glandular articulate hairs. This species grows in dense tufts, 

 the prostrate stems slender, often of considerable length. 

 Leaves narrow, simple or 3-lobed ; lobes acute. Flower-stems 

 with few leaves. Common in the North of England and Scot- 

 land, and elsewhere in Europe. 8. ccespitosa, an indigenous 

 species with obtusely lobed leaves and fewer barren shoots ; 

 8. muscoldes, S. Androsacea, and a host of other Alpine species 

 belong to this section ; and $. ceratophylla, a very handsome 

 allied species of dwarfer growth, with rigid sharply-cut leaves 

 and relatively large white flowers, is a native of South-western 

 Europe. 



7. 8. Aizoon.A dwarf herb less than a foot high with 

 rosulate oblong or ligulate leaves margined with sharp teeth 

 and a grey incrustation, and pinkish white flowers. A native 

 of the Alps of Europe. This and many other species with in- 

 crusted leaves are more curious and interesting than ornamental. 

 8. Cotyledon has tall branching flowering stems 2 to 3 feet high 

 and white flowers ; and 8. aretioldes is a diminutive plant 

 about 2 inches high with glandular spa thulate leaves and few 

 yellow flowers. Both are found in the Pyrenees. 8. Andr6wsii 

 and 8. Guthrieana are hybrids, between this and th.e umbrd&ce 

 section.

 Leaves cordate-ovate, acute, one to two inches long, on slender
