SS52 GREEN-HOUSE REPOTTING [March 



seed that they will soon be so much amalgamated that the 

 named sorts will not be distinguished. A green-house with- 

 out some of the choice varieties of this plant is deficient of a 

 flower whose beauty and grandeur are beyond the highest 

 imagination. It is a native of Nepaul, in India, and when 

 found by Dr. Wallach, awakened the ambition of every culti- 

 vator and connoisseur in Europe.* There are several other 

 species lately brought from that country, which are highly 

 valued : the species are R. campanulatum, R. antlwpogon, 

 and R. cinnamomum. They are rarely seen in our collections. 

 There is also another new addition to this already majestio 

 family, discovered by Doctor Hooker, in the Himalaya Moun- 

 tains, which for gorgeous splendour is supposed will surpass 

 all their predecessors; the foliage of many of them are cer- 

 tainly distinct and unique in all its parts. We have also a 

 brilliant yellow species, R. javanicum, from Japan ; it is 

 novel and beautiful, blooming when the plants are only about 

 a foot high an indispensable sort. The pots should be well 

 drained, and if they are large, put several pieces of sandy 

 stone or potshreds around the side, for the fine fibres delight 

 to twine about such, being mountainous plants. When grow- 

 ing, give copious waterings at the root. For young plants, 

 soil No. 6. And for blooming plants use one portion of leaf 

 mould. 



RoellaSj pretty leafy shrubs, with blue terminal funnel- 

 shaped flowers, lip-spreading; R. ciliata, R. spicata, and R. 

 pedunculdta are the finest of the genus. The pots must be 

 well drained, and care taken that they are not over-watered. 

 (Soil No. 6.) 



Sdlvia (Sage) is an extensive genus of soft-wooded, shrub 

 by, or herbaceous plants ; very few of them do well in the 

 green-house, and many of them are very trifling, having no 

 other attraction than the flower ; and those of the tender 

 species, when compared with S. fulgens, crimson, S. splen- 

 dens, scarlet, S. angusttfolia, pale blue, S. patens, dark blue, 

 S. involucrata, pink (which in artificial climates constitute 

 the standard of the genus), are not worth cultivation. The 

 best method to adopt with the summer flowering kinds is to 

 plant them in the garden in May : they will grow strong and

 first plant of arboreum from seed in England.
