104 Alpine Plants. 
Ranunculus pyrenzus (Alps and Pyrenees). 
Treat like Callianthemum anemonoides. 
Rhododendron lapponicum (Arctic Kegions). 
This requires a somewhat shady position, and 
will do on the north side of a rockery, in peat, rough 
loam, and sand. The plant must be made perfectly 
firm, or it will soon die away when dry weather comes. 
Rhododendron setosum (Arctic Regions). 
Treat like Rhododendron lapponicum. 
Rhodothamaus (syn. Rhododendron) Chamecistus (Alps ot E. 
Europe). 
Where lime is absent, this miniature Rhodo- 
dendron is most useful for the rock-garden. A 
partially shady place suits it best, although it will 
grow in full sun. To succeed with it in sun, the 
plant must either be well established before it is 
planted out, or else it must be shaded from the sun 
by artificial means for some time after it is planted, 
until it has become fairly established. Under such 
treatment the plant will bloom much more freely 
in the sunny than in the shady place, as it is able 
to get the wood well ripened annually, and its buds 
set for the following year, whereas this is less assured 
in the shade. Plant in hard peat and sand, which 
should be pressed firmly against the roots, and top- 
dress twice a year with the same compost. 
Romneya Coulteri (California). 
This plant can scarcely be called an Alpine, but 
it resembles them in requiring special treatment. 
Plant in a well-drained, sheltered place, free from the
