1891.] D. Prain — TJie Vegetation of the Coco Group. 315 



115. Lagerstrqbmia sp. 



Little Coco ; one tree only seen. 



A tall straight tree, about 100 feet, leaves sessile, oblong-lanceolate 

 8 in, long, 2j-2f in. wide, thinly coriaceous, fruit | in., calyx woody, 

 lobes spreading. 



The leaves of this are unlike those of any Indian species ; the fruit 

 is very like that of L. calyculata Kurz, from Martaban, but the leaves aie 

 very different, being larger, much thinner, and perfectly glabrous. 

 This, when flowers are found, will almost certainly prove a distinct 

 species. 



PASSIFLORE^. 



116. MoDECCA GORDiFOLiA Blume (fide Masters). 

 Great Coco, common. 



Andamans ; the specimens are exactly like the common Andaman 

 coast Modeoca and the flowers appear not to differ from those of M. cardio- 

 pJiylla Mast. 



117. Carica Papaya Linn. 



Great Coco, introduced but perfectly naturalised and already ex- 

 tending in an unbroken line among the coco-nuts on the east coast, 

 from the north-east corner to within 3 miles of the soath end of the island ; 

 one or two isolated specimens occur at the south-east corner evidently 

 oi-iginating from fruits washed up by the sea. Half a mile from the 

 south end on the west coast is another spot, well into the interior, where 

 some trees occur — the result apparently of independent introduction as 

 they occur near the remains of some huts used by coco-nui gatherers 

 who visit the island at intervals. 



Cultivated in warm countries ; originally American. 



CUCURBITACE^. 



118. Trichosanthes palmata Roxb. 

 Little Coco ; near north end of island. 



India, Ceylon ; Burma, Andamans ; Malaya ; N". Australia ; China, 

 Japan. 



FICOIDE^. 



119. Sesuvium Portulacastrum Linn. 



In all the islands ; common on sandy beaches on the east coast. 

 All tropical and sub-tropical sea-shores.
