VIOLA CURTISII 13 
rather smaller than the middle lobe; stipules of intermediate and 
upper leaves larger, with spathulate entire middle lobe. Peduncles 
_ very long, upright, straight, slender, glabrous, usually only one or 
two on each subaerial shoot. Flowers very large, 1-1} in. in length, 
generally much longer than broad. Sepals linear or linear-lanceo- 
late, acuminate, glabrous, sometimes ciliate; sepaline appendages 
short. Petals two to three times as long as sepals, bright yellow, 
the two upper ones diverging but often overlapping towards the 
base, lateral and lowest petals marked with deep violet striz, 
lowest petal broad, strongly umbilicate, petaline spur slender, much 
longer than the sepaline appendages. 
A plant of upland grassy places and pastures, growing amongst 
short grass. It is particularly plentiful on Carboniferous Lime- 
stone, but also occurs on Millstone Grit, though apparently much 
less frequently. 
r. Murrayi (nov.var.). This plant differs from typical lutea in 
several respects. The most striking feature is the development of 
nners, which arise in the axils of leaves at the base of the stem 
This is a very well-marked variety. It was collected on the 
sandy shore of Loch Muick by my friend Mr. Cecil Hay Murray, 
eg it. 
Var. amena Henslow, Cat. Brit. Pl. 3 (1829) seems to be 
merely a colour variety of lutea, with whic it agrees in all 
respects except in the possession of blue-violet flowers. Inter- 
mediates between this and true lutea exist, and the wisdom of 
perpetuating the name is doubtful. 
Vv. CURTISIE. 
Perennial plants of maritime sandhills, with subterranean 
slender branching perennial stems. Flower with petals longer 
than the sepals, and with long petaline spur.
