Tabern.emontana malaccensis. Hook. fil. ( Apocynaceal ).— ■ 
Perachit Prachek ; a shrub usually of no great size with white 
flowers in corymbs and orange-coloured curved pods in pairs, 
containing seeds enclosed in a crimson aril; it is common in Singa- 
pore, Malacca and elsewhere. Perachit is mentioned as used in 
the manufacture of Ipoh poison by Newbold, 
It is used by the Malays in native medicine, the leaves and sap 
for poulticing boils, and a decoction of the bark is also used for 
syphilis as is that of the allied T. corymbosa, The roots are said 
by them to be poisonous- Several others of the genus have 
poisonous properties as T. dichotomy of India, of which the seeds 
are said to be powerfully narcotic, producing delirium and otheF 
symptoms like Datura, while the bark and leaves are said to be 
purgative (Dictionary of the Economic Products of India) and 
T. splicer oearp a, Bl., of Java, which is stated to contain an alka- 
loid. (Lewin Die Pfeilgifte.) 
Prismatomeris albidiflora, Thw, ( RuUacece > is used by the 
Menteras with the last mentioned plant under the name of Mun- 
dess. If is a shrub with white flowers, common in Singapore, 
Penang, and Sumatra. I do not know of its possessing any 
poisonous properties. The bark and roots are the part used. 
Laportea crenulata, Gaud. — This shrub or small tree be- 
longing to Urticacece is used with the Antiaris poison under the 
name of Rumpei according to Vaughan Stevens. The common 
Malay name for it is Jelatang. It is a soft wooded tree or shrub 
of no great size, with more or less oblong leaves, the petiole and 
part of the leaf armed with short stinging hairs. It is known in 
India as the Devil nettle or Fever nettle on account of its violent 
urticating powers. The flowers are produced in axillary panicles 
and are small and usually purplish. 
It is by no means common in the Peninsula, but occurs in Se- 
langor, Perak, Penang and Pulau Tioman. It is however very 
widely distributed, occurring in India and all over the Malay Ar- 
chipelago. No medicinal properties are attributed to it, and it 
is probably only added to the poison mixture because it is irri- 
tating, and therefore in the native mind must be suitable for 
making poison. The form in the Malay Peninsula appears to be 
not so irritating as that of India and the Malay islands, but if 
has been stated that the hairs only sting at certain times. 
Cnesmone Javanica, Miq. (Euphorbiacece ). — Jelatang Rusa ;
