Aleurites molueeana (Euphorbiaceae) , 52449. Candlenut or 
lumbang. From Mayaguez, Porto Rico. Seed presented by 
Mr. D. W. May , in charge , Agricultural Experiment Sta- 
tion. "Individuals here eat these nuts to some ex- 
tent, but occasionally they are made quite ill from them 
owing to the stage of ripeness of the nut or to some 
peculiar characteristic of the person that eats them. 
If they are eaten unripe- they act as a strong purgative ; 
if fully mature and roasted they are doubtless, in 
most cases, harmless. From the general experience in 
Porto Rico, however, I would advise eating them, if 
at all , with caution." (May.) 
"Candlenut, or lumbang, oil is used in soapmak- 
ing, and in the Philippine Islands the press cake Is 
highly prized as a fertilizer." (R. A. Young.) 
Hydnoearpus eastanea (Flacourtlaceae ) , 52514. From 
Moulmein, Burma. Seeds collected by Mr. J. F. Rock, 
agricultural explorer. "A large tree 50 to 80 feet in 
height, with smooth, light brown bark and fruits the 
size of a large orange, ripening from March to July. 
Only one tree among thousands was found with ripe 
fruits on January 7, 1921. It was loaded with ripe 
and semiripe fruits. The tree grows on steep rocky 
hills along watercourses near the Karen village of 
Oktada, several miles from Paung in the Martaban Hills 
on the Kalamia mountain range. The trees must be 
planted in gravelly well-drained soli. 
"Strange to say the people in Moulmein knownoth- 
ing about this tree and the superintendent of the 
leper asylum here did not know the tree grew at all 
in Burma. (True chaulmoogra oil, expressed from the 
seed of this tree, is very useful in the treatment of 
leprosy.) The foresters I met In the jungle never 
heard of the name 'Kalaw' which is the Burmese name 
of the tree. Many of the Burmese I interrogated knew 
the name but not the tree; they knew the seeds from 
the bazaars where they are sold. Only people actually 
making a living by collecting these seeds can give 
information." (Rock.) 
Inga lamina (Mimosaceae) , 52511 . From Bangkok, 
Siam.r Seeds collected by Mr. J. F. Rock, agricultural 
explorer. "A small ornamental tree native to South 
America, which is cultivated in Singapore." (Rock.) 
A tropical American tree 9 to 15 m. high, with 
leaves composed usually of 4 leaflets; the flower 
clusters are longer than in other members of this
