March.~\ GREEN-HOUSE REPOTTING. 259 



are several other species lately brought from that country, 

 which are highly valued : the species are R. campanula- 

 turn, R. anthopogon and R. cinnamomum. They are 

 rarely seen in our collections, but a few years will make 

 them more plentiful. Their beauty of flower is beyond 

 description. 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 growing, give 

 copious waterings at the root. For young plants soil No. 

 6. And for blooming plants use one portion of leaf 

 mould. 



Roellas, pretty leafy shrubs, with blue terminal funnel- 

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

 R. pedunculata, 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, 

 shrubby, 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, crim- 

 son, S. splendens, scarlet, A', angustifolia, ^>ale 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 flower abundantly, and in 

 the fall they can be lifted, and preserved during winter in 

 pots. They neither grow nor flower so well as when 

 planted out, and even a slip planted in the ground in moist 

 weather will root in a few days, grow, and flower in a few 

 weeks. S. splendens is the best to select for the purpose. 

 All will grow easily with encouragement. (Soil No. 12.) 



Scottias, three species of valuable plants ; S. dentata, 

 with rosy leguminose blossoms; leaves opposite, ovate, 

 acuminate, serrate ; S. angustifolia has brown flowers ; 

 S. trapeziformus, leaves ovate, acute, serrulate. We do 

 not know the colour of its flowers ; the pots must be well 

 drained, and the plants kept in the warmest part of the 

 green-house, and near the light. (Soil No. 6.) 



Senecios. Some species of this genus are pestiferous 

 weeds all over the world. They are even found near the
