greenhouse 9 months in the year ; and many doing well in the open 

 air, if in a somewhat shaded situation. They are for the most part 

 natives of Brazil or Mexico. 



To cultivate them successfully we must divide them into two 

 classes: — the tuberous rooted, .and the shrmhby* Each of these will 

 require separate treatment. The following kinds are amongst the 

 best in cultivation, either here, or in English gardens, from whence 

 they can be easily procured. 



Tuberous Rooted. 



1. B. discolor or Evansiana, native of China, with pinkish white 

 flowers, maybe had in bloom from May to October. 



2. cinnabarina, from Bolivia, deep pink or cinnabar, from June 

 to October. 



3. Martiana, from Brazil, deep pinky rose, from July to October. 



4. diptera, Cape of Good Hope, whitish, June to August. 



5. Barkeri, Mexico, dull white, February to December. 



These require to be kept rather dry and cool in the winter sea- 

 son. No. 5. maybe bad in flower ail the year, by having several 

 pots, and keeping them dry at different periods. Early in spring 

 the tubers may be potted in 6 in. pots, in a soil composed of well- 

 decayed leaf mould, loam, and gaud. They require little water 

 till the leaves appear, when they will take an abundance. They 

 may be forwarded in a little heat, but will do pretty well if allow- 

 ed to come along with the season. They are easily propagated 

 from their tubers, by cuttings, or by seeds. 



Shrubby or Fibrous Rooted. 



1. B. nitida, native of Jamaica, with pinkish white flowers, and 

 large, thick, shining leaves. May be had in bloom all the year, and 

 made into handsome specimens. 



2. B. spathulata, another West Indian,' with a very erect habit 

 of growth. The leaves are folded in like spoons, and the small 

 white flowers appear at the ends of the young growth. It flowers 

 from August to December, and is but an average kind. 



3. B. odorata, a Brazilian kind allied to the last, but has a fine 

 foliage, resembling nitida, the flowers came out like the last from 

 August to December, are much larger and sweet scented.
