A very curious little plant, only an inch or two in height, found in Trinidad growing upon rotten sticks in the woods. It bears two or three green flowers, which contain a column, the upper extremity of which is lengthened out into a fine subulate process, resembling a snipe's bill in miniature, whence the name, from oρviθiς, a bird, and κεφaλη, a head. No successful method of cultivating this plant has yet been discovered. 1911. Bletia. Dedicated to Luis Blet, a Spanish apothecary, who has always, as we are informed by the authors of the Flora Peruviana, distinguished himself in his botanical studies. Very noble plants, growing in the earth.

Bletia Tankervilliæ is a common but beautiful species. The first plant which flowered in this country, was cultivated at Apperly Bridge, near Bradford, in Yorkshire, in May 1776, and had been sent there to Mrs. Hird, by her uncle, Dr. Fothergill, in a black Chinese pot full of stiff loam, in which it had been imported. Many small bulbs, with leaves like those of a snow drop, grew near the edge of the same pot in a regular circle, and these afterwards proved to be Amaryllis Aurea. The Bletia Tankervilliæ delights in warmth, fresh loam, and plenty of water, by which treatment, and attention to fecundate the stigma, it will ripen fruit abundantly. 1912. Eria. From ερiov, wool, on account of the woolliness of the flower of all the known species. Curious epiphytous plants, with bulbous roots, and flowers usually of a yellowish color. They differ from Dendrobium chiefly in the number of their pollen-masses, and in habit. E. stellata is a fine free-growing plant, with long broad fleshy leaves, and spikes of beautiful brown-yellow flowers nearly a foot and half in length. 1913. Octomeria. So called by Mr. Brown, with reference to the eight parts, όκτo, and μερoς, into which the pollen is divided. A singular little plant, with filiform leaves and small nearly solitary flowers. The true limits between this genus and the last remain to be determined. The two seem to be separated by nature. 1914. Brasavola. Named after Antonio Musa Brasavola, an Italian botanist, born at Ferrara in 1500. Plants with long subulate fleshy leaves, and large white flowers. They are cultivated without difficulty in peat and sand, if good decomposed wood is not to be procured. 1915. Sarcanthus. A curious genus of plants not remarkable for their beauty. Their habit is various, but always caulescent; their flowers either yellow or yellowish, marked with various shades of purple. The name ORDER I.

Vanda. The Hindoo name of the original species. Noble caulescent plants adhering to old decayed arms of trees or fallen wood, by means of their tendril-like fleshy tortuous roots. The flowers of all the species are large and shewy. Their treatment is the same as the next. 1917. Aerides. Derived from aër, the air; in allusion to the peculiar property the species possess of existing many months suspended in that element. This genus and the two last are those to which the name of Air-plant is most properly applied, very few others being capable of enduring for any considerable period such a removal from their natural places of growth. The true species of this genus are beyond all comparison the most delightful productions of the vegetable world. Their flowers are arrayed in long spikes or racemes of delicate colors and delicious fragrance. Hung up in a room in their native country, a little before flowering, they continue to unfold their blossoms in gradual succession for many weeks. In this country they are rarely seen in flower. The only genuine species, the A. odoratum, should be planted in rotten wood with a little peat, or a few decayed leaves, or any light black vegetable mould, and kept in the hottest and dampest place of the stove.

If put in baskets among moss and kept very damp, the plants will succeed for a short time, but they soon languish, and put on a yellow appearance, the certain indication of unhealthiness. e 1918. Renanthera. A name contrived by Loureiro, to express the kidney-form or reniform shape of the pollen-masses. This plant is not uncommon in good collections, where it has sometimes acquired the height of six or eight feet; ; but it has never yet produced its flowers. These appear, in the native country of the plant, in large loose panicles, and are individually of considerable size and of a rich crimson color, a little mottled with yellow. 1919. Ionopsis. So called by Mr. Kunth, from sov, a violet, and oψiς, resemblance. I. utricularioides is a pretty little epiphyte, with purplish falcate leaves. It succeeds ill under any management which has hitherto been applied to it. 1920. Eulophia. From εuλoφoς, well crested, with reference to the surface of the middle lobe of the lip. The two species in the gardens are terrestrial tender stove plants, with bulbous roots, plaited leaves, and flowers, in species in the gardens are terrestrial tender stove plants, with bulbous roots, plaited leaves, and flowers, in E. exaltata, green and inconspicuous, in E. guineensis, whitish pink, and very handsome. They should be treated like Cymbidium.
