and treatment to those recommended 

 for D. austriacum. Division. 



Doronicum Pardalianches (Leopard's- 

 lane). A coarse perennial, 1^ to 3 ft. 

 high. Flowers, in spring and early 

 summer ; yellow, usually 3 to 5 on 

 each stem ; rays numerous, very nar- 

 row. Leaves of root heart-shaped, 

 hairy, stalked ; of stem, few, ovate, 

 lower ones stalked, upper sessile and 

 clasping. Hoots fleshy, forming at 

 intervals small tubers about the size 



of a bean. Central Europe. 



Suitable for rough and wild places 

 only, under trees or otherwise, and 

 in any soil. Division. 



Doronicum plantagineum (Plantain 

 D.) A vigorous herb allied to the 

 previous species, but with larger 

 flowers, and leaves not heart-shaped, 

 but varying, either entire or irregularly 

 toothed ; 2 to 3 ft. high, flowers, in 

 spring and early summer; yellow, 

 usually solitary on a terminal 

 peduncle, sometimes, though very 

 rarely, 2 or 3 on a stem. Leaves, of 

 root, ovate or oval, stalked, un- 

 evenly toothed; stem-leaves nearly 

 entire, lance-shaped, narrower than 

 those of the previous species. Central 



and Southern Europe. Like the 



preceding, not desirable for any but 

 semi- wild spots. Division. 



Draba aizoides (Seagreen D,) A 

 brilliant dwarf rock plant, 2 to 3 in. 

 high. Flowers, in spring ; bright 

 yellow, in terminal racemes ; stamens 

 about as long as the petals; scapes 

 naked, smooth. Leaves, narrow, 

 lance-shaped, keeled, ciliate, arranged 

 in neat rosettes. It rarely ripens 

 seeds. Found in one locality in South 

 Wales, and on rocky and gravelly 

 spots on mountains in Central Europe. 



The rock-garden, in gritty soil, 



crevices in mossy old walls and ruins ; 

 occasionally, in very tine and well- 

 drained sandy soils, it thrives very 

 well in borders, but in this case 



it ought to be protected from the 

 encroachments of coarser plants. 

 Division and seed. 



Draba Aizoon (Evergreen D.) Allied 

 to the previous species, but a more 

 vigorous grower, with the leaves 

 broader and of a darker green, 

 arranged so as to form a large and 

 complete rosette, from which spring 

 the flower-stems, about 5 or 6 in. 

 high. Flowers, in spring ; pale yellow, 

 produced in terminal racemes ; scape 

 naked, villous. Leaves, linear, acutish, 

 keeled, stiff, ciliated. It ripens seed 



freely. Mountains of Carinthia. 



The positions and treatment recom- 

 mended for the preceding species will 

 suit this also. 



Draba alpina (Alpine D.) An arctic 

 species, 2 to 3 in. high. Flowers, in 

 spring; yellow, rather smaller than 

 those of D. aizoides, in terminal 

 racemes ; scape naked, pubescent. 

 Leaves, lance-shaped or ovate, dark 

 green, flat, smooth. N. Europe and 



N. America. A somewhat delicate 



subject, and best adapted for pot cul- 

 ture, or well-drained chinks in rock- 

 work, in sandy loam. Seed or division. 

 Draba ciliaris (Large Yellow D.} 

 One of the largest-flowered and finest 

 of the yellow Drabas, 3 to 4 in. high. 

 Flowers, in spring and early in sum- 

 mer ; yellow. Leaves, densely clothed 

 with soft spines, in rosettes. Probably 



a variety of D. cuspidata. Alps. 



Eockwork. Seed or division. 



Draba ciliata (Ciliated Draba). 

 One of the finest of the white-flowered 

 kinds, and resembling a miniature 

 plant of Arabis albida.; 2 in. high. 

 Flowers, early in summer ; white, few, 

 closely set ; sepals, green, oval. Leaves, 

 somewhat leathery, smooth, with a 

 cartilaginous margin, slightly toothed 

 and fringed with stiff hairs ; those of 

 the rosette obovate, shortly pointed ; 

 those of the stem oblong, usually two 

 or three in number. Pods linear;
