By this time most of the potting and re-surfacing of orchids will be done, and where this is not the case, no time should be lost, and in proportion as the plants push up their growths, they should be seen to. Yet this must be done with caution, not only that one rule cannot be applied to a house, either stove or cool, but even among the many genera the different species require different treatment. For instance, in the case of den-drobes, it is not advisable to keep them at a uniform state of moisture, nor to re-pot them at the same time. As soon as the flowers fade the plants begin to grow, and this is the best time to put them in order for the growing season. Thus, the D. nobile, D. Devonianum, D. Wardianum, D. crassinode, and others come first, while the later kinds, such as D. macrophyllum, D. densiflorum, D. thrysiflorum, D. cnoschatum, and many more, should be kept at rest until they show flower spikes, when they should be put in higher temperature and held moist, to help the flowers to develop. The Cattleya crispa, C. lobata, C. ame-thystina, C. intermedia, and some of the early plants of C. Mossis, should have more moisture than the rest.
Laslia purpurata and L. superbiens should also be put in the growing quarter, and especially the former, which will soon show buds, should receive a good supply of water.
All the Odontoglossums, Oncidiums and Mas-devallias still in want of any attention in the way of re-potting or re-surfacing, should be seen to at once, before they get into active growth. The Cypripedium Sedeni, C. insigne, C. venus-tum, C. Boxallii, C. Harrisonii and C. Dominii, if needed, could be safely re-potted. The Phalae-nopsis that have done flowering, such as P. amabilis, P. grandiflora, P. Schilleriana and P. Stuartiana will resume their growths, and therefore should be put in order for the coming season. Most of the AErides and Vandas could be re-potted; this is also a safe time to lower them, considering they have some good roots left. The useful Ca-lanthe vestita and C. Veitchi will be starting to grow, and should be potted before they are much advanced, but those that are still dormant better be kept cool, in order to retard them, so as to have succession. The atmosphere should be kept moist, especially on fair days, when a good deal of ventilation is given. The green and yellow fly will make their appearance on the young growths and should be kept down by brushing them off with a soft brush. Smoking is a good remedy for this pest, but smoke is very injurious to most orchids, not only to their leaves, but the roots also.
At this time shading must be put in order, but should only be used during a lew hours when the sun's rays are strong and direct. Besides many of the plants described last month, the following are in flower. Vanda gigantea. This is the noblest in habit of its genus, if not of orchids. The leaves are about eighteen inches long and three broad, very thick, gracefully bent. It bears two spikes, the individual flowers are three inches across, of yellow, brown and crimson colors. Dendrobium chrysotoxum, a sturdy-looking plant, which produces spikes of deep yellow flowers; the lip is finely fringed. A good plant and one easy to grow. Phaius maculatus. This fine plant is worthy to be in every collection for its fine foliage alone, which is large, green spotted with yellow. Two strong spikes from one bulb bear over thirty large flowers; the color is sulphur yellow, lip nicely folded. Arpophyllum giganteum - a majestic plant, having long, arching leaves of dark green color. The flower spike is columnar, densely set with numerous rose and purple flowers. It is a beautiful and distinct looking plant. Cypri-pedium insigne, var. Maulei. This is a good deal better than the ordinary form.
The leaves are narrower, flowers of medium size, the upper half of the dorsal sepal is white, the blotches are larger and of deep purple color. Maxillaria acutipetala. The leaves are long and narrow, flowers of yellow, white and dark brown color, produced singly from the base of the bulb. Dendrobium thrysi-florum. This plant sends up a direct stem from twelve to eighteen inches high, from which are produced large pendant spikes, with twenty to thirty flowers on each. The petals and sepals are pure white, the lip yellow. A very showy plant of easy culture.
In the last number, at page 71, was printed L. Pinelli instead of L. Pinelii, O. vescillarium for O. vexillarium, C. Boseallii for C. Boxallii.
