lected before maturity. The tree is about 25 feet high, with fruits the 

 size of a large cherry." 



52511. Inga laueina (Swartz) Willd. Mimosacese. 



"A small ornamental tree native to South America, which is culti- 

 vated in Singapore." 



A tropical American tree, 9 to 15 meters high, with leaves composed 

 usually of four leaflets; the flower clusters are longer than in other 

 members of this genus. As a shade tree for coffee this species is second 

 in importance only to the " guava " {Inga vera). Specimens have been 

 found, in some cases at least, with tubercles on the roots. The tree is 

 one of those employed in the cacao cultivation of Guadeloupe in making 

 hedges or Avindbreaks which are planted across the direction of the 

 prevailing winds at distances of 100 meters. (Adapted from Gook amd

From Moulmein, Burma. Seeds collected by J. F. Rock, Agricultural Ex- 

 plorer of the United States Department of Agriculture. Received Feb- 

 ruary 21, 1921. Quoted notes by Mr. Rock. 



" 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 water- 

 courses near the Karen village of Oktada, several miles from Paung, in the 

 Martaban Hills, on the Kalama Mountain Range. The trees must be planted 

 In gravelly, well-drained soil. 



" Strange to say, the people in Moulmein know nothing about this tree, and 

 the superintendent of the leper asylum here did not know that the tree grows 

 at all in Burma. 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 inter- 

 rogated 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."
