DICOTYLEDONES. 37 
Var. salina (Bab.) This variety is met with more 
frequently than the species. 
209. M. MARITIMA (Linn.), Scentless Mayweed. 
A seashore plant which is not uncommon in Deer- 
ness, and no doubt found elsewhere. I sent roots for 
cultivation to Mr Hunnybun, Huntingdon. He says, 
“One of the plants you sent me is evidently matricaria 
maritima.” I gathered a few plants of imodora in 
Fair Isle, which I take to be maritima, but the 
ligules are yellow. 
210. M. CHAMOMILLA (Linn.), Wald Chamomile. 
This plant is probably introduced, but several 
escapes have become naturalised. Found it growing 
abundantly in a sheltered hollow in Beaquoy, Birsay. 
Genus CV.—TANACETUM (Linn.) 
211. T. vuLGARE (Linn.), Tansy. 
Introduced, but now found frequently in yards 
and about farm houses, and used medicinally. 
Genus CVI.—ARTEMISIA (Linn.) 
212. A. VULGARIS (Linn.), Mugwort. 
This is a fairly common weed on the boundary 
line between fields. It is known in Orkney as “ bul- 
wands,” in East Mainland as “grobbie.” The tops of 
‘this plant were formerly used instead of hops for 
flavouring ale. 
Genus CVII.—TUSSILAGO (Linn.) 
213. T. Farrara (Linn.), Colt’s-foot. Common. 
A most difficult weed to eradicate when once 
established.
