Next to insigne, and immediately fol- lowing it in flowering, comes C. Leea- num. The flowers of this cypripedium, while not borne on quite so stout stems as insigne, are really handsomer and worth more money, as their dorsal sepal, with its great breadth, and their attractive, showy flowers at once rivet one's attention. Cypripedium Spiceria- num X C. insigne produced this fine Market variety, and anyone wanting a companion to C. insigne should get some of C. Leeanum; it is of easy cul- ture, flowers freely and as an individ- ual plant is even better than C. insigne, unless some of its choice yellow forms are included. Both C. insigne and C. Leeanum do better in fibrous loam than in fern root. I give them a night temperature of 60 degrees in winter and provide a little shade even in the middle of winter. The great enemies of cypripediums are thrips and red spider. These soon disfigure the Leea- nums, but if a generally moist atmos- phere is kept, a high night tempera- ture guarded against and the plants sprayed on _ clear days, these pests should not trouble them when once they are located. Sponge the affected plants carefully with soap and water. Aphine has also been found to be good. Odontoglossum Crispum. The past hot summer was extremely trying on these semi-alpine orchids and the improvement many have been mak- ing for two or three years preceding was largely lost. Now, thanks to cool weather, the plants are again picking up and will, failing unforeseen contin- gencies, give a fine crop of flowers the coming spring. While the odontoglos- sums want little of our broiling sum- mer sun, they should, during our winter months, get as much of old Sol's rays as possible. It is utterly wrong to give them a dark north space, where in midwinter no sun will strike them for months. It is als
