History, Use, Propagation^ Culture, 
sparrow or other small bird. 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. Cryptospermurn. From x^vrTu, to conceal, and a-'zi^fx.ci, 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 bo- 
tanists have profited more than they have acknowledged. The name, as Linnaeus 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 d 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. The^berries con-
