The Scottish Natiiynlist. 
the wet-ground plant — the difference again being due to 
local causes. Mr. F. Tovvnsend also, who has looked over ray 
Shetland Ranunculi^ suspects, from observations on these pumilua 
forms in Scotland and elsewhere, that "they are but states caused 
by situation^ climatic conditions," etc. I have not, however, 
grown this form yet in cultivation. 
R. acris L. — This extends from north to south, but seems 
confined to the sand tracts, and to dry, grassy hillsides near the 
sea. 
NymphOBa alba L. — Recorded from one locality by Edmond- 
ston ; it also occurs near Walls in Lunga Water, Bunya Water, 
and in a small loch near Brunatwatt. 
% Papaver Lamottei Bor.— D. Field at Exnaboe, near 
Sumburgh. Only the aggregate F. diibtum previously recorded. 
t Sinapis alba L.— W. A v/eed in cultivated fields. 
X Subularia aquatica L. — W. Rather abundant in a quiet 
corner of Bardister Loch. 
Cochlearia officinalis L. — D. On the shore at Spiggie ; 
this is the first time that I have seen the typical plant in the 
Islands. 
t Arenaria serpyllifolia L.— D. On dry banks on both 
sides of Quendal House ; and in a stubble field at Exnaboe. 
% Radiola linoides Gmel.— D. Moor at Skelberry ; moor 
by Brue Loch. 
X Geranium Robertianum L. — D. Abundant on the 
stony shore near Boddam ; the locality was pointed out by 
Mr. Isbister. 
Callitriche stagnalis Scop. — D. I met with this for the 
first time in a running ditch at Bakkasetter. 
X Arctium intermedium (Lange) ?— D. In grassy places, 
on Sumburgh Links, Only the old aggregate, A. Lappa^ which 
includes our four species^ is recorded in Top. Bot. Owing to 
their immature condition, I could not determine the plants with 
certainty. I believe it to be referable to the above, though 
possibly it may belong to A. nemorosu?n. 
Sonchus oleraceus L. — D. A garden weed at Boddam ; 
certainly a very uncommon plant in Shetland.
