16 BULLETIN 1057, U. S. DEPARTMENT OF AGRICULTURE. 
The first definite information regarding the presence of kalaw trees 
in the neighborhood was obtained at Maukkadaw. It was reported 
that the trees grow plentifully but in restricted areas some 20 miles 
from Maukkadaw, at Chingyon Ohndon, district of Kyongyi, in the 
Hkaungdan forest. Lack of time prevented the writer from investi- 
gating these forests on the upward journey. However, seedlings 
were secured from this region on the return journey to Rangoon. 
Of these seedlings one reached Hawaii in good condition and is now 
flourishing. 
On arrival at Mawlaik, the writer called at the forest office and 
received the following information: 
The presence of Taraktogenos Tcurzii is known to us only through natives 
who take out licenses for collecting the seeds, after the rainy season, in three 
localities. 
These localities are at Maingyaung, some 50 miles from Mawlaik, 
and at Khoung Kyew and Kyokta on the Khodan (or Khodaun) 
stream. The writer engaged a dugout canoe and with a cook, a boy, 
and an interpreter followed the Chindwin in its downward course as 
far as Chaing (Kyaing), whence the overland journey through dense 
forests commenced, first to Nansouksouk and thence to Thoung 
Dwin ; the next stop was at Khoung Kyew. This is a small village 
situated on a bend of the Khodan stream, facing dense forests on 
the opposite bank. The soil consists largely of quartz sand, save in 
the flatlands, which are of clay or rather loamy and inundated 
during the rainy season, which extends from May to October. The 
river bottom is all sand and not a single rock is encountered any- 
where. After Thoung Dwin the land is undulating and somewhat 
hilly, but no high elevation is reached. The forest is very dense and 
has a forbidding appearance. It is composed of Oephalostachyum 
pergracile, Ficus spp., Garcinia spp., Terminalia spp., Quercus 
spp., and various Dipterocarpacese, Euphorbiacese, Meliaceae, and 
Leguminosae. The undergrowth is formed of ferns, Clerodendron 
spp., various Acanthacese, etc. 
At Khoung Kyew the headman, or tajee, of the village, several 
coolies, the interpreter, and the writer started out in search of kalaw 
trees. Two localities were visited, one by following a narrow creek 
bed with running water. Here the trees were very tall, some 50 to 
60 feet. Taraktogenos kurzii covered the steep hillsides, which were 
pure grayish loamy quartz sand. Some trees were actually growing 
in the stream bed. The whole area supporting the kalaw trees was 
very small and was restricted to about 30 or 40 acres. It was a 
dense tropical and humid forest, though very cool at this time of 
the year (January, 1921). There were many climbers, such as 
Tkunbergia laurifolia, while the undershrub was composed, espe- 
cially along the stream bed, of an acanthaceous species {Phlogacan-
