74. IRIDACE^. 441 



Iris Xiphium has been reported to grow in Worcester- 

 shire. (Nash, quoted in B. G.). Iris pumila is fomid "ap- 

 parently indigenous in Chartley meadows," Leicestershire. 

 (Miss Kirby, in Phytologist, iii. 179). And Iris germa- 

 NiCA grows in Staffordshire, " about a ditch in Stoke mea- 

 dows, introduced." (Garner s Natural History of Stafford- 

 shire.) It seems not worth while to mention each of these 

 species under a distinct head.

Hibernian. This was quite an unexpected discovery in 

 Ireland ; although not the first American species which had 

 been found there, and not elsewhere in Europe, unless by 

 introduction. Whether truly an aboriginal native, or sim- 

 ply naturalized in Ireland, has not been yet quite clearly 

 shown or stated by its discoverer, Mr. Lynam. The loca- 

 lity has been variously described, and is " near Woodford, 

 Loughrea, county of Galway." (Phytologist, ii. 765).
