Caithness. The Wick sort is slender, and sparingly branched 
with yellow flowers, but the Newton (14 miles distant) 
specimens have large leaves, spotted flowers, and are much 
more branchy. 
Suxifraga tridactylites (Linn.).—Found abundant at the 
mouth of the Burn of Dunnet, near Dunnet Head. It grows 
on braes, close to the sea-sand. For an interesting dispute 
about this plant, see Smiles’ “ Life of Dick.” 
Thalictrum majus (Cranz).—Specimens of the supposed 7’. 
moajus having been sent to Bennet, the latter says in “ The 
Journal of Botany,’ 1882 :—* Some slight doubt may attach 
to this plant—the fruit being too near ‘minus,’ but the 
exposed and northern situation may have stunted the develop- 
ment of the fruit late in autumn.” In 1885 Messrs Hanbury 
and Fox took a botanical tour through Caithness, and had those 
plants pointed out to them at Reay. They thought the 7. 
majus to be only luxuriant specimens of 7. maritimum; the 
difference being due to shelter and soil—the stunted form 
growing on the top of a hillock and the larger in the 
sheltered hollow at its side. 
fanunculus aquatilis (var.)—Of the various species or 
varieties that have at one time or other been included under 
fi. aquatilis, there is a variety growing in a pond at Shore- 
lands (a mile or so from Wick) which the late H. C. Watson 
called &. trichophyllus (Chaix), and another in the ditches 
between Wick and Staxigoe—which corresponds to the de- 
scription of &. Baudotii (Godronii), var. confusus, in Hooker’s 
“Flora.” The Staxigoe specimens vary much, and on com- 
paring them with the descriptions and figures in “ Sowerby’s 
English Botany,” one seems to have a choice between 
calling them intermediate forms of &. Drouetii (Schulz), 
hi, Baudotii vulgaris, and R. Baudotii confusus, or supposing 
that the differences between those is imaginary. Specimens 
from Sibster (14 miles from Wick), which appear identical 
with the Staxigoe ones, have been named £&. heterophyllus 
(Fries) by A. Bennet. 
Ranunculus arvensis (Linn.)—The only specimen ever 
found in Caithness. It was probably introduced with 
garden seeds, as it grew in a bed of carrots. 
Sisymbrium Sophia (Linn.)—Once found by Dick on a 
ballast heap near Thurso,
