Bot (Mag History Use Propagation) (VII)

mag. 1457 6804 6800 6805 6808 6803 History, Use, Propagation, Culture, 6809 Many of the stove species of this genus are succulents, and will thrive the better if a little lime rubbish be added to their sandy loam. They are somewhat difficult to strike. Sweet says, "The way I have succeeded best, is to stick them in the tan amongst the pots in a good heat, and not cover them with any glass." (Bot.. Cult. 55.) The inflorescence of this genus is not now considered to consist of twelve stamens surrounding an ovary; but almost as in Reseda, of a number of monandrous naked male florets surrounding a naked female floret. This manner of understanding Euphorbia was first indicated by Jussieu, and afterwards correctly explained by Mr. Brown. 1104. Pedilanthus. From πεδiλov, a slipper, and avθoς, a flower, in allusion to the form of the involucre. A genus resembling Euphorbia in properties and appearance. 1105. Visnea. This seems to be a blunder of the younger Linnæus for Vismea, which now is the name of a distinct genus, which see. Ripened cuttings root freely in sand. ORDER III.

Calligonum. From κaλoς, beautiful, and you, a knee or joint. This plant produces, instead of leaves, curious greenish excrescences disposed in joints, which give it a remarkable appearance. 1107.
