232 WINDOW GARDENING. 



55. Sempervivum Calif ornicum, a larger species; leaves are of a dark green 

 color, with reddish margin and dark points. 



56. Silene alpestris, a very fine plant of dwarf habit and pure white flowers. 



57. Silene maritimafl. pi. The leaves of this species are of a glancous color, 

 and the flowers are like small snowballs. 



58. Soldanella alpina, a lovely little plant of an interesting appearance, with 

 leathery, shining, roundish leaves and beautiful blue bell-shaped, fringed 

 flowers. 



59. Thymwzerpillifoliumfol.var., the variegated Thyme. 



60. Viola cornusa, the Pyrenean Violets with very large blue and white flow- 

 ers which appear numerously during the summer season. 



Finally, we observe, that in a collection like the preceding one, many plants 

 could be added, which would match well with the Habitus of Alpine plants but 

 which would anyhow require another treatment ; for instance, a warmer place 

 for the winter season, while others are in a resting state during the summer.
