 Billot, Fl. Gall, et Germ. Exsicc. No. 585. 



Hootstock almost woody above, with a deeply-buried fusiform 

 fleshy enlargement. Radical leaves on long petioles, lanceolate or 

 narrowly elliptical, attenuated or ovate and abrupt at the base, 

 serrate-crenate ; stem-leaves numerous, sessile (except the lowest, 

 which are similar to the radical ones, but much smaller), strap- 

 shaped, acute, nearly entire ; uppermost ones lanceolate-acuminate. 

 Heads globular in flower, ovoid in fruit. Bracts ovate or ovate- 

 lanceolate, acute or acuminate. Calyx-segments broadly lance- 

 olate-triangular. Segments of the corolla at length separating 

 throughout. Capsule usually 3-celled. 



On chalk downs and in chalk-pits. Local. Not uncommon in 

 Hampshire, Sussex, Surrey, and Wilts ; also reported from Kent, 

 but not on recent authority ; a specimen was sent to the Botanical 

 Society of London from Shef&eld on the authority of Mr. L. G. 

 Lyon, but this station is very improbable. 



England. Perennial. Late Summer. 



Hootstock with a fleshy tuber about the size of the little finger, 

 usually buried 2 or 3 inches below the surface ; above the tuber it 

 is contracted, and usually divides at the top into several heads, 

 which send up flowering-stems or tufts of leaves. Radical leaves 

 variable in form, the petiole longer than the lamina. Stem 3 inches 

 to 2 feet high, erect, leafy at the base, the leaves becoming more 

 distant and much smaller towards the upper part. Heads ^ to 

 1 inch long in flower, 1 to 1^ inch in fruit. Plowers deep-blue, 

 curved upwards in bud, but the segments at length separating. 

 Styles exserted, pubescent, bright-blue, with 3 or more rarely 2 

 stigmas. Plant glabrous, or with a few hairs on the margins of the 

 petioles, leaves, and bracts. 



Hound-headed Hampion.
