A SCIENTIFIC EXPEDITION TO TEMENGOH. 22 
This plant is common in the Singapore woods at 
Chua Chu Kang, Bukit Timah (8398), Kranji (6388), 
Stagmount (14144), Changi (3603.) Also I have met 
with it in Johor at Tebing Tinggi and Kuala Sembrong 
(Kelsall. ) 
A very similar plant with fewer nerves and more 
glabrous flowers was collected by Dr. Haviland (973) at 
Kuching, It also occurs atin Perak at Tapa (Wray 
1329); Pekan, Goping in Perak (Kunstler 4718) ; Penang 
(Curtis 1566). Another form has usually smaller leaves 
and is pubescent on the branches petioles and veins on 
the back of the leaf, and this I have only seen in villages. 
I have it from a cultivated plant quite thornless (11366, 
468); Perak, Thaiping (Wray 2399, Kunstler 2858) ; 
Krian, (Wray) and Simpang, (Wray 2041); Malacca, 
Ayer Bumban (Cantley), Bukit Bruang (R. Derry 1200), 
and this is the Temengoh plant. 
These two forms may not be even varietally different, 
but are I think worth noting. 
F’, nermis, Roxb., has hermaphrodite flowers, no thorns and an 
acid fruit, Jack records it and describes it from Penang. 
The styles are free. A plant with rather thin large 
leaves from the Penang gardens collected by Mr. Curtis 
and by him named fF’. inermes, has the styles connate 
something like those of F’. Calaphracta, but itis not that 
species. JI have only seen fruit of it. 
F. Cataphracta, Bl. Is a thorny tree with branched 
thorns on the trunk and straight species on the young- 
shoots from the stool. The branches are not spiny, 
and trees can often be met with few or no spines 
anywhere. The leaves are small, lanceolate acuminate 
with entire edges or more often shortly crenulate 
denticulate dark shining green, red when first appear- 
ing. The flowers are unisexual in small axillary tufts.
