36 ON THE CULTURE OF THE TREE ROSE. 



the particulars respecting them shall be sent for insertion in the 

 Cabinet. 



Most of the genus is of easy culture, growing freely in pots with 

 turfy peat soil, intermixed with broken potsherds. They will 

 also grow well if tied to a piece of wood, with the bark upon it, 

 (if slightly decayed the better,) and suspended in the stove; care 

 is required to have a good deal of moisture, by watering the flues j 

 &c. where they are thus grown. The Butterfly plant does well 

 in this way, as does O. Harrisonia, flexuosum, ampliatum, diva- 

 ricatum, crispum, and bifolium. When I fasten the plant at first 

 to the wood, I attach a portion of moss thereto, and to the lower 

 part of the plant ; this aids the roots in striking sooner, and thus 

 facilitates its growth. This mode of treatment has a singular ap- 

 pearance, but the panicle of flowers has never been so vigorous 

 with me as in pot culture ; but when practised it gives a pleasing 

 variety for notice. It is well worth adopting, as all the kinds are 

 easy of increase, and amply repay by the produce of flowers. 



The general observations, at the commencement of this paper, 

 in respect to culture, are particularly observable in respect to the 

 treatment of the Oncidiums. I find that during the hot part of the 

 summer, that is, from the end of May to the end of August, the 

 plants require a slight shade. I have a Vine planted at the end of 

 my Orchideae house, purposely for the fine foliage to create a shade 

 during the period named. In procuring a shade by this means, 

 the Vine does not come close to the top of the house, but light is 

 admitted liberally there, and a few intermediate openings are al- 

 lowed, by thinning out some of the leaves in a suitable degree. 



The period of flowering, as given to each kind, is that in which 

 they have usually bloomed with me, when potted in spring j but 

 plants may be forwarded or retarded by placing them in a low or 

 high temperature, and giving them rest at different seasons.
