It is well represented in See also:Britain by the two genera which comprise nearly the whole order—Juncus, rush, and Luzula, See also:wood-rush. They are generally perennial herbs with a creeping under-ground See also:stem and erect, unbranched, aerial stems, bearing slender Juncus effusus, See also:common rush. I Plant. 4.

Seed. slightly enlarged. 7. Seed, much enlarged. leaves which are grass-like or cylindrical or reduced to membranous sheaths. The small inconspicuous See also:flowers are generally more or less crowded in terminal or lateral clusters, the See also:form of the inflorescence varying widely according to the manner of branching and the length of the pedicels. The flowers are hermaphrodite and See also:regular, with the same number and arrangement of parts as in the order See also:Liliaceae, from which they differ in the inconspicuous membranous See also:character of the perianth, the See also:absence of See also:honey or See also:smell, and the brushlike stigmas with See also:long papillae-adaptations to See also:wind-See also:pollination as contrasted with the methods of pollination by See also:insect agency, which characterize the Liliaceae. Juncaceae are, in fact, a loss elaborated See also:group of the same series as Liliaceae, but adapted to a simpler and more See also:uniform environment than that larger and much more highly See also:developed family.
