SEPTEMBER, 1911.] THE ORCHID REVIEW. 283 
back bulbs, leave only three to support the new growth. Weak plants 
should be potted very lightly, but those which are strong growing and well 
rooted, more firmly, using less crocks. 
After the potting operations have been finished the work of thoroughly 
cleaning the house should be taken in hand. Remove all plants from the 
staging, thoroughly wash this, and syringe all corners and crevices with a. 
strong solution of insecticide. The glass and woodwork should then receive 
attention, and finally the pots should be scrubbed and the plants rearranged. 
Place those freshly potted at the warmest end, and those resting at the 
coolest end. Any necessary top-dressing should be done now. 
Oncidium tigrinum, O. varicosum, and its superior variety Rogersié 
should now be showing spikes, and these should be tied to neat sticks, and 
a piece of cotton wool wound round the base of the spike as a preventative 
against slugs. 
CATTLEYA House. 
No shading should now be used here, as plenty of sunlight is necessary 
to thoroughly develop the new pseudobulbs. Any plants which are im 
flower should be removed to a cooler house, or shaded with tissue paper- 
Give water and syringe as advised in the last article. The above method of 
procedure should be adopted in the overhauling of this house. 
Should any Vanda ccerulea be in spike, these should be kept slightly 
shaded, and just moist. Stanhopeas may now be rebasketed, using a com- 
post of osmunda, sphagnum and peat. Be careful to put no crocks in the 
new receptacle for the flowers are produced from beneath the basket. Keep. 
all resting plants only just damp. 
SUGGESTED ADDITIONs. 
CYMBIDIUM INSIGNE.—This beautiful species is of recent introduction, 
and extremely showy. It succeeds well in the Cool house, and should be in- 
cluded in every amateur’s collection. It is a very robust grower, and free in 
flowering when given exactly the treatment which it requires. The flowers 
are of large size, and firm and fleshy in texture. The sepals and petals are 
of a pale blush pink, the lip almost white with many spots and markings of 
a deep carmine. It is entirely different from any which have yet appeared 
as regards colour, and the blossoms are produced in March and April, and 
are borne in long racemes. 
CATTLEYA DOWIANA AUREA.—This is one of the most beautiful of alk 
Cattleyas. It produces from a sheath at the apex of the last-made pseudo- 
bulb large finely-shaped flowers, the sepals and petals of which are of a 
-golden yellow. The lip is broad, handsomely crisped at the edges, of a 
deep crimson, with radiating lines of gold. It usually blooms in the months 
of August and September, and continues about three weeks in beauty. It 
is a native of Antioquia, and owing to many large importations of recent
