V plate 7). This is again described by Blame under the above 
name in Rumphia, but he adds to it the synonym of Gn. scandens . 
of Roxburgh, quite a different plant. 
From Mr. Vaughan Stevens I have received leaves and a 
sketch of the plant which he describes as used by the Sakais under 
the names of ‘ ‘Blay Merah* 5 ‘ ‘Blay KechiT * or among the Pan- 
ghans “Kenne.t,” The bark is used in the Antians mixture. 
No species of the genus are known to possess any poisonous 
properties. T , 
Several - plants are also mentioned as being added to the ipoh 
poison which apparently have no poisonous principles at all, 
but are mere irritants and probably act by causing a flow of blood 
to the wound and increasing the absorption of the poison, such ai e 
Piper stylosum, Miq., Blay Pendy (Vaughn Stevens), a low-grow- 
ing erect pepper about a foot tall. A Ipinici Gctlcnigci and Ain 
giber Cassumunaar, Black pepper (Lada hitam) and leeks and 
onions are also mentioned by Horsfield, and Newbold men- 
tions the use of Arsenic (warangan) and lime juice. The l^imei 
of these must be considered very doubtful, as it would probably 
have no effect at all, and could hardly be obtained by a Sakai 
living in the woods. 
Sedudu, mentioned by Vaughan Stevens, is apparently an un- 
described species of M edinilla. It is an epiphytic shrub, with 
opposite leaves lanceolafp, acuminate and denticulate, with shoit 
petioles. The flowers are axillary, two or three together, and 
the fruit is semi-transparent and white “like a white currant. 
The roots are used fresh, as their poisonous qualities disappeai 
when dry, according to the Panghans. The sketch and leaves 
I have from Vaughan Stevens are hardly adequate to iden- 
tify the plant, but it differs in many points from any other spe- 
cies of the genus which I have met with. Some of the Medinillas 
are acid, and allied plants often astringent, but I know of none 
with poisonous qualities. The name Sedudu (or Senduduk) is 
commonly applied to many of the Melastomacece. Two species 
of Rattan (Dcemonorops sp.) Rotan Riong and Rotan Butong aie 
also used, the sap from the cane being added to the decoction, 
according to Stevens, who also mentions plants called Bal, Grow 
(or Chow) Choichoi, Lendow and Garsung. The sketches and 
leaves I have of some of these are insufficient for identification. 
Newbold also mentions the “Chey,” but possibly this should be 
“Ches,” a Besisi name for Antiaris (Skeat). 
Other Malay Poisons. 
Derris elliptica, Benth. ( Leguminoste ). — “Tuba,” a low- 
climbing plant, often cultivated for use as a fish-poison. It is 
usually cultivated as a prostrate plant, the branches being allow- 
ed to straggle about on the ground. The roots are the parts used 
in catching fish, generally with the aid of lime, being pounded and 
mixed with the lime and water and thrown into river or arm of 
the sea. It is propagated by cuttings and grows fail ly rapidly. 
The poison is said also by Newbold to be mixed with Antiaris foi
