254 GREEN-HOUSE REPOTTING. [March 



guisbeil from Sparrmdnnia by the leaves being cordate, acu- 

 minata, eid otherwise, by all its filaments being fertile, and 

 the floweis more branching, and blooming from November to 

 June, proiusely; very easily cultivated, and desirable. (Soil 

 No. 12.) 



Sphceroldbiumg) only two species of leafless plants, with 

 yellow and red leguminose flowers, which proceed from the 

 young shoots. 8. 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.) 



Sprcitgelia incarndta, the only species, a very pretty plant, 

 allied to Epdcris; foliage acuminate, embracing the stem; 

 flowers small, pink, bearded, and in close spikes; grows freely. 

 The pots must be well drained, and the plants, when dormant, 

 watered sparingly ; for if they get sodden about the roots, 

 they very seldom recover. (Soil No. 6.) 



StrelUzia, or queen plant : a genus of fine plants belonging 

 to the natural order of Musacea. S. reyina, 8. ovdta, and 

 8. humilis are the most free and beautiful flowering species, 

 and are very similar, except in habit. The flower-stalk is 

 from one to two feet long, producing about five flowers of a 

 bright yellow, having a large blue stigma, which forms a dis- 

 tinct contrast. S. jiincea and S. parviflbra are also desirable 

 species, but are more rare than the former, which ought to be 

 in every green-house. (Soil No. 19.) 



Streptocarpus rhexii, a free-blooming dwarf plant, of easy 

 culture in soil No. 4. 



StypMliaSy seven species of very showy flowers, with mu- 

 cronate leaves; corolla in long tubular form,*having several 

 bundles of hairs in it; segments reflex and bearded. S. 

 tubiflbra, crimson; 8. triflbra, crimson and green; S. adscen- 

 dens, and S. l&nyiflbra, are beautiful species. They grow 

 freely, and should be well drained, as too much water is very 

 hurtful to them. In summer, they ought not to be much ex- 

 posed to the hot sun, or the foliage will become brown. (Soil 

 No. 6.) 



Sutherland la frutescens, very similar to Swainsbnia; 

 flowers fine scarlet. (Soil No. 2.) 



8wainsbmas, four species of free-flowering, soft-wooded 

 shrubs, natives of New South Wales. 8. galegifblia, 8. 

 ^ and 8. astragalifdlia, are red, purple, and
