LIST OF THE PLANTS. 
In a future contribution I hope to deal especially with the 
internal and external morphology of the plants here enumerated ; 
such matters are therefore excluded from the present pages. The 
occurrence of the plants in each of the three areas under discussion 
is indicated by the numerals after the authority, viz. : — 
I. The Ness area. II. Island of Lismore. III. Lochs at 
Nairn. 
ranunculaceh:. 
Ranunculus hederaceus, L. I. Very scarce. 
Ranunculus Flammula, L. Normal forms. I., II., III. 
Abundant everywhere below 1000 feet. 
Ranunculus scoticus , Marsh. I. Abundant about the shores 
of lochs over 1000 feet above sea. This is merely a 
depauperated form of R. Flammula, L. From the non- 
flowering specimens, 3 inches or less in height at great 
elevations, every stage to the normal lowland forms may 
be obtained as one proceeds towards sea level. 
Ranunculus circinatus, Sibth. II. Very scarce. 
Caltha palustris, L. I., II., III. Abundant in lowland 
situations. 
Caltha palustris, var. minor , Syme. I. The remarks to 
R. scoticus , Marsh., apply equally well to this depauperated 
form of C. palustris. 
nymphhiaceh:. 
Castalia speciosa, Salisb. I., II. Abundant in places where 
the water is less peaty. 
Castalia speciosa, Salisb ., var. minor, DC. I. In peaty hill 
lochs, often growing on mud. An intermediate form also 
occurs in peaty lochs at less elevation; the leaves are 
smaller than the type and purplish, lobes more divergent 
and acute, reticulations below more prominent. These 
variations from the normal are probably due to environ- 
ment.
