202 ALPINE FLOWERS. Part II. 



rock-garden, will suit it to perfection, and, when sufficiently 

 plentiful, it will no doubt prove one of our most valuable border- 

 flowers. A native of North America. 



DEABA tJZ.OT.'D'E&.—Seagreen Whitlow-Grass. 



This may be taken as the typical species of the Golden 

 Drabas ; it is indigenous to Britain, but only found in one 

 locality in South Wales, where, let us hope, its inaccessible po- 

 sition in many instances will protect it from the hand of the 

 destroyer. In growth it does not exceed three inches in height, 

 and when planted on the slope of a sunny border, in sandy soil, 

 which it loves, it forms a dense golden carpet in the early part 

 of March. It does not ripen seed so freely as the following 

 kind, but increases readily by division, and in these two respects 

 we have a very marked and tangible distinction from the follow- 

 ing otherwise closely allied species. A very neat plant for 

 rockwork, and also an attractive subject for naturalising on 

 moist old walls, mossy ruins, &c. 



DRABA KLZOOTH.— Evergreen Whitlow-Grass. 



A NATIVE of the mountains of Carinthia, closely allied to the 

 previous species, but a much more vigorous grower ; the leaves 

 are broader and of a darker green, and arranged so as to form 

 a most complete rosette, not unlike the Sempervivums. From 

 the centre of this rosette it sends up a stem five or six inches 

 long, bearing numbers of bright-yellow flowers, and ripens its 

 seeds freely. Draba boeotica I am disposed to consider a narrow- 

 leaved form of the above. In the cultivation of both it must be 

 borne in mind that, unlike D. aizoides, the old stems will never 

 throw out roots, consequently they cannot be classed as spreads 

 ing plants. They increase freely from seed, some of which it 

 would be interesting to sow on old walls and ruins, with a view 

 to naturahsing them in these positions. They are most effective 

 when grown in small pots, in which they might, for early spring 

 use, be plunged in a close line, say round the margin of a raised 

 " pin-cushion " bed, with admirable effect. 



DRABA KLSINK.— Alpine Whitlow-Grass. 

 An arctic plant, with dark-green, smooth, somewhat ovate leaves, 

 growing about two inches high, and producing bright golden
