Now that we have so many beautiful summer-flowering exotica for the decoration of conservatories and greenhouses, there is no excuse for turning these structures into lumber rooms during summer; for, although it is a season when flowers are abundant in the open air, there are many fine exotics that are too delicate to flourish unless protected ' Of these the Archimenes are conspicuous, and afford sufficient variety in themselves to satisfy the most fastidious in floriculture. They are well adapted for those who wish to make the most of a greenhouse, growing rapidly in summer, requiring no care, and taking up no valuable space during winter. They are also easily propagated, and were it necessary so to increase them, almost every scale of the tuberous roots will make a plant. The tubers, however, increase sufficiently for ordinary purposes, and if allowed to remain entire produce stronger plants. The routine treatment they require is very simple; where the convenience of a hothouse can be secured they may be had to bloom in June, but they will succeed well, although somewhat late in blooming, even if brought forward in a frame, or in the greenhouse.

Very fine plants are produced by placing single tubers in small pots, growing them in a warm house, and shifting into larger pots as they require, stopping or pinching the branches, and thus inducing a spreading, stocky plant; but an equally successful mode is to deposit six or eight of the tubers in a pot, allowing them to grow into a large cluster. This method is especially adapted for such sorts as Longiflora, Longiflora alba, Coccinnea, Rosea, and those of similar growth. Stronger growing kinds, of which Grandiflora and Pedunculata may be taken as examples, should not be planted so thickly; three plants in an eight-inch pot will be sufficient for these, and by stopping the points a very large mass may be obtained, although the stopping of the points will render them later in flowering.

The soil for them should be of a light and porous nature. The fibrous portions of rotted sod, mixed with leaf-mould and sand, will be very suitable; charcoal dust is a good material for mixing with the soil if destitute of fibre; as they require liberal watering at certain seasons, a free transmitting soil and thorough drainage must be provided.

In their young state they should not be kept very wet, but as they come into flower, plenty of water will be necessary, and a shaded, moist atmosphere will be inducive to their rapid growth; shading from sun will extend their flowering very materially.

When the flowers fade and the foliage shows symptoms of maturity, let the watering be gradually abridged; the tubers will ripen more perfectly if the plants are placed out in the open air under a glass cover, however, to protect from rains, and they will keep well by laying the pots on their sides under the staging in the greenhouse. This simple treatment ensures me a great display of flowers, and keeps the greenhouse a "thing of beauty V all the summer.
