March.'] GREEN-HOUSE REPOTTING. 253 



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 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. dentdta, with 

 rosy leguminose blossoms; leaves opposite, ovate, acuminate, 

 serrate ; S. anyustifdlia, has brown flowers ; S. trapezifbr- 

 mus, 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 th; world. They are even found near the limits of 

 perpetual snow, where neither tree nor shrub is able to rear its 

 head, and yet there are a few species that are neat little 

 plants, and are worthy of a situation, namely, *S'. grandlflb- 

 rus, iS. venustus, and S. cinerdscens, with the double white, 

 purple, and red variety of $. elegans. The last three varie- 

 ties are free flowering, but if allowed to grow several years, 

 they become unsightly. Being very easily propagated, a few 

 cuttings of them should be put in in September, and in two 

 weeks they will strike root, when they may be put in pots to 

 keep through the winter, and then planted in the garden, con- 

 tinuing to renew them. The other mentioned species should 

 be frecpuently done the same way. Do not keep them damp 

 during winter, or they will rot off". Give them an airy expo- 

 sure. (Soil No. 12.) 



Sdllya heterophylla : a good climbing plant, with bright 

 blue clusters of drooping flowers; it is a native of New Hol- 

 land, and will prove a hardy plant south of latitude 36 

 (Soil No. 4.) 



Sparrmdnnias are strong-growing green-house shrubs. S. 

 Afiicdna is a plant very common in our collections, with 

 large three-lobed cordate leaves, hairs on both sides; flowers 

 from March to July. S. rugdsa. The leaves are rugged; 

 flowers of both are white, in a kind of corymb, supported by 

 a long footstalk ; buds drooping, flowers erect. There is a 

 plant known in our collections as the free flowering Sparr- 

 mdnnia (which is Entclia arborescens), and is easily distin-
