260 GREEN-HOUSE REPOTTING. [March. 



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. grandiflorus, S. venustus, and S. dnerdscens, with 

 the double white, purple, and red variety of S. elegans. 

 The last three varieties 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, continuing to renew them. 

 The other mentioned species should be frequently done 

 the same way. Do not keep them damp during winter, 

 or they will rot off. Give them an airy exposure. (Soil 

 No. 12.) 



Sollya helerophylla : a good climbing plant with bright 

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

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

 (Soil No. 4.) 



Sparrmdnnias are strong-growing green-house shrubs. 

 S. africdna is a plant very common in our collections, 

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

 flowers from March to July. S. rugosa. 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 Sparrmdnnia, (which is Entelia arbores- 

 cens,) and is easily distinguished from Sparrmdnnia by 

 the leaves being cordate, acuminate, and otherwise, by all 

 its filaments being fertile, and the flowers more branching, 

 and blooming from November to June, profusely; very 

 easily cultivated, and desirable. (Soil No. 12.) 



Sphserolobiums, only two species of leafless plants, with 

 yellow and red leguminose flowers, which proceed from 

 the young shoots. S. vimineum and S. medium. They 

 flower freely, and are easily cultivated. The old wood 

 should be frequently cut out where it is practicable. 

 Drain the pots. (Soil No. 6.) 



Sprengelia incarnata, the only species, a very pretty 

 plant, allied to JEpdcris ; foliage acuminate, embracing the 

 stem; flowers small pink, bearded,^ and in close spikes; 

 grows freely. The pots must be well drained, and the
