It has a deep yellowish or reddish-brown colour, and is so thick 

 that it solidifies at F. 60°. I believe that this species also 

 possesses in its stem fish-poisoning qualities, but much weaker 

 than the other. 



6. Millettia sericea, W. and Arn. (Leguminosx). In Malay- 

 Tuba gatel. Another genus of climbing papilionaceous plants, 

 closed allied to Wistaria, with which it is united by von Mueller 

 and others. It is only distinguished from such genera as Tephro- 

 sia, Pongamia, Robinia, &c, by minor peculiarities, especially 

 about the seed-pod. It is much sought after as a fish-poison, and 

 by some of the natives is preferred to any other. 



7. Millettia rostrata (?) Miq. Malay name Tuba-lalur. 

 Another species to which the same fish-poisoning properties are 

 attributed. 



8. Hartighsea acuminata, Miq. (Meliacece). This is a some- 

 what large tree belonging to a genus which has representa- 

 tives in Australia and New Zealand. In the latter islands its 

 leaves have a bitter taste, and are used as a substitute for hops, or 

 as a tonic. In Malay it is called Tuba-siapa, and on the west coast 

 of Sumatra, at least, is extensively used as a fish-poison, but I do 

 not know what part of the plant is employed. 



9. Polygonum barbatum, L. (Polygonacece). Malay name 

 Jukut-jaran or jarang. This species is common in tropical Asia, 

 Africa and Australia. It is used as a fish -poison in many portions 

 of the Archipelago, and I believe it is the same species which is 

 used by the natives of Australia for the same purpose. 



10. Tephrosia (Leguminosce). A genus which has many fish- 

 poisons amongst its species, for any representative of which I have 

 searched in vain in the Oriental region. In Australia, however, 

 we have a great number of species, about 28, It will assist the 

 comprehension of the previous remarks to mention what is said by 

 Lindley, (Veg. King. 2nd edit. 1847, p. 549.) "Many Tephrosias 

 are employed as fish-poisons especially T. toxicaria, the young 

 branches of which, with the leaves pounded, and sometimes mixed 

 With quick-lime, are thrown into a pool of some mountain stream,
