SILENE. 



beautiful as was the original 8. uniflora, that called S. u. grandiflora 

 bears flowers of almost twice the size and quite twice the freedom ; it 

 seems uncertain whether this is not the truer type of the species. The 

 race stands quito close to its cousin, Schizocodon, and will inter- 

 breed — though most careful division (if you dare) of established clumps 

 (if you can achieve them) will always be the readiest way to increase 

 your stock of a treasure so rare and subtle. 



Sibbaldia procumbens and S. maxima (or cuneata) are worth- 

 less little greenery-yallery carpeters, between Potentilla and Alche- 

 milla, but more reminiscent in effect of a thready and starveling 

 Alchemilla. They may be grown, if wanted, on non-calcareous rock- 

 work near water in cool shady and well-drained places. But for 

 precautions so choice most gardeners will prefer plants more choice 

 to match. 



Sibthorpia europaea is a valueless half-hardy Scrophulariad 

 from Western Europe. 



Sida napaea and 8. dioica are two big malvaceous weeds 

 from America, with white flowers. They are for the seed and treat- 

 ment of the next, but much less valuable. 



Sidalcea. — These tall Mallowy wands belong more rightly to the 

 herbaceous border ; they will be found in all catalogues — 8. Candida, 

 8. oregana (under the false name of 8. malvaeflora), and 8. Listeri — 

 all bushy handsome things of a yard or more in height, with lavish show 

 of silky pink or white Mallows throughout the late summer. 



Sideritis. — These are woolly-velvety Labiates of the South, 

 requiring great heat and dryness, which they do not requite with any 

 corresponding brilliancy of blossom. Smallish hi habit, and therefore 

 most suitable for the hot rock-garden, are 8. condensata, with stems 

 of 4 inches, and yellow flowers in September ; and 8. euboea, flowering 

 at the same time, on stems two inches taller. Others, rather bigger, 

 for higher places on sunburnt banks, are 8. spinosa and 8. libanotica. 



Sieversia is hardly, if at all, to be distinguished from Geum, either 

 in looks or needs. The names, in catalogues, are often changed. 

 8. anemonoeides is a pretty creeping species from Kamchatka, with 

 solitary fine flowers ; 8. glacialis is hairy and one-flowered also, with 

 golden blossoms that cheer Siberia. And 8. Rossii usually appears 

 in lists as Geum. It has handsome feathered sliming foliage, and 

 brilliant yellow blossoms on long stalks. There is also a quite dwarf 

 variety of this in Tchuchtchuland, called S. R. humilis. 



Silene. — In spite of having lately lost two of its brightest jewels, 

 this huge and artificial family still rotains some valuable rock plants, 

 of dolicate rather than dazzling charm, among hundreds of worthless
