روء

رَاآءٌ ذ A kind of [ plant, or] tree, (T, * S, M, K, &c.,) that grows in plain, or soft, land, (T, M, TA,) having a white fruit: or, as some say, a kind of dust-coloured tree, having a red fruit: (M, TA:) n. un. رَاآءَةٌ: (T, S, M, K:) and dim. ↓ رُوَيْئَةٌ: (M, TA:) AHn says that the راآءة is not taller nor broader than a sitting man: and accord. to one of the Arabs of the desert of 'Omán, it is a tree that rises on a stem, and then there branch forth [so in the M, but accord. to the TA, rise, ] from it round, rough leaves: others, he adds, say that it is a small tree of the mountains, resembling an عظلمة [q. v.], having a soft white flower like cotton: (M, TA: [but in the latter, the word rendered “ soft ” is omitted:]) some say that it is a species of the kind of tree called طَلْح [ acacia, or mimosa, gummifera ], and is the tree that grew at the cave in which were the Prophet and Aboo-Bekr: so say Suh and others: it is, they say, of the height of a man, and has white flowers, resembling cotton, with which cushions are stuffed, like feathers in lightness and softness: it is said by IHsh to be the same [ tree ] that is called أُمُّ غَيْلَان [see art. غيل]; but they have found fault with him. [for so saying]: it is not the عُشَر [ asclepias gigantea ], as one author has supposed; but a tree resembling this: (MF, TA:) such is the truth: the راآء is not the عشر: I have seen them both [says SM] in El-Yemen; and with the fruit of each of them cushions and pillows are stuffed: but the fruit of the عشر commences small; then increases to the size of the باذنجانة [or fruit of the egg-plant, and much larger, like a bladder]; and then breaks open, disclosing what is like cotton: and the fruit of the راآء is not thus: the عشر [he adds] is not found in Egypt; but it and the راآء are peculiar to El- Hijáz and the neighbouring parts; [in saying this, however, he errs; for I have seen the عشر in abundance in the deserts of the upper part of the Sa'eed;] and the saddles of camels &c. are stuffed with the fruit of the راآء in El-Hijáz.
