50 ERYTHEA. 



Kaniia Trichomanis (L.) S. F. Gray, var. Sprengelii, 

 (Nees.). Mill Valley and Olema. Also the propaguliferous 

 form. 



Cephalozia hicuspidata (L.) Dumort. Olema, Sisson, and 

 other places. 



Cephalozia pleniceps ( Aust.) Underw. On bank of stream, 

 Sisson. Determination based on Austin's description and on 

 Spruce's detailed diagnosis of C. crassiflora, which Pear- 

 son 3 considers the same. 



Cephalozia divaricata (Sm.) Dumort. On charred red- 

 wood stumps and on ground, Mill Valley, and on rocks near 

 Lake Lagunitas, Marin Co. 



Cephalozia Turneri (Hook.) Spruce. On roadside banks 

 in various parts of Mill Valley, Marin Co., and also near 

 Lake San Andreas in San Mateo Co. Not before reported for 

 America. The occurrence of this very rare Old- World hep- 

 atic in California is a matter of much interest. It has been 

 found in a few localities in Ireland, England, and France, in 

 the Canary Isles, and there is one known station for it in 

 northern Africa. Through the kindness of Mattliew B. 

 Slater, Esq., of Malton, England, I was enabled to make 

 comparisons with an English (sterile) specimen. The in- 

 most involucral leaves are highly connate as in a form to 

 which Spruce refers (On Cephalozia, p. 72) as having been 

 collected in Ireland by Lindberg. 



Blepharostoma irichophylhim (L.) Dumort. With an 

 undetermined Jungermannia. Fish Creek, Mariposa Co., 

 Miss Byxbee. 



Lepidozia reptans (L.) Dumort. On old logs, Sisson, and 

 in Redwood Canon near Mill Valley. 



Radida complanata (L. ) Dumort. Rarely found on trunks 

 of trees in Strawberry Canon, Berkeley (leaf margins gem- 

 miferous) ; more abundant in Bear Valley near Olema. 



Musci. 

 Acaulon muticum (Schreb.) C. Muell. On roadside near 

 the " Old Mill," Mill Valley.
