Perennial. Rootstock tufted or very shortly creeping. Barren 

 shoots very long, trailing or arching, at length rooting. Flowering 

 Stems not rooting at the base, erect or ascending. Leaves stalked, 

 ovate or deltoid-ovate, subcordate, slightly acuminate, acute, doubly 

 or irregularly crenate-serrate. Verticillasters remote from each other. 

 Lower bracts similar to the leaves, but narrower, and with shorter 

 stalks; upper ones generally lanceolate, with a wedge-shaped base, 

 more rarely similar to the lower ones. Calyx puberulent or sparingly 

 bristly-hairy ; teeth deltoid, abruptly acuminated into triangular points, 

 sparingly ciliated or glabrous, and subspinous at the apex, spreadmg, 

 not half the length of the tube; tube slightly curved and oblique 

 at the mouth. Corolla tube rather longer than the calyx, with a con- 

 spicuous very oblique ring of hairs within, slightly curved upwards, 

 without a projecting sac near the base on the lower side, suddenly 

 enlarged toAvards the apex ; upper lip greatly vaulted, obtuse, 

 sparingly hairy ; lower lip with the lateral lobes ovate-acuminate, the 

 middle lobe a little larger, oblong, acuminated into a lanceolate point. 



In woods and on hedge-banks, particularly on chalk and limestone 

 formations. Local, but not uncommon m the south of England; 

 rare in the north, where it extends north to Lancashire and Yorkshire. 

 It has occurred in Scotland, but is scarcely deserving to be considered 

 even as a naturalised plant. Rare, and very local in Ireland, where 

 it is nearly confined to the east of the island. 



England, [Scotland,] Ireland. Perennial. Spring, early Summer. 



Rootstock many-headed, emittmg numerous wiry radical fibres and 

 producing flowering and barren stems, the latter in autumn attaining 

 the length of 1 or 2 feet, and growing much in the same way as those 

 of Vinca major. Flowering stems 9 inches to 2 feet high, more or less 

 flexuous towards the base. Lamina of the leaves 1 to 2}j inches long. 

 Verticillasters 6 to 10 flowered. Bracts l^toB inches long, the upper 

 ones sometimes very narrow. Calyx yellowish-green. Corolla ^ to 

 1 inch long, yellow, the lower lip bright yello^v', with reddish-brown 

 spots and streaks; vipper lip considerably more than half the length 

 of the corolla; tube very short. Anthers destitute of the hairs which
