and Sons, in 1882, through their collector, Curtis, who found it at some 
distance from Pahang, at an elevation of 3,000 to 4,000 feet, on the great 
mountain range which extends almost throughout the length of the island. 
It was shortly afterwards described by Reichenbach, under the name of 
Cypripedium Curtisii (Gard. Chron., 1883, ii. p. 8), and figured in the 
Orchid Album (ili. p. t. 122). The species is allied to P. ciliolare and P. 
superbiens. 
CALENDAR OF OPERATIONS FOR SEPTEMBER. 
By W. C. PRIcE, OAKDENE, WEsT DIDsBURY. 
GENERAL REMARKS.—AI] secondary shading that has been employed 
during the summer should be removed by the middle of the month. The 
down spouts leading into the tanks should be firmly stopped up before 
commencing, and the houses thoroughly washed down outside. The 
spouting should also be well cleaned out after washing down, leaving the 
plug in until this is done, so that no sediment gets into the tank. The 
inside of the houses should be washed down as soon afterwards as possible, 
and all pots and staging thoroughly cleaned. When re-staging, the plants 
should be placed in their winter quarters, and got well up to the glass, but 
not too close, as they would suffer more if by any means a fall in the 
temperature occurred during the winter. All bare walls should be well 
scrubbed, and lime-washed with new lime, especially under the stages, as it 
helps to keep the slugs and other insect pests from crawling up, also to keep 
the houses sweet. 
SLUGS AND COCKROACHES, now that the cold nights are coming on, 
will make their presence felt, and destroy a lot of flowers and spikes unless 
kept down. Slugs may easily be trapped if lettuce leaves or bran is laid 
down in places and examined night and morning. Cockroaches may be 
cleared by putting down at frequent intervals, on pieces of glass, a small 
portion of arsenic and honey mixture. The proportions should be two 
ounces of arsenic to half a pound of honey, and any chemist will mix it for 
you if you state the purpose for which it is required. 
SHADING.—Now that the days are shortening and the sun waning in 
power, the blinds can be left up later in the morning, and pulled up earlier 
in the afternoon. Make the utmost possible use of the sun to ripen things 
up without overdoing it. All plants that have finished their growths should 
_be placed together in their respective houses, where they can be treated 
accordingly, so that they are not tempted to make a second growth. Keep 
the fires well in hand, so that they can be used at once if wanted, as a 
sudden check now would do a lot of harm. 
_. Dampinc.—This operation will not be required so frequently now, 
though the houses should not be neglected. Keep a nice buoyant
