بَرْدِيٌّ

A well-known kind of plant, (S, M, * K,) of which the kind of paper termed قِرْطَاس is made; (TA in article قرطس, q. v. ;) [namely, papyrus; and] of which mats are made; (Msb;) [apparently meaning rushes in general: but the former is generally meant by it in the present day, and is probably the proper signification: anciently, mats, as well as ropes and sails &c., were made of the rind of the papyrus; and even small boats were constructed of its stalks bound together; and of such, probably, was the ark in which the infant Moses was exposed: it is a coll. gen. n.:] n. un. بَرْدِيَّةٌ. (M, TA.) Hence, قَطْنُ البَرْدِىّ The cotton of the papyrus, which, resembling wool, is gathered from the stalk, and, mixed with lime, composes a very tenacious kind of cement. (Golius, from Ibn-Maaroof.)

[Also, a rel. n. from the same, meaning Of, or belonging to, or resembling, the plant so called. Hence the saying,] لَهَا سَاقٌ بَرْدِيَّةٌ [She has a shank like a papyrus-stalk]. (A.)
