Oct., V'l.v G. KOIDZUMI.—THE VEGETATION OF JALUIT ISLAND. 



Lepturus and Thuarea. There are no coconut trees on several 

 small islets, but the whole of the main island is densely covered 

 with them. The interior of the island is covered for the most 

 part with a dense growth of Allophvlus timorensis and Wedelia 

 hiflora, associating with few -beach trees such as Terminalia 

 catappa, Pipturus incanus, Cordia subcordata, Cerbera lactaria, 

 Hernandia peltata, Callophyllum Inophyllum and Ervthrina 

 indica. Ipomoea Pes-caprae is the most pronounced plant in the 

 sand-strand formation, which occurs only to a limited extent 

 on the sand-beaches at Jabor. The shores are not, I should 

 think, favorable for the germination of many kinds of seeds that 

 may be fortuitousely brought to them, being composed almost 

 entirely of coral blocks or coral sand. 



There is a little cultivation in the island, at the principal 

 habitation of Jabor on the south-east side of the island. In 

 gardens Bananas, Bread-fruit-trees, Ananas, Anonas, Taro, 

 Papaya, Lima-beans, Jack-fruit-trees and a few other tropical 

 fruits are grown. 



The following is a list of the flowering plants and ferns 

 naturally found in the island. I was careful not to collect 

 intentionally introduced plants by man.
