It docs well in a house without fire-heat in the summer months, especially when in bloom : ami the Boweia 



will last the longer if kept free from damp. 



This plant is found growing in Mexico on rocks and tire*, and like most Ejtdenirum is impatient of 

 heat- The great source of failure in the management of the species of tin* genu* is the giving them too 

 high a temperature. Some years ago wo used to see fine specimens of B. nemorde and B. maencJulam 

 roseum exhibited at the Regent's Park and at Chiswiek, and now they are nearly extinct. Like many of our 

 fine Orchids they have been destroyed by the excess of heat, and by not baring secured to them proper seasons 

 of rest and of growth, without which plants cannot 1* expected to thrive. Indeed it is quite impossible for a 

 plant to be kept in perfect health without these requisitions are fulfilled- We remember some years since 

 entering an Orchid-house wherein there were from fifty to a hundred fine plants of B. macroehilum and macro- 

 chilum ro*enm growing on blocks of wood, and we never eaw them doing better, nor blooming more profusely. 

 This was a low house where there was plenty of fight, and not much .hade except while the sun was powerful. 

 The temperature was kept at from 50" to CO' in the winter, and no fire-heat was given in summer, except on 

 damp and dull days, and then only sufficient to dry up the damp. 



The manner in which Mr. Toll, gardener to J. A. Turner, Esq., has treated the plant from which our 



figure was made, b as follows s— He has kept it at the coolest end of the Mexican-house, which appears to suit 



it well, as it continues to improve ; and he has grown it on a block of wood plunged into a pot, with some 



sphagnum moss round the lower part of the plant, and with good drainage. Unlike most Orchids, it requires 



but a short season of rest. It commence* to grow after flowering in June ami July, and continues to do so 



through the winter, by which lime it shows flower. A little increase of heat at this stage will cause it to throw 



op its flowering stems much stronger. The rcaling-scason is the period after flowering. When the plant begins 



to grow, it is necessary not to give too much water, for this is apt to cause the rotting of the young shoots. The 



beTt time for potting is when growth is commencing ; mid in doing it the roots must not be bruised, for that 



would injure the bulbs, and if they arc allowed to shrivel tlicy may be a long time recovering. The best 



remedy in such a case woidd be lo place the plant on a block of wood, where it con receive a good supply of 



water to get the bulbs plump, and under this treatment it would soon make fresh roots. The plant will thrive 



well on a block of wood suspended from the roof, but then requires more moisture than when plunged in a pot. 



Propagation is effected by dividing the bulbs just before growth commences, but two or three old ones 



should always be left, behind the leading bulb. The divided ]«rtions should be placed on blocks of wood, ami 



kept moist." The plants arc not subject to become infested with insects. Sometimes the white scale will 



attack them ; if so, they must be cleaned immediately or their health will be injured.
