The lengthening days of February will put the orchid grower again in activity, as every care must be taken and plants watched that are starting to grow. Most of the Dendrobiums will be breaking freely, and any that require more root room should not be deferred any longer, while those that have not this need should be top-dressed with live Sphagnum. In re-basketing care must be taken not to break any roots, and to give as light material as possible, say a layer of best peat at the bottom, the rest to be filled with Sphagnum, charcoal and potsherds; the plant should be fixed about two or three inches above the level of the basket. This is very important as it prevents the lodging of water about the young shoots, which are apt to rot. Water should be given sparingly at first, until the growths reach a few inches. To give them all light possible they should be suspended from the roof, but not too close, else they may get injured by frost.

AErides and most of the Vandas should be kept at rest, but never allowed to get too dry. Phakenopsis should receive a moderate supply of water. As to Cypripediums, all of the barbatum group, which includes barbatum, barbatum major, Javanicum, purpuratum and superbiens should be encouraged to growth with good supply of moisture at the roots and round the tablets; same treatment will bring to perfection Cypripedium Lawrenceanum, Cypripedium Parishii, Cypripedium Hookerae, Cypripedium Lowii and hirsutissimum. All of them will recompense the grower with a good show of their gay flowers; some of them are already flowering. Cypripedium Dominii after a short rest should, if needed, be re-potted and kept more moist, also Cypripedium longifolium and Roezlii; both of the latter are rapid growers and are better and more compact when divided every two or three years.

In the intermediate house the Cattleyas should be kept dry except Trianse and its varieties, Eldorado, Bogotensis, quadricolor, Warscewiczii and the new pet labiata var. Percivaliana; all of them are winter bloomers and require limited moisture, as well as all the winter blooming Laelias, like L. Pinelli, marginata, Dayana, autumnalis, anceps and acuminata. Odontoglossum Roezlii, O. citros-mum and vescillarium, generally grown in this house, should not suffer too much dryness.

The cool-house also deserves no less attention. Any plants of Oncidium or Odontoglossum that are pot-bound can be transferred into a larger pot without much disrooting the plant, provided the old material is sweet. Cypripedium Sedenii and Harrisonii should be kept a little dryer so as to give them slight rest; but Cypripedium Boseallii, venustum and insigne should not suffer from want of moisture. If any of the Masdevallias get sour at the roots they should be taken out and potted without delay, while those in good condition can wait till next month. As a general guide, increase the humidity of atmosphere by damping down the floor and round the pots, this will help the plants to bring out their growths.

Notwithstanding the dull and frosty weather the following plants are in flower with us:

Angraecum Eburneum

This noble orchid has six ivory white flowers on a spike; it is of easy culture, provided it gets East Indian heat, and liberal supply of water during the time of growth.

Eulophia picta, produces five or six little flowers on a spike from the base of the bulb; the color is white and rose.

Calanthe vestita and var. lutea-oculata, are among the most showy and useful orchids, especially where cut flowers are needed. The color of both is pure white with a crimson blotch in the former and yellow in the latter.

Oncidium Papilio

This, although not a new species, is one of the best of the genus. Our plant is especially a good variety. The flower is six inches across, the petals red-brown barred with yellow, sepals dark brown, lip very large red-brown with a wide yellow center and narrow edge of the same color. The spike should not be cut as flowers are produced on the same in succession.

Liparis pendula - a little plant attached to a block having spikes of about fifty white flowers, though not large yet graceful.

Cypripedium Longifolium

Our plant flowers all the year round, and though not so showy as many of the genus, yet worth growing. The flowers are of greenish color.

Cypripedium Roezlii

Not so robust as the former but more beautiful flowers. Petals and sepals rose, lip greenish yellow.

Cypripedium Purpuratum

This is a gem of the group it belongs to; a moderate grower, with straight, beautifully variegated leaves and showy flowers. The upper half of the dorsal sepal is white, the lower purplish, lip and the petals of the same color.

Cypripedium Insigne

Useful and fine species which needs no description, as anyone having a collection, however small, is not without it. There are several varieties, some better than others, but generally the whiteness in the upper sepal makes the value of a variety.

Cypripedium Venustum

This fine old species is very useful on account of its dark foliage, also being a winter bloomer. In our plant the petals instead of being greenish are purple-brown color; it is more attractive, because of the dorsal sepal being green passing in white, the lip yellowish.

Cypripedium Sedenii

Although a hybrid it has become very popular; easy of culture and rapid grower, producing its crimson flowers for five months in succession from a stem one foot high. Raised at Mr. Veitch's between Cypripedium longifolium and Schlimii and named after the raiser.

Lycaste Lanipes

It is to be regretted that this plant is so seldom met with. Stronger grower than L. Skinnerii, flowers about the same size, of fine substance and produced in quantity; the color is greenish, the lip finely fringed, mowing like elastic.

Lycaste Skinnerii

Range amongst the most useful and beautiful of orchids. Having all good qualities, easy grower, profuse bloomer, singular shaped and finely colored flowers, lasting a long time in perfection, and good for cutting on account of the long stalks. There are many varieties, the ordinary is white, rose and crimson.

Zygopetalum Mackayi

Very useful winter blooming plant of strong growth. Flowers of large size, about six on a spike, the petals and sepals are green barred with brown, lip is lilac finely veined.

Maxillaria Densa

Cluster of flesh colored flowers of small size.

Maxillaria Variabilis

A dwarf grower with dark brown , flowers.

Maxillaria Variabilis Var. Lutea

Differs only in having yellow flowers as the name indicates.

Epidendrum Floribundum

Tall growing plant with drooping racemes of small white flowers spot-1 ted with crimson.

Coelogyne Cristata

Useful plant to cut from. It is of compact habit, easy to grow, a freely flowering species. The flowers are white with yellow center on the lip. This plant should be in every collection.

Phaius Grandifolius

A fine terrestrial orchid with stout spikes of beautiful white and brown flowers. Bot. Gardens, Cambridge, Mass. \
