Juncus
(from jungo, to join; the leaves and stems of this genus having been employed as cordage). Rush. ORD. Junceae. A genus of about a hundred species of hardy, annual or perennial herbs, usually with a rigid habit, principally natives of Arctic and temperate regions. Flowers greenish or brownish, small, disposed in heads or panicles. Very few species of this genus are worth cultivating. The perennials thrive in almost any boggy situation, and may easily be increased by divisions of the root.
J. effusus spiralis (wide-spread spiral). A curious and desirable variety, forming spreading tufts of stems, which, instead of growing straight, like those of other kinds, are curiously twisted in a regular corkscrew form. From its very unusual appearance, it is well worthy of cultivation, and may be planted with advantage on the margins of pieces of water, near cascades, &c., or in an artificial bog.
J. laetevirens (bright-green).* l. bright green, in crowded tufts, somewhat distichously sheathing at the base, and distinctly compressed at the sides. h. 3ft. Japan, 1880. A free-growing and exceedingly ornamental hardy plant. This is probably not a Juncus at all.
J. zebrinus. See Scirpus Tabernaemontani zebrinus.
