1904-5.] Flora of Scottish Lakes. 
CALLITRICHACE^E. 
Callitriche stagnalis, Scop. I., III. Aquatic and terrestrial 
forms ; scarce ; not seen in very peaty water. 
Callitriche hamulata, Kiltz. III. Scarce. I. Extremely 
abundant in almost every loch ; a dominant plant. Never 
seen here with a rosette of spathulate floating leaves ; all the 
leaves are linear and emarginate. 
Mr A. Bennett of Croydon has written me respecting this 
species as follows : — “It is unusual for this species to occur 
over wide areas without floating rosettes ; but it does occur 
so, without them, here in the south, and then when in the 
water it looks somewhat like C. autumnalis, L., on a small 
scale, but the fruit is very different. I have specimens 
before me that are quite like your plant from 1 Scalloway, 
Shetlands, 1890. R. M. Barrington.’”
