 of Prof. S. F. Baird the f re turn Senjawin is on the Asiatic side, and lies in latitude G4° 45' north 

 and longitude 172° 35' west, between Kayne Island and the Asiatic shore.)

T. cernuium, Trin., Sitka. 



Aira ccespitosa, Trin., Unalashka and mainland. 



A. ccespitosa, Trin., var. bottnica. Sitka. (Dr. Rothrock adds that, in looking - over the speci- 

 mens of A. ccespitosa in Herb. Gray, he finds one from the Sandwich Islands, and another from 

 Fort Vancouver, both of which appear identical with our forms from Sitka. They having been 

 authentically named by Colonel Munro as Aira ccespitosa var. bottnica, he has labeled the Sitkau 

 specimens in accordance with his determination. Trinius, in Icones Granimum, in the text front- 

 ing his A. fiexuosa, var. bottnica, speaks of an Aira very similar to A. bottnica being fouud at Sitka 

 by Mertens. Bongard is silent on the subject in " Vegetation of Sitka," though he finds in Herb., 

 Gray, a specimen similar to the Sitkau ones marked (but from Unalashka) as A. ccespitosa, var. 

 longifiora. Trinius 1. c, Vol. Ill, writes of the same plant from Sitka, "Cpeterum hac varietate 

 transitus quidam sistitur ab A. ccespitosa ad flexuosam"; which statement seems probable enough.)
