rubber producers do not seem to occur in the country. Some of the 

 rubber trees however have been introduced Hevea braziliensis, in- 

 troduced in 1 89 1, disappeared soon afterwards. It has however 

 been reintroduced and seems to do well in the region south of 

 Annam and can be tapped in six years. Ceara rubber does not seem 

 able to stand the dry season, at Saigon nor the cold of Hanoi. 

 Castilloa introduced in 1889 disappeared in 1900. Ficus elastica, 

 is indigenous in Annam and seems to offer the best hope of French 

 Indo-China becoming a rubber producing country.

FRUITING OP THE FRANGIPANI (PLUMIERA) 



The well known plants of the Genus Plumiera commonly called 

 Wangjpam are natives of South America with one or two in Atnca 

 and Madagascar, about fifty species are recorded but only about 

 eight are in cultivation. The best known of these is P. acuttfoha 

 which is cultivated ev-ry where and especially in grave-yards, where 

 very large specimens may often be seen. It has white flowers with 

 more or less pink backs. 



P. rubra is easily distinguished by its beautiful rose-coloured 

 flowers. It is not very common, in cultivation in the East, having 

 been introduced comparatively lately. 



These plants do not as a rule fruit very readily. It is quite rare 

 to see. P. acutifolia in fruit common as it is here>. rubra however 

 seems to fruit more easily. 



Mr Machado has latelv sent seeds from Kamuning Estate, and 

 it is fruiting too in the Botanic Gardens. The fruit consists of vo 

 follicles rather thick, and cylindric spreading out widely apart like 

 buffalo horns. The seed is about an inch long flat and oblong 

 trom its rather broad dry brown wings.
