia ovata (Dicks.) M. A. Howe. 



Yakutat (T. in very small amount, mixed with 1527). New to 

 Alaska. 



The generic position of this little species is still a matter for discus- 

 sion : by certain authors it is placed in the genus Diplophylleia Trevis. 

 {Diplophyllum Dumort.) ; by others it is considered a species of the 

 Sphenolobus section of Lophozia} It forms, in fact, a connecting 

 link between these two groups of Hepaticae. The closely related 

 Diphphyllum argenteum Spruce,* a species apparently confined to 

 the northwestern coast regions of our continent, is also recorded as 

 Alaskan by Professor Underwood.' 



Lophozia saxicola (Schrad.) Schiffn., which was collected by the 

 Krause brothers in Alaska, does not appear in the Harriman collec- 

 tions. 



30. Plagiochila asplenioides (L.) Dumort. 



Farragut Bay (T. 1469, a single sterile stem). The species is 

 known also from Sitka (U. S. Fish Commission, 1894) and from near 

 Yakutat (Funston), and ought to be widely distributed in Alaska. 



31. Mylia taylori (Hook.) S. F. Gray. 



Hot Spring (T. 1470); Juneau (Setchell 1229, in part); Doug- 

 las Island (T. mixed with 1495, 1496, and 1498) ; Virgin Bay (T. 

 1474, in part) ; Farragut Bay (T. 1485, in part) ; Orca (T. 1490,
