غَرْفٌ

and ↓ غَرَفٌ, (S, K,) the latter mentioned by Yaakoob, (S,) A species of trees, (شَجَرٌ,) with which one tans; (S, K;) when dry, [said to be] what are termed ثُمَام: (TA: [but perhaps this statement applies particularly to غَرَفٌ, which see below: and see also ثُمَامٌ:]) according to A'Obeyd, called غَرْفٌ and غَلْفٌ [q. v.]: AHn says, the غرف is a species of trees from which bows are made; [see عِضَاهٌ;] and no one tans with it; but Kz says that its leaves may be used for tanning therewith, though bows be made of its branches: and Aboo-Mohammad mentions, on the authority of As, that one tans with the leaves of the ↓ غَرَف, and not with its branches: El-Báhilee says that غَرْفٌ signifies certain skins, not such as are termed قَرَظِيَّة, [i. e. not tanned with قَرَظ, but] tanned, in Hejer, in the following manner: one takes for them sprigs (هَدَب) of the أَرْطَى, and puts them in a mortar, and pounds them, then throws upon them dates, whereupon there comes forth from them an altered odour, after which a certain quantity is laded out for each skin, which is then tanned therewith; and the term غَرْف is applied to that which is laded out, and to every quantity of skin from that mash, to one and to all alike: but Az says, the غَرْف with which skins are tanned is well known, of the trees of the desert (البَادِيَة), and, he says, I have seen it; and what I hold is this, that the skins termed غَرْفِيَّة are thus termed in relation to the species of trees called the غَرْف, not to what is laded out: As says that الغَرْفُ, with the ر quiescent, signifies certain skins that are brought from El-Bahreyn.
