122. Pholidota imbrtcata Lindl. Barren Island (54), inside crater. 

 India, Burma, Malaya.

123. Musa sapibntum Linn. The Plantain. Narcondam (104), a large 

 grove behind the Coco-nut trees at Coco Bay. 



Cosmopolitan in the tropics, cultivated. 

 No doubt deliberately introduced for the benefit of possibly ship-wrecked 

 mariners, though it is not quite clear who planted it ; probably (see under Cocos 

 nucifera) it has been introduced from the Andamans, and perhaps dates from 1866.

130. Cocos nucifera Linn. Narcondam (109), many at Coco Bay, 

 a few at Anchorage Bay, one, not yet bearing, at E. Bay; Barren Island 

 (58), thirteen trees counted from the offing, behind the Pandanus fence 

 at Anchorage Bay ; none seen elsewhere. 



India; Malaya; Polynesia; America. 

 The introduction of this tree into these islands is a question of some interest. 

 The tree at E. Bay, Narcondam, has no doubt been produced from a nut washed 

 round from Coco Bay ; in all likelihood the trees at Anchorage Bay have been 

 derived from the same source. The trees at Coco Bay itself may have origi- 

 nated from nuts brought from the Coco Group by a surface-current sweeping from 

 the Sea of Bengal, through the Preparis Channels, from N.-E. to S.-W. across the 

 Andaman Sea ; but as they are associated, where they occur, with a °-rove of 

 Musa sapientum (which must have been deliberately introduced), it is not unreason 

 able to suppose that the two species were introduced together.
