JOUENAL OF THE EOYA1 HOBSICULTUBAX SOCIETY. 



S. Cymbalaria, L. — Leaves reniform ; flowers bright yellow. 

 Hab. Himalaya and Caucasus, in damp and shady places. 



S. Sibthorjpii, Boiss. et Spinner. — This diners only slightly 

 from the above. 



Sect. Tridactylites, Haw. 



Nearly all of this class are merely botanical curiosities, and 

 on this account hardly worth growing, though they are very 

 interesting. 



S. petraa, L. — Leaves fleshy, palniatifld ; flowers pedicellate, 

 white. Hab. The Alps, in very high altitudes, in dark and damp 

 caves, and the north side of rocks. Prop Lira: ion by sec is. 



S. adscendens, S. tridactylites, and several others, are all very 

 interesting. 



Sect. Nepheophyllum. Gaud. 



These are very distinct, and some of them very showy ; they 

 differ from the preceding by their deciduous bulbiferous habit. 

 They prefer shady and damp positions, slightly protected. In- 

 creased by bulbs. 



S. granulata, L. — Leaves palmate, hairy ; flowers large 

 white. Hab. The Alps, and many parts of this country. The 

 variety flore-pleno is a pretty garden form with double flowers ; 

 very useful for cutting. 



S. ut::j. L. — Leaves palmate : flower white. Hab. Spain. 



S. irrigua f M.B. — Leaves palmate, o-parted ; flowers white. 

 Hab. Caucasus. 



Sect. Trachyphyllum, Gaud. 



A great many of these are not only very interesting, but also 

 very beautiful. Unfortunately, very few are at present under 

 cultivation. They are easily increased by seeds and division, 

 and succeed best in a damp and shady position, in light sandy 

 loam. 



S. flagellaris, Wild. — Leaves spatulate, in rosettes, often 

 ciliate ; flowers yellow. Easily increased by division of the 

 stolons. Hab. the Caucasus. 



The following are equally pretty : — S. bryoidcs, S. bronchi- 

 alis, S. tricuspidata, S. aspera, and S. aizoides.
