doubtedly the most numerously represented tree present. Though really a littoral 

 species, it is not here confined to the shore, but extends from base to summit of the 

 outer cone on both sides wherever there is soil suitable for it to grow. Its general 

 dispersal in the island has been largely assisted by the rats ; they carry off the 

 fruits in order to eat the fleshy outer portion. 



45. Gyrocarpus Jacquinii Roxb. Narcondam (40). 



Africa; India, Indo-China, Malaya; Polynesia: not in the Mas- 

 carene Islands or E. Africa.

 India, Indo- China, Malaya ; Australia. 



47. Barringtonia speciosa Forst. Narcondam (43). 

 Ceylon ; Andamans, Malaya ; Australia ; Polynesia. 



The fruits of this species were picked up on the beaches in Barren Island, but 

 the tree itself was not found growing.

This plant, which is common in the valley between the cones, close to the lava, 

 is one of the species reported by the Deputation of 1866; flowering specimens col- 

 lected then are preserved in the Calcutta Herbarium, but are noted as being from 

 Narcondam, not Barren Island. The species does not appear to occur in Narcondam, 

 for the plant was carefully looked for there. The mistake on these tickets, which 

 requires to be pointed out, since some of the specimens collected in 1S66 may have 

 reached Herbaria in Europe, is nevertheless a fortunate one, as it first called the 

 attention of the writer to the fact that, though this Deputation only reported on 

 Barren Island (Proc. As. Soc, Beng., 1866, 215), it visited Narcondam also. The 

 interest of this fact will be shown in discussing the presence of the Coco-nut. 



The species has here, owing to its situation, developed a shrubby habit, but care- 

 ful examination of the complete material obtained by the writer, leads him to 

 conclude that it cannot be looked upon as even varietally distinct,
