which is placed a thin layer of sphagnum. When the stems have over- 
grown the length of the teak rods, another raft is screwed to the top of the 
old one, and at the same time, about eighteen inches to two feet of the 
plant, stem and raft is carefully sawn off at the bottom, and re-lowered into 
the pot. These bottom stems if properly taken care of may soon be 
encouraged to send out fresh growths, and in this way the plant is easily 
propagated. 
The same remarks also apply to the rarely seen Vanda Hookeriana, 
except that this variety requires warmer treatment all the year round. 
Arachnanthe Cathcartii will grow luxuriantly and bloom freely in a 
Shady part of the hottest house, where it may be syringed several times a 
day during summer. It succeeds best when trained up teak rods as 
recommended for Vanda teres. 
Arpophyllum giganteum and A. spicatum are species of Orchids that are 
generally neglected, but both plants are of easy cultivation. When seen 
with a dozen or more flower spikes twelve inches in length, which remain 
in perfection about four weeks, they lend an additional charm to the inter- 
mediate house. Both are now Starting into growth, and if necessary should 
be re-potted into a compost of good fibrous peat with one-third loam, inter- 
spersed with small broken crocks. Plenty of water when growing is 
essential, and by placing the plants in the lightest position available they 
will bloom profusely. 
Odontoglossum Krameri when well flowered is very pretty, though 
unfortunately it is often seen in a languishing condition, which is probably 
due to the roots of this plant not liking peat. I have a plant under my 
care which for some time continued to deteriorate slowly, although 
several experiments were tried to save it. At last the plant was shaken 
out, thoroughly cleansed from the old peat and moss, and re-potted into 
clean sphagnum only. The roots quickly responded to the change of 
compost, and the plant soon returned to its former healthy condition. The 
cool and shady part of the intermediate house is the proper place for it. 
Give plenty of water when in full growth, but when at rest it must be kept 
rather dryer than the majority of Odontoglossums. 
Ada aurantiaca may be re-potted, as it passes out of bloom, into equal 
Parts of peat and sphagnum. Allow plenty of drainage, so that during the 
‘Compost becoming Stagnant. In winter less will suffice, but never allow 
the soil to become thoroughly dry. This plant, with its orange-scarlet 
flowers, arranged with Odontoglossums of the crispum type, forms a very 
pleasing contrast of colour; each showing the other off to considerable 
advantage.
