    402. Datura Stramonium, L. a. Leaves. b. Seed. Note.—The leaves resemble those of Henbane in shape and in being toothed at the margin, but are not hairy, and the stem leaves are stalked, not sessile as in Henbane. For fig. of plant, see Bentley and Trimen, Med. Plants, tab. 192. 403. Hyosctamds niger, L. a. Leaves. (Annual Henbane.) b. Ditto. (Biennial Henbane.) c. Seed. Note.—The radical stalked leaves of the biennial plant are often sold as- Annual Henbane. In the Annual Henbane plants the small radical leaves are withered before the plant blossoms, therefore all the leaves in the annual drug should be without stalks. For the seed, see P. J. [2], vol. ix., p. 233. Henbane leaves may be known in the dried state from Stramonium by the leaves being hairy, not smooth, and from Belladonna by the leaves being toothed in the margin. For fig. of plant, see Bentley and Trimen, Med. Plants, tab. 194. 404. Nicotiana Tabacum, L. a. Leaves. (Tobacco.) Note.—Tobaceo is yielded by several different species. N. Persica yielding the Persian; N. rustica the Latakia, Turkish, and Manilla ; N. repanda the Cuban and Havana. See Bent. Man., p. 580 ; P. J. [1], vol. iii., p. 342 ; P. J. [3], vol. ii., p. 566. For fig. of plant, see Bentley and Trimen, Med. Plants, tab. 191. OLEACEJ3. 405. Fraxinus Ornus, L. (Manna Ash.) a. Section of stem, showing manner of incising the bark. See P.J. [3], vol. iii., p. 422. b. Flaky Manna, on pieces of stick, as collected. (Manna a cannolo.) c. Flaky manna, a commercial specimen. d. Artificial manna, made in France, Presented by Mr. H. S. Evans. See P. J. [1], vol. 1, p. 603. e. Ditto. Presented by Mr. W. W. Stoddart. /. Mannite. See P. J. [1], voL vi., p. 183. Note.—Manna is not now produced in Calabria as an article of com- merce. P. J. [3], voL iii., p. 422 ; P. J. [2], vol. xi., p. 326. Artificial manna either contains no mannite at all, or not more than 40 per cent., while true manna contains 70-80 per cent. Spurious manna is known by its uniform colour and freedom from the slight impurities, as well as from the peculiar odour and slight bitterness of manna. P. J. [1], vol. iv., p. 567. Mannite occurs also in many other plants. See Miller's Chem., pt. iii., p. 321; P. J. [1], vol. iv., p. 567 ; [1], vol. viii., pp. 480-482; [l],vol. x., p. 124; [l],vol. xvi., p. 530; [2], vol. xi., p. 629. For Artificial Mannite, see P. J. [3] ,vol. i., p. 864.
