THISTLE , a name, as generally employed, of vague application, being given to almost any herbaceous plant that is of a spiny See also:character. More strictly, it is applied to the See also:species of Carduus. These are Composite herbs with very spiny leaves, and similar bracts surrounding a See also:head of purplish-See also:- WHITE

white, tubular, five-parted See also:flowers seated on a pitted and hairy receptacle. The anthers have appendages both at the See also:apex and at the See also:base, and the See also:style has a See also:ring of hairs at the point of bifurcation of the two stigmas. The See also:fruit is surmounted by a tuft of silky-white hairs. The species, chiefly natives of See also:Europe and Western See also:Asia, are numerous, and some are of See also:great beauty, though, not unnaturally, looked on with disfavour by the See also:farmer. The blessed thistle is Carduus See also:benedictus; See also:Lady's thistle, the leaves of which are spotted with white, is C. marianus. The See also:common C. lanceolatus seems to be the most suitable prototype for the Scots thistle, though that See also:honour is also conferred on an allied plant Onopordon acanthium, the See also:cotton thistle, remarkable for its covering of white down, a doubtful native, and on other species. The carline thistle is Carlina vulgaris, a member of the same See also:family as is also the sow-thistle, Sonchus oleraceus. The great objection to thistles from an agricultural point of view resides in the freedom with which they produce See also:seed, and in the vigour of their underground growth, which makes their uprooting a See also:matter of difficulty. Partial uprooting may, indeed, in the See also:case of the perennial species, increase the See also:mischief, for each fragment See also:left behind may grow into a distinct plant. See also:Annual species might be kept in check were they cut down before the flowers appear, but unless all the cultivators in a particular See also:district co-operate the efforts of individuals are of little avail. The See also:Artichoke (q.v.), Cynara scolymus, and See also:Cardoon (q.v.) are very near See also:allies of the thistles. The See also:Safflower, Carthamus, another thistle, yields a serviceable dye, the Burdock, Arctium See also:lappa, a member of the same family, has an edible See also:root; and numerous allied species have medicinal properties.
