1898-1902. No. 2.] VASCULAR PLANTS OF ELLESMERELAND. 171 



As this plant, especially through C. concinna, Th. Fr., stands in 

 near affinity to the species of the genus Catabrosa, there is hardly 

 any cause for taking up the genus Phippsia again. C. algida, as 

 Andersson & Hesselman, 1. c, also observe, is one of the first grasses 

 to flower — I found it flowering in June — but it may be found still 

 flowering at the end of the summer, as different individuals attain to 

 flowering at very different times. Ripe fruit was seen already in July. 

 It is rather variable as to size, ramosity of the panicle, etc., and was found 

 both in wet places among moss, around pools, and in inundated clay 

 fields, and also in rookeries and other manured places where it becomes 

 especially large and thriving. Hart, 1. c, p. 40, also speaks of it as 

 "growing in mud by the sea edge on ground which is flooded by spring- 

 tides", but I have never seen it so near the shore line.

The confusion concerning the correct name of this plant, is due 

 principally to an error in Linnaeus, Sp. plant., Ed. 1. Here, under the 

 genus Aira, as n. 1 is described (p. 63) a species, A. spicata, the
