for example, it covers a large area of the water and presents 
a magnificent spectacle when in flower. 
Ranmiculus peltatus, Schrank, IV., V., VI., VII. W^idely dis- 
tributed and sometimes very abundant. 
Ranunculus heterophjllus, Weher^ IV., V. Occasionally very 
abundant ; in Loch Ken, for instance, it overgrows consider- 
able tracts of shallow water at the margin, of the loch, and 
when in flower is extremely picturesque. 
Ranunculus Lenormandi, F. SchuUz^ V. On mud at the margin of 
lakes, but scarce. 
Ranunculus hederaceus, L. I., very scarce. VII., frequent on the 
muddy shores of lochs. In Areas IV., V., and VI. it is frequent 
about streams, etc., but is seldom seen at the lochs. 
Ranunculus sceleratus, />., VII. On muddy shores, but very scarce. 
Ranunculus Lingua, Z/., V., VII. On marshy ground about lowland 
lochs ; restricted in distribution, but abundant where it does 
occur. 
Ranunculus Flammula, /.., I., II., III., IV., V., VI., VII. Normal 
forms are abundant nearly everywhere below 1000 feet above 
sea-level. 
Ranunculus scoticus, Marsh. ^ I., IV. Abundant on the shores of 
mountain lochs. 
Ranunculus Flammula, L. A prostrate form rooting profusely 
at the nodes, similar to var. pseudo-rep tans but much larger, 
is sometimes found upon the stony shores of lochs in all the 
Areas, but is especially abundant at Loch Ken. 
Ranunculus Flammula, L., var. pseudo-rep tans, Syme, VII. 
Scarcely distinguishable from the true R. reptans. It has, 
however, a broader achene which is more suddenly contracted 
into a beak than R. reptans, and the stem structure differs 
in having 3 vascular bundles, instead o£ 5-7 as in R. reptans. 
Ranuncuhis reptans^ Z., VII. On flat, exposed sandy places, that 
are either bare or covered with short turf, all around Loch Leven. 
Ranunculus Flamnmla, L., var. natans, Pejs., IV. Submersed, with 
a stem 12 to 30 inches long, having a few radical leaves 3 to 
8 inches long, with a small spathulate or elliptical lamina | to 
1 inch long. A number of roots and a fascicle of leaves, similar 
to the radical leaves, but smaller, are given off from every node. 
It is very abundant in the neighbourhood of Lochs Recar, 
Ballochling, etc. 
Caltha palustris, Z., L, II., IIL, IV., V., VI., VII. An abundant 
plant about lowland lochs, especially in Area VII. 
Caltha palustris, L., var. minor, Syjue^ I., IV. On the shores of moun- 
tain lochs. No doubt this is a depauperated form of C. palustris.
