The species are all slender, hardy, green-house plants, of pretty appearance, and easy cultivation. 250. Opercularia. From operculum, a lid, in allusion to the manner in which the calyx is closed. Plants of no beauty. 251. Cryptospermum. From κρύπτω, to conceal, and σπερμa, seed. The seeds, or rather seed-vessels, are hidden in the involucrum. Weeds of some tropical countries. 252. Pothos. From potha, the native name of this plant in Ceylon. Most of the species are sub-parasitic, and found climbing, like ivy, on the trunks of trees in the West Indies and America. In our stoves most of the species will thrive planted in old bark and moss, and plunged in heat. P. palmata has leaves upwards of three feet long, with a foot-stalk nearly four feet long, palmate, as thick as strong parchment, smooth, with a midrib of a deep green above, and the fructification on spikes more than a foot in length. The species are cultivated for the sake of their foliage, which is always of an agreeable green color, and not liable to discoloration by damp or other accidents of a hot-house. 253. Rivina. In memory of A. Q. Rivinus, a native of Saxony, born in 1652, and died in 1722. He was for a long time professor of botany and medicine at Leipsig, and left behind him some valuable botanical works; and among them a very ingenious attempt at a classification of plants by the corolla; from which some modern botanists have profited more than they have acknowledged. The name, as Linnæus observes, with his usual neatness, has been given to a shrub always covered with leaves and fruits, in allusion to the merit of the works of Rivinus. R. octandra, the Hoop-withy of Jamaica, and liane à baril of Martinique, has a very long tough flexile stalk an inch or more in diameter, and sometimes made into hoops in the West Indies.

Camphorosma. Barbarously named from two words, the one Latin (camphora), and the other Greek (oσμη), signifying a smell of camphor. The plant abounds with a volatile oily salt, and is warm and stimulating; but its appearance has nothing to recommend it . 255. Alchemilla. Named, as Linnæus asserts, from its supposed alchymical purposes; but, as others maintain, from its Arabic app appellation alkêmelyeh. (J. de Souza, p. 52.) A. vulgaris is eaten readily by horses, sheep , and goats, and is considered a good herbage-plant where it abounds in upland pastures. A. alpina is an elegant species, common on many of the Highland mountains, and supposed by Lightfoot and others to aid considerably in giving the peculiarly excellent flavor to Highland mutton. A. aphanes is a worthless weed. 256. Sanguisorba. From sanguis, blood, and sorbere, to absorb. The plant has passed for an excellent vulne- This genus greatly resembles Poterium (Monoecia Polyan.), and Professor Martyn observes, that it is certainly a defect in the Linnæan system that two genera so similar in habit should be placed so far apart. A profound remark, and quite worthy the professor of botany of Cambridge. Alas! poor Linnæus ! if he could rise from his grave he would have little cause to congratulate himself upon the aid of those who call themselves his champions, and the expounders of his system. 257. Dorstenia. In memory of Theodore Dorsten, a German, author of a work entitled Botanicon, printed in 1740. Its flowers, says Linnæus, are like the works of Dorsten, they have little to recommend them. The roots are imported under the name of Contrayerva roots, and used both in medicine and dying. OLEASTER. narrow-leaved silvery oriental 256. ISNARDA. W. 1529 palústris W. 259. ELÆAG NUS.
