1891.] D. Prain — Little Andaman and the Nicohars. 161 



In the two subjoined lists the plants obtained during this short tour 

 are enumerated. The first list gives, for the sake of convenience, those 

 collected in Little Andaman. Species for which their occurrence here 

 is the first indication of their presence in the Andaman group are disting- 

 uished by an asterisk. 



The second list gives the plants obtained in Car Nicobar and in 

 Batti Malv. Those for which this is the first record of their occurrence 

 in the Nicobars and which are not given in the Enumeration of the plants 

 of the Nicohar Islands by Mr. Kurz (Journ. As. Soc. Bencj., xlv, pt. 2, 

 p. 115 — 164) are similarly distinguished.

5. Carapa oboyata Blume. 



Having seen both G. ohovata BL, and C. malaccensis Lamk. in situ 

 and examined them as they grow, it is very difficult for the writer to 

 give his assent to the proposition that treats the two as conspecific. 

 G. moluGcensis is common on rocky coasts, while G. ohovata is confined to 

 muddy flats, in which it is common, and to mangrove-swamps, of the 

 vegetation of which it forms an integral portion. There is no difficulty 

 with the large suites of specimens that are preserved in the Calcutta 

 Herbarium in distinguishing the one plant from the other, and the re- 

 sidents of Port Blair who know both find it impossible to understand 

 why botanists should wish to believe them to be the same. It may be 

 that their differences, so palpable to the untrained eye, are altogether due 

 to the environment of the two being so different ; this, however, if it be 

 a fact, can only be demonstrated by experiment and the onus prohandi
