In a former number of the "Revue Horticole," we spoke of a plant, remarkable for the beauty of its leaves, the Begonia Hex, the culture of which is rapidly increasing, notwithstanding the recent date of its introduction into Horticulture. At present, we wish to entertain our readers with two plants, celebrated for the beauty of their leaves, and equally worthy of being sought out by amateurs. These orchideous plants belong to the genus Anoectochilus and Physurus.

On the mountains of the Moluccas and East Indies, shaded by large trees, in a moist and foggy atmosphere, is found a little plant, with leaves of an astonishingly brilliant color. The natives call it Petola. This pretty plant was brought to Europe by travellers, and has been cultivated in our greenhouses for some years. Afterwards some similar plants were found, and M. Blume established from it the genus Anoectochilus.

Although most of the orchideous plants of our greenhouses are distinguished principally for the brilliance of their flowers, those just now claiming our interest derive their beauty from the rich and brilliant color of their leaves, the flowers being insignificant.

America, and especially Brazil, has furnished us with another Orchid, which, in its downy appearance and the veining of its leaves, resembles very much the Anoectochilus; it is the Physurus of L. C. Richard. The Flora of the neighborhood of Paris has been enriched for five years with a little Orchid, the Goodyera repens, discovered in the Mall Henry IV., not far from the Castle of Fontainebleau. The Pogonias, two species of which have been very lately introduced into horticulture, belong to the same, and came originally from Java and the East Indies.

It is likely that the culture of the Anoectochilus and of the Physurus will soon be greatly increased, because already in many places these plants have been cultivated with success in portable glass cases. M. Reichenbach, the younger, the celebrated observer of Orchids, gives us a favorable proof of success in an experiment made with them in a room of Dr. Richter's, at Berlin. The situation and temperature required for our native Goodyera may be a guide in the treatment of similar plants. This grows under moss in a mixed soil, mostly made of vegetable matter; a certain amount of continual and equal moisture, and'an atmosphere charged with water, are indispensable to it.

The pot to receive the plant should be half filled with broken pieces of old pots, in order to drain it; the other half may be of a mixture of peat, charcoal, and sphagnum; the surface should be covered with moss. Finally, cover the pot with a bell-glass, which will give the plant an atmosphere charged with moisture. Morning and evening the inside of the glass should be wiped, to prevent drops from injuring the leaves, which they would gradually do. During winter they require more rest and less moisture; at this time we expose them to a temperature of 55° to 61°, and in summer 68° to 77°. They should always be carefully sheltered from the direct rays of the sun.

Ancectochilus lobhuhus, NATURAL six.

As the object is to obtain perfect leaves, the flowers should be destroyed as soon as they appear.

The Ancectochilus and Physurus are nearly allied, the difference consisting in the color of the leaves, and the countries they come from. The former, originally from the East Indies, has a more decidedly downy appearance, and the veining is usually of a golden red color. The Physurus, on the contrary, belongs to America; its leaves are of a brilliant green color, and silver veined.

The Ancectochilus Lowii of the gardens, described by Mr. Lindley under the name of Cheirostylis marmorata, and by M. C. Morren nnder that of Dossi-nia marmorata, was found in Java by Mr. Low, and introduced into Europe in 1847. It is especially pretty; the under side of the leaves is of a deep soft green color, the veining of a golden purple.

The Ancectochilus intermedium of the gardens resembles the preceding plant.

The Ancectochilus Lobbianus is known under several names - Ancectochilus xanthophyllus, Ancectochilus latomaculatus. According to some authors, the Ancectochilus Roxburghii of Lindley and the Chrysobaphus Roxburghii of Wallich are the same plant The one which we show in the plate to our readers, received its name in honor of Mr. Th. Lobb. He introduced it into Europe from Java. Its leaves are oval and pointed, their surface of a dull green, the middle of a yellowish red. The lines which trace it all over are of brilliant gold. The under side is red.

The A. 8etaceus of Blame, also called A. aureus, is originally from Oeylon.

There are still two more species, the A. argyroneurus and A, striatus.

In our horticultural establishments there are two species of the Physurus: the P. pictus of Lindley, from Brazil, with lanceolate leaves and silver nerving; and the Physurus argenteus, differing from it in having oval pointed leaves.

All the plants spoken of above require the same treatment, and it is very desirable that their culture should be extended, especially if, as is probable, these plants may be adapted to Wardian cases, which would be a graceful application of them. - Revue Horticole.
