40 FLORA ORCADENSIS. 
Genus CXIL—ARCTIUM (Linn.), Burdock. 
224, A. INTERMEDIUM (Lange). 
This plant is found on links and waste places 
—Newark, Deerness; Hoy, Westray, &c. In Dr 
Duguid and R. Heddle’s list nemoroswm is given ; 
but, as some doubt regarding its accuracy had been 
expressed, I sent my specimen from Newark to Mr 
Ar. Bennett, who said it was as above, with this 
reservation—that the specimen was not a whole plant. 
In “Ann. Scot. Nat. Hist.,” July 4895, Col siaeaen 
Johnston, C.B., states that specimens from Hoy were 
identified by the late Dr T. J. B. Boswell on the 
authority of Prof. C. C. Babington. Specimens from 
Skaill were identified by Prof. Babington as probably 
A. nemorosum (Le}.) 
Genus CXIIIL.—SAUSSUREA. 
925. S. ALPINA (DC.), Alpine saussurea. Rather 
scarce. 
Hoy Hills (Dr Boswell). I received a few fine 
specimens from Rousay (Kierfiold Hill) through Mr 
McKay, Schoolhouse, Finstown. 
Grnus XIV.—CENTAUREA (Linn.), Knap-weed. 
226. C. NIGRA (Linn.) 
This plant is met with occasionally—Wideford 
brae, Dingesnowe, Westray, &c.; fairly common in 
Sanday and Burray. 
227. C. Cyanus (Linn.), Corn Bluebottle. 
Stray plants occur here and there among oats. I 
don’t think, however, it is a native. It is found in 
Caithness.
