Streptantnera 



( 370 ) 



Streptosolen 



are obtained by planting out in a sunny position 

 in a well-drained border. A minimum temperature 

 of 50 should be given.

STREPTANTHERA. 



Dwarf, bulbous plants (ord. Iridese), suitable for 

 a sunny greenhouse. Propagation, by offsets. 

 Soil, sandy loam. A decided rest, with no water 

 after the leaves have died, is necessary.

STREPTANTHUS. 



Hardy annual, or perennial herbs (ord. Cruci- 

 ?<;rse), usually with purple, sometimes with white 

 or yellow, flowers. Propagation, by seeds, sown in 

 April, where the plants are to bloom, for the 

 annuals ; and seeds and root division for the 

 perennials. The two species named below, which 

 are probably the only ones in cultivation, are both 

 annuals.

STREPTOCALYX. 



Stove evergreens (ord. Bromeliaceae), allied to 

 and requiring the same treatment as jEchmea and 

 Bromelia. A few species only ave known, and 

 those are very rarely seen. 



Principal Species : 



Fuerstenbergii, !'_' , Oct., Vallerandi, 2 . aut., vio.,

STREPTOCARPUS. 



Description. This genus (ord. Gesneracese) of 

 greenhouse and stove herbaceous perennials has 

 become of importance during the past few years. 

 Prior to the advent of the hybrids the plants were 

 not largely grown, but the work of improvement 

 commenced at Kew has been very successful, and 

 the Streptocarpus is now a genus of many splendid 

 forms. 



Propagation. By seeds sown in gentle warmth 

 in spring, and subsequently pricked off and potted 

 as becomes necessary. The young plants should 

 be grown as sturdily as possible. Increase may 

 also be done by division, but better plants are 

 obtained from leaf cuttings. 



Soil. Medium, mellow loam, with a little leaf 

 mould and coarse sand. 



Other Cultural Points. In the young state 

 particularly the utmost care must be taken that 

 the soil does not become dry, and that cold 

 draughts do not reach the plants. Either of these 

 errors will inevitably lead to failure. In the early 

 stages gentle heat is desirable. The plants will 

 flower profusely the second season, and are then 

 useful for greenhouse and conservatory decoration, 



where the cooler, drier temperature conduces to 

 prolonged floriferousness.

 division in spring. Any good garden soil.

STREPTOSOLEN. 



Description. An evergreen greenhouse shrubby 

 plant (ord. SolanaceEe). The deep orange coloured 

 flowers are freely produced in terminal heads 

 For a warm conservatory it is a fine subject, flower- 

 ing over a long period, but most profusely in spring 

 and summer. 



Propagation. By cuttings, in sandy soil, in a 

 warm pit, under a bell-glass. 



Soil. Light loam and leaf soil in equal i>arts, 

 with a little dried cow manure and plenty of 

 coarse sand.
