452. ClNNAMOMUM AEOMATICDM, Nees ; ClNNAMOMUM CASSIA, Blume. 



t a. Section of trunk, polished. 



Note. Attached to this specimen is a memorandum by Dr. Pereira to 

 the effect that he believed it to be derived from Litsasa zeylanica, and 

 not from the cassia-tree. Its bark has not the taste of cassia. 



b. Bark. (Chinese Cassia, an original bundle.) 



Note. For an account of the cassia-trees of China, see Porter Smith, 

 Chinese Mat. Med., p. 52. 



c. Bark. (Manilla Cassia.) 



Note. This is the bark described by Pereira in his Mat. Med., vol. ii., 

 pt. i., p. 446. It differs from ordinary cinnamon, in having the epidermis 

 imperfectly removed. It is possibly the produce of C. Burmanni, Bl. 

 See Pharmacographia, p. 475. 



d. Bark. (Singapore canella.) 



e. Ditto. (Cassia from Calcutta.) 



Note. Specimen e is in long smooth thick quills, and has a taste 

 reminding one of the smell of brown Windsor soap. It is labelled in 

 Hanbury's writing, " Bark from Calcutta, sold in London as Cassia vera." 

 It is probably obtained from another species, perhaps C. Tamala. 



Specimen d does not differ from ordinary cassia, except in having a 

 pale greyish fracture. 



/. Oil of cassia. 



Note. Oil of cassia is sometimes adulterated with oil of cloves. This 

 may be detected by the action of nitric acid, which causes oil of cassia to 

 crystallize, if pure; but only to swell up, and form a thick brown oil if 

 oil of cloves be present. See P. J. [1], vol. xii., p. 602; for artificial 

 oil of cassia, P. J. [1] , vol. xv., p. 180. 



g. Flower-buds, cassia buds. 



Note. Cassia buds are supposed to be the flower-buds of the tree 

 which yields Chinese cassia bark. Pharmacographia, p. 479. See also 

 Porter Smith, Chinese Mat. Med., p. 53. Cassia buds are used in con- 

 fectionery and hi Pot Pourri. See Bentl. <& Trim., Med. Plants, tab. 223. 



453. 'ClNNAMOMUM CULILAWAN, Bl. 



f a. Section of stem. 

 &. Bark, in flat pieces. (Culilawan BarJc, Indian Clove 



Bark.) 



Note. This bark has exactly the taste of allspice. It occurs in thick, 

 flat pieces. This bark must not be confounded with Brazilian clove 

 bark, which occurs in tubular quills, packed one inside the other, and 

 has a taste like cloves. Lindl. Flor. Med., p. 331; Per. Mat. Med., 

 vol. ii., pt. i., p. 437. For fig., see Goebel und Kunze, taf. xxvii., fig. i-v. 



454. ClNNAMOMUM INERS, 



a. Fruit. 



Note. These fruits are used in Southern India instead of cassia buds. 

 Their taste is not so agreeable. Pharm. Ind., pp. 195, 460.
