DESIRABLE DECORATIVE PLANTS. 

 Franciscea. This is a very beautiful 

 genus of the order Selanaceae. All 

 its species are highly decorative, de- 

 liriously sweet, and can easily be 

 brought into bloom at any season of 

 the year. They are invaluable objects 

 both for the conservatory and exhibi- 

 tion purposes. They are not grown 

 these days as extensively as they had 

 been, one rarely finds them even on 

 private places, which is a thing to be 

 regretted. 



They are all evergreen shrubs, easily 

 propagated by cuttings in sand in 

 gentle bottom heat, with a bell-glass 

 over them. To grow them success- 

 fully, they should be potted in a mix- 

 ture of loam and leafmould with a 

 liberal quantity of sand. After they 

 have done flowering they should be 

 directly shifted and placed in a tem- 

 perature of 60°-65°, keeping them well 

 watered and syringed. When the 

 young shoots have made four or five 

 leaves, the tops should be pinched off, 

 continuing it until October, usually 

 the time when the flowers commence 

 to appear and when syringing must be 

 reduced. If the plants are not wanted 

 in bloom at this time they should be 

 placed in a cold house at a tempera- 

 ture of 45°, and brought forward as 

 desired. The most desirable species 

 are calycina, calycina major, exima 

 and latifolia. 



Centradenia grandifolia. A very 

 pretty and freeflowering plant, belong- 

 ing to the order of Melastomaceae and 

 is a native of Mexico. It has large 

 oblong-ovate leaves, intensely green 

 above and deep red beneath, the stem 

 is quadrangular, and the flowers 

 white, tinged with pink. It blooms 

 throughout winter and spring without 

 cessation, always producing such an 

 abundance of bloom that the plants 

 become very effective and useful. It 

 is as useful and decorative for the or- 

 dinary house dwelling as for the con- 

 servatory. They are of very easy cul- 

 ture, readily propagated by cuttings 

 in gentle bottom heat, 



Coronilla glauca. This is a useful 

 decorative shrub belonging to the 

 natural order of Legumiuoceae, and is 

 a native of France and Sicily. Its 

 leaves are compound, leaflets obovate 

 and of glaucous green color: flowers in 

 umbels of seven or eight, of bright 

 yellow color and very fragrant. It is 

 an invaluable plant for the winter and 

 siuing decoration, well meriting a 

 more prominent place in the florkul- 

 tural world. It is readily propagated 

 by cuttings of the young wood and 

 requires the same cultural treatment 

 as the Genista, which it resembles 

 much in growth and in flower.
