UMBELLIFERdE. 
Hydrocotyle vulgaris, L. “ I, II., III.,” IV., Y., YI., YII. The ordinary 
form abounds nearly everywhere on the shores of lochs (ante, fig. 36). 
At Barlockhart Loch there occurred a floating form having stems 
from 30 to 50 inches long, with leaves only about \ inch in diameter 
and very thin. 
Apium nodiflorum, H. G. Reiclib. Y., YII. Scarce, seldom seen as a 
constituent of a loch flora. 
Apium inundatum, H. G. Reichb. “ I.,” IY., Y., YI., YII. Sometimes very 
abundant, but always in water that is not very peaty. It usually 
occurs from the margin to 3 feet and occasionally even to 6 
feet deep, reaching the surface from even the greatest depth. In 
places where the water has retreated, the seedlings sometimes grow 
so thick as to cover the mud with a sward, but their further develop- 
ment in an aerial environment is restrained. 
Carum verticillatum, Koch. IY., Y., YI. This is one of the character- 
istic plants of the lowland parts of Galloway in wet meadows, moors, 
and about the shores of lochs (fig. 27). 
Cicuta virosa, L. Y., YII. As a member of a loch flora, I have only 
observed this plant at Carlingwark Loch, where it is abundant, and 
at Otterston Loch (fig. 56). 
Sium angustifolium, L. ( = $. erectum, Huds.). [YI. — J. M‘A.], YII. 
Always scarce. 
CEnanthe crocata, L. “ I.,” IY., Y., YI. In the lowland Areas this is a 
common plant on the marshy shores of lochs. It occurs in Area YII., 
but not at the lochs. 
Angelica sylvestris, L. IY., YII. Occasionally on marshy shores. 
RUBIACEiE. 
Galium palustre, L. “ I.,” IY., V., YI., YII. Frequent on the marshy 
shores of lochs (fig. 30). 
Y ALERT AN ACEiE. 
Yaleriana officinalis, L. IY., Y., YI., YII. Sometimes found at the 
marshy shores of lowland lochs. In Area I. it is very rare at the lochs. 
COMPOSITE. 
Eupatorium cannabinum, L. “ II.,” YI. Only observed about the lochs 
of the Mochrum district (p. 139). [Often found in damp places by 
the seashore of Wigtownshire and Kirkcudbrightshire. — J. M‘A.]
