I write for information concerning my failure to produce good blooms on Cypripedium insigne. Two years is the limit of my experience with them. I keep them in a temperature of 55 to 60 degrees. They are good-sized plants in 7-inch pots. The foliage is a dark green, healthy color. They throw out the budsj but when they get to a cer- tain stage—say when the stems are three or four inches long—the stems get limp or soft and the buds turn brown or blight and die. I have been able to carty along a few plants with blooms, but these are inferior. A friend sug- gested that the atmosphere might be at fault, but I ventilate freely. The plants are within two feet of the glass and right under the ventilation. It was also suggested that too much moisture, from giving them more water than is necessary, might be the cause. Any in- formation on this subject would be greatly appreciated, as I have had this trouble two years in succession. The plants are potted in half peat fiber and half rotted sod. I have not fed them with any fertilizer. C. D. H. Your temperature seems to be all right, and if the plants are within two feet of the glass they are in an ideal location. Cypripediums like a fienial, moist atmosphere, while some other orchids, such as cattleyas, need a drier and airier one. The plants should not stand where they will get any direct current of air from the ven- tilators. I think the most likely cause of the spikes going off is too much water at the roots. Though cypripe- diums are terrestrial orchids and never have a resting period, yet they are more injured by an oversupply of water than the reverse. If you water
