AN ENUMERATION OF THE WASHINGTON AND OREGON 
HEPATICAE COLLECTED BY MR. A. S. FOSTER, 
1904 - 1909 . 
Caroline Coventry Haynes. 
This collection is in the Herbarium of the Sullivant Moss Society. It has 
given me much pleasure to determine these specimens collected by Mr 
Fos‘ter at various times during the past six years. When I add that the 
great majority of them were found in full maturity, an idea of the value of 
the collection becomes evident. Thanks are due to Dr. Evans and Miss 
Lois Clark for verifying, and in several instances, correcting, my determina- 
tions. 
Nardia obovata (Lyell) Carringt. , and Mvlia anomcila (Hook.) S. F. 
Gray were, when collected, new to Washington. 
The fallowing species are generally found in colonies: Radula com- 
planata , R . Bolanderi , Scapania Bolanderi and Porellanavicularis, grow- 
ing indifferently on live or decayed wood and rocks. Riccardia latifrons , 
Scapania umbrosa , Lophozia incisa , Cepholozia lunulaefolia , C. bicuspi- 
data , Lepidozia reptans and Calypogeia Trichomanis , growing on old damp 
logs, shaded.
