BULBOPHYLLUMS AND CIRRHOPETALUMS —Among these are p h ps some 
of the most peculiar, extraordinary, and most weird of all flowers, and it is 
very pleasing to note how eagerly they are being sought after by our present- 
_ day Orchidists. In addition to their wonderful construction, some can ~ 
claim attention by reason of their beauty, if not of shape certainly in the. 
wonderful colouring. To grow a nice collection would not take up much. 
space, and at any rate a few should be given a place in all collections, 
where a warm house is available. 
In most cases their growth is somewhat slow, yet they must not be 
classed among the difficult Orchids, providing they are not coddled too 
much. Such plants want close attention to details, but what plants do 
not? Their season of growth is practically all the year round, but a 
beneficial rest may be given them by keeping them rather dryer after their 
growth is completed till they start away again. At the present time 
Bulbophyllum virescens, B. Ericssoni, B. grandiflorum, B. Dearei (Godseff- 
ianum), and B. Lobbii are all growing freely in the stove Orchid house. 
Though during the brighter portions of the year these are all shade-loving 
plants, at this season they will be helped considerably by being placed in a 
light position. 
Cirrhopetalum appendiculatum, C. Meduse, C. Cumingii, C. refractum, 
C. retusiusculum, and Bulbophyllum Dayanum are grown in a corner in the 
Cattleya house. The three first-named are now active, and although they 
do not need copious supplies of water at this season, they should not be 
allowed to remain dry for any length of time. The others have their new 
bulbs developed, and may to advantage be kept on the dry side, but in the 
cultivation of these the resting time must be given when they are ready for 
it, irrespective of season. 
The most suitable time for potting is when new roots are being emitted. 
The time of year does not make much difference. I have found a mixture 
of very fibrous peat and sphagnum in equal parts, very suitable. ‘Being in 
Most cases surface-rooting plants, there is nothing gained by giving much 
depth of material, and it will be found far better to fill the receptacle half 
full with drainage. When such varieties as B. virescens or Ericssonii are 
being done, the back part should be kept right on the side or end of the 
receptacle, so that the lead will have ample room to develop, and root on 
to the material forward. 
They are easy subjects to propagate. I have found the best results 
accrue from cutting away the leads with one or two bulbs attached, and 
thus leave the old plant undisturbed till it has made new leads. 
CHONDRORHYNCHA CHESTERTONI.—This beautiful species has in the 
Past been classed with the troublesome sections of Orchids, and it was only 
very rarely that a healthy plant was seen. No doubt the trouble in the past
