THE OHAULMOOGEA TREE AND RELATED SPECIES. 15 
TARAKTOGENOS KURZII. 8 
Taraktogenos kurzii was described by Sir George King from speci- 
mens collected by S. Kurz in Pegu Toukyeghat, Burma. These speci- 
mens had been erroneously identified by Kurz as Hydnocarpus hetero- 
phylla Blume {Taraktogenos olumei Hassk.), a species occurring in 
Java. There are three sheets of Kurz's specimens in the Calcutta 
Herbarium, two of No. 532 from Pegu Toukyeghat and another, No. 
1822, from Pegu Chonuymenah. There are no recent collections of 
this species, unless one recognizes as Taraktogenos kurzii the Thin- 
ganyinon plant 9 from Lower Burma, collected by Dr. I. H. Burkill, 
now of Singapore. This, to the writer's mind, is not permissible, 
owing to the difference in the fruits. 
It was the writer's object to locate Taraktogenos kurzii in its native 
habitat and to look up especially all those localities from which 
Taraktogenos seeds are brought to European chemists in India, in 
order to ascertain whether or not the seeds they are using are those 
of this species. Taraktogenos kurzii is evidently widely distributed 
in Burma. Numerous localities were given where kalaw trees may 
be found, as, for example, in Burma, at Chongnakwa, Lower Burma, 
and also at Tabyo. These places can be reached from Moulmein by 
way of Kyain or Metan. These regions belong to the Attaran divi- 
sion. Whether the trees found are the true Taraktogenos kurzii or 
not is an unsettled question, as material from these localities is not 
known, save seeds collected by natives. It is very likely that they 
represent Hydnoearpus castanea. 
The writer was informed by the Rangoon forest office that the 
true species was found in the upper Chindwin district, and espe- 
cially in the neighborhood of Mawlaik. To reach Mawlaik it is 
necessary to go by train to Myonhaung, where another train is taken 
to Amarapura, on the shore of the Irrawaddy, only a few miles 
from Mandalay; thence by ferry across the Irrawaddy to Sagaing 
and by train to Monywa, on the upper Chindwin River. It is sup- 
posed that Taraktogenos kurzii can be found even near Mandalay 
and lower down in the forests of Pegu ; in fact, the latter place is 
the type locality, where Kurz collected his original specimens. From 
Monywa a stern-wheeler requires four days to reach Mawlaik. This 
latter locality the writer visited. The Chindwin is a very winding 
river and in the winter navigation is very difficult, owing to the 
shallowness of the water and the constant changes of the channel. 
8 Taraktogenos kurzii King (13; p. 123). Specimens collected by the writer are 
deposited in the United States National Herbarium : Rock No. 802, U. S. N. H. No. 
1,090,010 ; Rock No. 814, U. S. N. H. Nos. 1,090,011 to 1,090,014 ; Rock No. 897, U. S. 
N. H. Nos. 1,090,019 to 1,090,021. 
9 Specimens were also collected by the writer and are deposited in the United States 
National Herbarium : Rock No. 694, U. S. N. H. Nos. 1,090,005 to 1,090,007.
