SEPTEMBER, 1903.] THE ORCHID REVIEW. 275 
olivaceum, Phalenopsis, andnubigenum are commencing to grow, and should, 
so soon as they have made sufficient. progress to suggest the early 
appearance of roots, be given fresh rooting material, and shortly afterwards 
a more liberal supply of water. 
The Pleiones have now about completed their growth for the season, and 
the leaves which are deciduous will soon fall aw ay. With thisin view, much 
less water should. be given, though, until the flowers appear, the compost 
should not become dust dry. There is with these practically no resting 
period, for almost before the old leaves have disappeared, the young growths, 
in which the flower scapes come up, make their appearance; hence growth 
in some shape or form is always in progress. P. humilis is only com- 
mencing to make up its growth, and should be given a fair supply of water. 
The magnificent and floriferous Dendrobium Phalznopsis is now about 
to flower on this season’s growths, and everything should be done to get these 
well developed. A fair amount of water will still be required until the 
flowers are over, when the commencement of a long and complete rest 
should begin. No shading will be required for these plants now, nor in 
fact any of the Dendrobes, except it be for an hour or so during the hottest 
part of the day in the early part of the month. With the above are 
associated the variety Statterianum and the allied D. bigibbum. The grand 
white-flowering D. formosum giganteum is also producing its blooms on the 
early-made bulbs, and should be treated like the forementioned ; those not 
in such a forward state must, however, be more plentifully supplied with 
water. D. densiflorum, thyrsiflorum, and Farmeri should, as they finish up 
‘their bulbs, be removed to a light and airy position in the Cattleya or similar 
house. 
The gorgeously coloured and much sought-for Cattleya Dowiana aurea 
‘comes into bloom this month, and where there is a good number of these 
plants a succession is kept for some few weeks. Repotting or topdressing 
may be done soon after the plants have gone out of bloom, as it is then that 
new roots emerge from the base of the last-made bulbs. Very careful 
treatment is needed after root disturbance, especially so far as watering is 
concerned, an overdose at this time often proving fatal to the plants’ 
existence. A secondary growth will often make its appearance at this 
season, or a little later on, and to hasten its development, and to insure its 
maturing before the winter sets in, plants in this condition should be given 
the most favourable position in the Warm house until these latter have 
developed. Lelia crispa, having flowered during the past month, will 
shortly commence to grow again, but very little difference in the treatment 
will be needed to that in force previously. Should any of the plants be 
forward enough to repot, it should be done as advised for other Lzlias and 
Cattleyas.
