and more distinctly amplexicaul. Flowers shortly stalked, at first 

 a|)|)earing to be in a head, until the two or three helicoid racemes of 

 which tiie inflorescence consists lengthen and straigliten, remaining 

 only slightly recurved at the apex, and attaining the length of 1 to 8 

 inches. Calyx about ^ inch long, increasing to rather more than ^ 

 inch. Corolla | inch long, at first rose-colour, afterwards brilliant 

 blue, fading to purple ; tube white ; thi-oat dull red. Stamens ex- 

 serted or included. Calyx enlarged and inflated in fruit, with the 

 segments connivent. Nucules smooth and shining, black, rounded 

 at^ the apex. Plant pubescent, the radical leaves at length rough to 

 the touch, but not prickly. Mr. F. Stratton (to whom 1 am indebted 

 for fresh specimens of the Isle of Wight plant) tells me that this 

 plant sometimes occurs Avith large confluent blotches in the leaves. 



Perhaps it would be better to discard the name P. angustifulia for 

 that of P. azurea, as the former name on the Continent is more gene- 

 rally applied to P. tuberosa, Schrank than to the jilant described 

 above, though Fries and Godron agree with British botanists in 

 limiting it to our plant. Doubtless the two forms differ only as sub- 

 species, so that P. angustifolia might be retained as the designation of 

 the super-species.

Radical leaves oval or ovate-oval, the exterior ones abruptly con- 

 tracted at the base into the broadly winged petiole, the inner ones 

 more gradually attenuated; all somewhat abruptly acuminated and 

 acute at the apex, marked on the upper surface with blotches and specks 

 of greenish- white, the larger blotches sometimes slightly confluent; 

 lower stem leaves oval, abruptly attenuated into the indistinct petiole ; 

 uppermost ones oval-ovate, sessile, slightly decurrent. Corolla tube 

 elabrous within below the circle of hairs in the throat. I'lant rather 

 softly pubescent, none of the hairs glandular, but those on the stem 

 and mature radical leaves slightly vulnerant.

Very similar to P. angustifolia, of which some authors consider it 

 merely a variety. The leaves, however, are always broader, the stems
