,] GREEN-HOUSE-REPOTTING. 



Roellas, pretty leafy shrubs, with blue terminale fun- 

 nel-shaped flowers, lip-spreading ; R. cilliata, R. spi- 

 cata, and R. pedunculate are the finest of the genus. 

 The pots must be well drained, and care taken that 

 they are not over-watered. 



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. 

 elegans, S. splendens, S. ccerulea, and S. coccmea, (which 

 in artificial climates constitute the standard of the 

 genus,) are not worth cultivation. These last men- 

 tioned, if kept in the Green-house, will merely keep in 

 life, but a situation in the Hot-house would cause 

 them to flower frequently. 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 pre- 

 served during winter in pots. They neither grow nor 

 flower so well as when planted out, and even a slip plant- 

 ed 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. S. aurea, S. panicu- 

 lata, and S. indica, are fine species. The latter is white 

 and blue, with large leaves ; flowers monopetalous, and 

 irregular ; colour generally red or blue in spiked whorls. 

 All will grow easily with encouragement. 



Senectos. Some species of this genus are pestiferous 

 weeds all over the world. They are found near the 

 limits of perpetual snow, where neither tree nor shrub
