medullary rays being white and large in proportion to the porous woody 

 tissue. Iodine turns a decoction of the root bright blue. Pharmaco- 

 graphia, p. 29. 



22. ANAMIRTA COCCDLUS, Wight fy Arnott ; ANAMIRTA PANICULATA, 



Colebroolce. (flocculus Indicus.) 



a. Fruit. 



Note. The fruit resembles bayberries in appearance, but is known by 

 being slightly depressed on one side and by the crescent-shaped seed. 

 Picrotoxin is contained in the kernel ; menispermia in the shell. For 

 Detection of Picrotoxin, P. J. [3], vol. v., p. 567. For fig. of plant, see 

 Bcntley and Trimen, Med. Plants, tab. 14. 



23. CISSAMPELOS PAREIEA, Lam. 



a. Root. Presented by Mr. D. Hanbury. 



Note. This root is distinguished from that of Chondodendron by hav- 

 ing only one woody zone, and by not being larger round than the 

 forefinger. For fig. see P. J. [3], vol. iv., p. 102. For fig. of plant, see 

 Bentley and Trimen, Med. Plants, tab. 15. 



24. CHONDODENDRON TOMENTOSUM, E. et P. (Pareira Brava, Butua.) 



* a. Specimen of leaves, stem, root, and fruit, mounted in a 



glass case. Presented by Mr. D. Hanbury. 

 &. Fruit, preserved wet. Presented by Mr. D. Hanbury. 



c. Root. 



Note. This specimen (c) originally belonged to Pereira, and is the one 

 from which the description given in his work is partly taken. Pereira, 

 Mat. Med., vol. ii., pt. ii., p. 671. For fig. of fruit, see P. J. [3] , vol. iv., 

 p. 83. For fig. of plant, see Bentley and Trimen, Med. Plants, tab. 11. 



d. Root. A very large specimen. 



e. Ditto. A commercial specimen. 



Note. Specimen e shows well the dark colour and transverse ridges 

 characteristic of the true Pareira Brava. For fig. of the root, see P. J. [3] , 

 vol. iv., p. 102. Goebel und Kunze, pt. ii., taf. xiii., fig. 1. 



Iodine gives a bluish black colour with decoction of the root. 



/. Stem. 



g. Ditto. A commercial specimen. 



Specimen / is a portion of prostrate stem, with root on its lower 

 surface. Specimen g exhibits the paler coloured bark, and the numerous 

 small warts on the exterior, which, together with the absence of trans- 

 verse ridges and the presence of lichens, always distinguish the stem 

 from the root. It is less bitter than the root. P. J. [3], vol. iv., p. 911. 

 For micr. structure of the stem, see P. J. [3], vol. vL, p. 702. 



h. Common false Pareira Brava. 



Note. This specimen consists of the stem of an unknown plant. It 

 is characterised by having an excentric pith, and only one perfect zone 

 of wood, all the others being incomplete. For fig. see P. J. [3], vol. iv., 

 p. 103. 



Iodine does not give a blue colour with the aqueous decoction of this 

 stem.
