 It flowers in July and August. Native of Germany, Swit- 

 zerland, Geneva, Austria, and Piedmont. 



6. Digitalis Ferruginea; Iron-coloured Foxglove. Calicine

 bearded. Stem strict, even, six feet high ; leaflets sessile, lan- 

 ceolate, even, marked with lines, quite entire ; flowers in an 

 upright raceme from each of the upper axils ; bractes linear-

 upper leaves of the calix approximating ; corolla a little 

 longer than the calix, pubescent, yellowish within ; the two 

 upper divisions obscure, the side ones sharp, the lowest 

 longer ; stamina flexuose, without any rudiment of a fifth ; 

 style the length of the flower, which expands in June, and

 about Constantinople. 



7. Digitalis Obscura. Willow-leaved Foxglove. Leaves 

 linear-lanceolate, quite entire, growing together at the base. 

 Stem undershrubby, with a few opposite branches ; flowers 

 on terminating racemes; corollas drooping, obtuse, yellowish 

 within, reticulated, and rufous at the bottom, pale rufous on 

 the outside, especially at the back ; upper lip half cloven 

 and recurved, lower three-parted, the middle part a little 

 longer than the others. It flowers in July and August ; and 

 it a native of Spain. 



8. Digitalis Canariensis ; Canmy Shrubby Foxglove. Cali- 

 cine leaflets lanceolate; corollas two-lipped, acute; stem 

 shrubby. It rises sometimes four, and even five or six feet 

 high, dividing into several branches ; leaves lanceolate, rough, 

 nearly five inches long, and two broad in the middle, gradu- 

 ally decreasing to both ends, having a few short serratures 

 on their edges, placed alternately on the branches, each of 

 which is terminated by a loose spike of flowers, nearly a foot 

 in length : they are of an orange colour, intermixed with 

 yellow, and are shaped somewhat like the flowers of Acanthus. 



Native of the Canary Islands. It begins to Hower in May, 

 and there is generally a succession of flowers on the same 

 plant till the winter puts a stop to them, which renders the 

 plant more valuable. It is propagated by seeds, which 

 should be sown in pots filled with light earth, in the autumn, 

 toon after the seeds are ripe. Those pots ought to be 



plunged into an old bed of tanner's bark, the heat of which 

 is exhausted, and in mild weather the glasses ought to be 

 drawn off to admit the air ; but in hard rains and frosts they 

 must be kept on, to protect the seeds.from both which fre- 

 quently destroy them when exposed in our climate. The 

 plants will come up in the spring, and should enjoy the free 

 air in mild weather, but must be protected from the cold. 

 When these are large enough to transplant they should be 

 each planted into a separate small pot tilled with light earth, 

 and placed under the frame till they have taken new root, 

 and ought then to be gradually inured to the open air. They 

 must have a sheltered situation during the summer, but iu 

 the winter must be placed in a green-house, for they will not 

 live abroad in England. They must not be kept too warm 

 and close in the house, for they only want protection from 

 the frost, and in mild weather require abundance of free air 

 and frequent waterings. 



9. Digitalis Sceptrum ; Madeira Shrubby Foxglove. Cali- 

 cine leaflets subulate; bractes linear, longer than the flowers ; 

 corollas obtuse ; leaves elliptic, serrate ; stem shrubby. This 

 is a very handsome plant, the branches of which are rough 

 with hairs ; peduncle terminating the branch, solitary, round, 

 upright, a hand or more in length, porous on the inside, end- 

 ing in an ovate spike, with the flowers hanging down. It 

 (lowers in July and August. Native of Madeira, in woods. 

 For the propagation and culture of this plant, see the preced- 

 ing species. 



10. Digitalis Orientalis ; Oriental Foxglove. Caliciiie 

 leaflets acute; leaves oval-lanceolate, nerved. Root leaves 

 many, smooth ; among these arises the stalk about a foot 

 high ; the leaves on it are smooth, from four to five inches 

 long, and one inch and a half broad in the middle, half stem- 

 clasping; spike terminating, short, loose : corollas yellow, al- 

 most as large as those of the fifth species, but shorter It flow- 

 ers in May, and the seeds ripen in Autumn. Native of Tartan ; 



11. Digitalis Cochin-chinensis. Leaves lanceolate, rough ; 

 flowers solitary, axillary; calices acute; corollas obtuse,
