and purple flowers. It is a native of Siberia, not very distinct 

 from the one figured. S. purpurdscens, from Northern India, 

 is the best of this section, but not quite hardy, and very rare. 



2. S. umbrosa. London Pride, None-so-pretty, St. Patrick's 

 Cabbage, This old favourite is so familiar as to render de- 

 scription almost superfluous. Leaves in dense tufts, obovate, 

 crenate, narrowed at the base ; petiole ciliated. Flower-stem 

 leafless, slender ; cymose flowers small, white or pink spotted 

 with red or purple. There are several varieties of this and 

 S. Geum, all of which are referred to one species by some 

 writers. The extreme form of the latter has orbicular leaves, 

 cordate or rounded at the base ; but some of the varieties are 

 intermediate between the two. Both are indigenous in Ireland 

 and South-western Europe. 



3. S. granulata. This species belongs to another distinct 

 section with radical palmately lobed leaves, suberect sepals, 

 and white petals. It is a native, and the only lowland species 

 with the exception of the inconspicuous S.tridactylltes, usually 

 found on walls and buildings, extending to the South of Eng- 

 land. It is distinguished by its granular bulbous roots and 

 petiolate reniform-palmate glandular leaves. Flower-stems 

 about a foot high. There is a double variety in cultivation. 

 S. cernua is a similar but smaller plant, from mountainous 

 districts of the north. 



4. 8. Hirculus. The representative of a group with leafy 

 stems and yellow petals and free sepals. In this species the 

 radical leaves are rosulate, petiolate, lanceolate, and the cauline 

 linear. A dwarf stoloniferous plant with few or solitary yellow 

 flowers. Native of the northern parts of Britain, and widely 

 distributed in Arctic and Alpine Europe, Asia, and North 

 America. 



5. 8. oppositifolia. The type of a section with opposite 

 leaves, furnished with a pore at the tip. The present species 

 grows in tufts. Stems slender, 2 to 3 inches high, thread-like, 

 with a few small glabrous thick dark green leaves, and a com- 

 paratively large solitary terminal purple flower. A native 

 species, and like the last of* very wide distribution. This is a 

 handsome little plant, flowering in Spring from April to June. 

 There is a white and also a pink variety. S. biflora, 8. 

 Kochii, and S. retusa are closely allied species. 



6. 8. %2mokfos. Perennial, with many leafy flowerless 

 shoots, alternate palmately lobed leaves, white flowers, and
