Rysadale, Stenness ; Trumland ; Dwarfie Stone ; 
Head of Holland. 
132. E. PARVIFLORUM (Schreb.), Small-flowered 
Willow-herb. Scarce. 
It grows below Upper Braebuster, Deerness, and 
near Hall of Tankerness (1899). Dr Grant found it 
same summer near Stromness; Myre, Sanday. 
133. E. MONTANUM (Linn.), Willow-herb. Common. 
134, E. TETRAGONUM (Curt.), Square-stalked Wail- 
low-herb. 
Some doubt has been expressed as to whether this 
plant grows in Orkney ; but I believe it is to be found 
in several places in St. Andrews. The leaves differ 
much from obscurum. Mr Patrick Neil reports it 
from the Gills of Scapa. 
135. E. opscurUM (Schreb.), Willow-herb. Fairly 
common. 
Ward Hill, Orphir; St. Andrews—several places. 
136. E. PALUSTRE (Linn.), Narrow-headed Willow- 
herb. Not uncommon. 
Bog, Mirkaday, Deerness ; Orphir, &e. 
Var. lineure (Krause). This is a variety sent to 
Mr Ar. Bennett and named by him. Several crosses 
have been found among the epilobiums. I got one in 
peat banks to south of junction of Tankerness and 
Deerness roads—Palusire x obscurum.
