سوس

سَوَاسٌ ذ A certain kind of tree: n. un. with ة: (M, K:) AHn says, (M, TA,) on the authority of Aboo-Ziyád, (TA,) it is of the kind called عِضَاه, resembling the مَرْخ, having a pericarp like that of the مرخ, (M, TA,) without thorns and without leaves, growing high; and persons shade themselves beneath it; one of the Arabs said that it is the same that is called ↓ سَوَاسٍ (written with the article السَّوَاسِى); and AHn says, I asked him respecting it, and he said that this and the مَرْخ and the مَنْح all three resemble one another; (M;) and it is one of the best of materials used for producing fire, (Lth, * M, K, *) not giving a sound without emitting fire, (M,) or because it seldom gives a sound without emitting fire. (Lth, TA.)
