PART II.— SYSTEMATIC LIST OF THE PLANTS. 
RANUN CULACEAE. 
Ranunculus aquatilis, L. IV., Y., VI., VII. Many forms of the aquatic 
Batrachian Ranunculi occur in the lowland non-peaty lochs of the 
districts now under discussion. Occasionally it was quite impossible 
to determine the exact species met with, owing to the absence of 
flowers and fruit, or other data by which the numerous forms are 
distinguished. The species enumerated below I have been able to 
collate with published descriptions. In the local lists contained in 
this paper, when R. aquatilis is given, it will be understood that it 
has not been possible to distinguish the exact species, for the reasons 
just mentioned. All forms are very scarce in Areas I. to III. 
Ranunculus Drouetii, F. Schultz. V., VI., VII. Not very general ; 
occurring chiefly in small lowland lochs. 
Ranunculus Baudotii, Godr. VII. Not common, but occasionally 
abundant. 
Ranunculus circinatus, Sibth. “ II. Very scarce.” VI., VII. Not 
general, but occasionally very abundant : at Kilconquhar Loch, for 
example, it covers a large area of the water, and, with the preceding 
species, presents a magnificent spectacle when in flower (fig. 92). 
Ranunculus peltatus, Schrank. V., VI., VII. Widely distributed, and 
although not a common loch plant, is occasionally very abundant. 
Sometimes a terrestrial form overgrows mud at the margin of a 
loch, as at the west end of Kinghorn Loch. At L. Camilla, Fife, 
there is a curious form with dark spots and blotches on its lobed 
floating leaves, similar to those on the leaves of R. hederaceus ; the 
latter is also abundant at L. Camilla. 
Ranunculus heterophyllus, Weber. IV., V. Occasionally very abundant. 
In Loch Ken, for instance, it overgrows considerable tracts of shallow 
water at the margin of the loch, and when in flower is extremely 
picturesque (figs. 37 and 38). 
Ranunculus Lenormandi, F. Schultz. V. On mud at the margin of 
lakes, but very scarce. [VI. In ditches S. of Lows Warren. — 
J. MW.] 
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.
