A. sarmentosa. — A pretty Himalayan 

 species forming dense silvery rosettes of 

 oblong spoon-shaped hairy leaves, and 

 numerous runners with tufts at the end. 

 Flowers in May and June, bright rose, 

 with a white or deep rosy eye, 10-20 in 

 an umbel on an erect scape 6-9 in. high. 

 Closely related to this species is A. sem- 

 pervivoides, a native of Western Thibet. 

 It may be distinguished by the leaves 

 being curled up into a cone, and by the 

 bright purple flowers. 



Culture and Propagation. — These 

 require sunny sheltered chinks of the 

 rookery in rich sandy loam and peat. It 

 may be increased by pegging down the 

 runners and covering with rich soil to 

 induce the formation of roots. In wet 

 winters u sheet of glass may be placed 

 over the plant to prevent wet lodging in 

 the hairy rosettes. 



A. septentrionalis (A. coronopifolia). 

 A charming Russian biennial with flattish 

 rosettes of smooth, lance-shaped, dis- 

 tantly toothed leaves. Flowers from 

 April to June, pure white, on umbels 

 borne on stalks about 4-6 in. high. 



Culture dc. as above. In rich, free, 

 sandy loam and peat in the rockery this 

 species flourishes, and sows its seeds 

 freely. The new seedlings replace the 

 old plants naturally. 



A. villosa {A. penicillata). — A pretty 

 alpine and Pyrenean species 2-4 in. high 

 with dense rosettes of narrow oblong 

 leaves covered with a soft whitish down 

 chiefly on the under surface. Flowers in 

 May, rose or blush, about j in. across, with 

 a deeper coloured centre, and a honey-like 

 perfume. 



Culture dc. as above. Between pieces 

 of limestone in sandy loam in the rockery. 

 "When established the flowers are produced 

 in great profusion. 



A. wulfeniana.— A rare dwarf free- 

 growing Austrian species about 2 in. high, 

 forming dense rigid tufts or rosettes of 

 deep green oval pointed leaves. Flowers 

 in summer, large, vivid rose or purple- 

 crimson. There is a variety called 

 Pacheri. 



Culture dc. as above. Deep sandy 

 loam and peat in the rookery. 



DOUGLASIA. — A genus containing 

 a few species of tufted or cushion-like 

 smooth or hoary herbs with imbricated, 

 clustered and spreading leaves, awl- 



shaped or oblong-lance-shaped, entire. 

 Flowers at the ends of the branches or 

 axillary, solitary and sessile or stalked, 

 sometimes clustered in sessile umbels, 

 yeUow or red. Calyx beU-shaped 6-cleft 

 to the rhiddle. Corolla hypogynous, 

 salver-shaped, constricted at the throat, 

 and having 5 obovate oblong blunt im- 

 bricated lobes. Stamens 5 attached to the 

 throat of the corolla. Ovary superior. 



Culture a/nd Propagation. — Doug- 

 lasias being so closely allied to the Andro- 

 saces and having the same habit of 

 growth may receive the same treatment 

 in the rockery. A deep rich sandy soil 

 composed of loam, peat, and leaf mould 

 wUl suit them, and they may be propped 

 up with pieces of stone so as to drain the 

 water from them. A fresh stock of plants 

 may be increased by carefully dividing the 

 tufts in early autumn or in spring. Seeds 

 may also be sown when ripe in cold 

 frames, in which the young plants may be 

 grown on in pots until sturdy enough for 

 the open air. 



D. tevigata. — A tufted perennial 

 native of the Oregon Mountains, with 

 rosettes of linear or oblong lance-shaped 

 acute leaves ^| in. long and more or less 

 toothed on the margins. Flowers in 

 spring and autumn, rosy-pink, ^| in. 

 across, 2-5 on stalks about 1-2 in. long. 



Culture dc. as above. 



D. nivalis. — A native of the Rocky 

 Mountains with rigid hoary somewhat 

 verticillate branches, and tufts of bluntly 

 linear somewhat stem - clasping, hairy 

 leaves. Flowers in April, pink, on long 

 stalks. 



Culture dc. as above. 



D. vitaliana (Androsace vitaliana ; 

 Oregoria vitaliana). — A native of the 

 Alps and Pyrenees 1-2 in. high, with 

 linear, acute, greyish - looking leaves. 

 Flowers from May to July, rather large, 

 rich yellow, scarcely rising above the 

 leaves. 



Culture dc. as above. Moist yet well- 

 drained sandy loam in sunny parts of the 

 rockery between pieces of limestone or 

 sandstone. Increased by seed or careful 

 division. 



CORTUSA (Bear's-Ear Saniclk).— 

 A genus containing one or two species 

 of downy scapigerous herbs with perennial 

 rootstocks. Leaves long-stalked, roundish,
