Roucheria Griffithiana, Planch. ( Linear ). — A common 
woody climber known as Bhoi by the Sakais, and Akar Ipoh 
putih by the Malays, the bark of which is used by the Sakais for 
mixing with the antiaris. The stem attains a thickness of about 
4 inches with a white bark (whence the name Ipoh putih). It 
possesses curious curved hooks by which it climbs on other 
bushes and trees. The leaves are small, lanceolate, dark green. 
The flowers numerous in axillary tufts are bright yellow. The 
fruits are small bright red drupes. 
Nothing is known as to the properties of this plant but, as it is 
evidently reckoned to have poisonous properties by the Malays 
and Sakais, it will be well worth examining. 
Lophopetalum pallidum, Laws ( Celastirnecz ) . — Krohi, 
Kruoi (Besisi dialect, Skeat), Krabu (Malay), is a gigantic tree 
with lanceolate, rather stiff leaves, about two or three inches 
long, turning glaucous when dry, with about eleven pairs of 
main nerves. The fruit a large, oblong capsule, woody, breaking 
up into boat-shaped valves, outside black and shagre'ened, inside 
shining brown, length about four inches, the seed flat with a long, 
brown wing as long as the capsule. 
This plant much resembles L. Curtisii, King, of Penang, but 
that has smaller and rounder leaves with fewer nerves, and I take 
it to be the little known L. pallidum, Laws. 
The Kroi is mentioned by Vaughan Stevens as used by the 
Menteras in combination with Tuba, and I have specimens of the 
leaves and wood from him. I found it was known to the Sakais 
of Selangor, some whom I met near the Batu Caves, evidently 
setting much store by it. Newbold (Malacca ii p. 399) talks of 
three preparations used by a tribe from Sungei Rhya — Ipoh 
Krohi, Ipoh Tennik or Kennik and Ipoh Mallaye, and says that 
the Ipoh Krohi is composed of Krohi (extracted from the Ipoh 
tree), Tuba, Kopah, red arsenic and lime juice, and Ipoh Tennik 
is made in the same way, omitting the Kopah. This is probab- 
ly erroneous, as Tennik is simply a Sakai word for Antiaris, and 
Kroi is an entirely different tree. 
The bark and outer part of the wood of the Lophopetalum are 
the parts used in the decoction. No examination of this tree has 
yet been made, but, as it is evidently considered a. valuable 
addition to the Ipoh, it probably contains some poisonous prin- 
ciple. Another species of the same genus, Lopho petalum toxi - 
cum, Loher, has just been described in the leones Buitenzor- 
genses (Vol. 1, p. 56, Fig. 16), of which the bark is used by the 
Negritos of the Philippines for poisoning their arrows. 
Aralidium pinnatifidum Miq. (, Araliaccce ). — Malai or Balai 
(Mallaye, Newbold), Tingal Balai, a shrub or small tree about 
twelve feet tall. The leaves are oblong and rounded at the apex 
or deeply lobed, being cut nearly to the mid-rib. They are usual- 
ly about a foot long. The flowers are small and greenish white, 
in large terminal panicles. The fruit is an elliptic oblong drupe,
