A SCIENTIFIC EXPEDITION TO TEMENGOH. 
Flacourtia Rukam, var. Ula Temengoh near the village. 
The Flacourtias known here as Rukam, seem to be 
in a very confused state botanically, and require more 
study from the living plants. Most of those in this 
region are only known in a cultivated or semicultivated 
state. They can be separated into two groups accord- 
ing to whether the styles are separated to the base or 
whether they are connate, with little more than the 
stigmas free. Threespecies are recorded from the Malay 
peninsula, viz., f’. Rukam, Zoll. Mor., F’. enermes, Roxb., 
and Ff’. Cataphracta, Bl. 
The first of these has free styles, the other two con- 
nate styles. | 
F. Rukam, Zoll. is described as an unarmed tree, but this, if 
my identification is correct, is not always the case. 
There seem however to be several forms of it. In one 
form the leaves are small and the tree is quite unarmed. 
The fruit has 6 to 8 styles quite free and widely separate 
on a flat top to the fruit. This is the species mention- 
ed above and I have only seen it in villages. A specimen 
sent to Dr. King many years ago was named F/.. Rox- 
burghit, but I cannot find thisname taken up anywhere. 
Another form is a straggling thorny tree with large 
leaves, and is the only really wild species in the penin- 
sula, inhabiting damp forests. 
This form of Ff. Rukam, has large elliptic cuspidate 
leaves, 6-7 inches long 24 inches wide, the cusp an inch 
long. The margin of the leaf strongly crenulate, and 
altogether glabrous. The flowers are unisexual in small 
tufts but more numerous than in Ff’. cataphracta. 
The pedicels are pubescent. Sepals and dise as in F. 
cataphracta. The sepals ovate obtuse pubescent. 
Stamens numerous. In the female the styles are sepa- 
rate stout and spreading. The fruit is rather larger, 
and the styles slender quite sepatanae and remote on the 
flattened top.
