(a condition having the fruit so covered with lenticels that 
it appears different, and it is possible that when more: 
fully known it will have to be distinguished. ) 
Flowering specimens which seem to be Pachynocarpus Stap- 
fianus but cannot be assigned to it positively are King’s collector’s: 
No. 6594 from Larut, 5010-800 ft., with flowers in September 1884, 
his No. 5763 from Gopeng with flowers in April 1884, his No. 6070 
from Gopeng, with flowers in May 1884, Curtis’ No. 1218 from 
Sungei Penang Road at 1,000 ft. (doubtless the more western Sungei 
Penang of the two in the island of Penang); another collected 
by Curtis, without number, in September 1887, from the Hxperi- 
mental Nursery at 2,000 ft. on Government Hill, Penang, and a 
third with flowers in August 1880; King’s collector’s further 
specimens from the Bernam river bearing his number 8753, having 
been got in flower in April 1886; and lastly Barnes’ No. 10872 
from ‘Kluang Terbang at 5,000 ft. on Gunong Benom, Pahang, 
with buds. 
é 
Maisak is the Siamese name for this tree, and it is a Resak 
to the Malays. Resak laru is a name from Kuantan and also from 
Penang. 
Our conclusion is that Pachynocarpus stands with two or 
possibly three species, i.e. P. wmbonatus, Hook. f., possibly Py 
verrucosus, Burck, and P. Stapfianus, King; but that P. umbonatus 
must be collected again to remove some doubt as to the correct 
identification of the flowering specimens with the fruit. The rest 
of the species put by various authors into the genus go to Vatica..
