1890. J D. Prain — A List of Diamond Island Plants. 279 



LEGrUMINOS^E. 



19. Desmobium umbellatum DO. Shore species ; frequent, especi- 

 ally on the west and north sides of the Island. 



20. Abrus precatorius Linn. Very frequent everywhere in the 

 Island. 



21. Ertthrina indica Lamk. A purely coast species here, as it 

 also is in the Andamans and in Great Coco island. In the Great Coco 

 it is, however, rather uncommon : a striking contrast with the conditions 

 in Diamond Island where this tree forms an almost unbroken ring round 

 the coast. 



22. Mucuna monospermy DC. Very common in the interior 

 jungle. 



23. Pueraria phaseoloides Benth. Common on the western sea- 

 face of the Island, climbing over bushes of Taberncemontana crispa and 

 creeping in the grass at the bare south-western corner of the Island. 



24. Canavalia ensiformis DC. A climber all round the coast, 

 especially common on west and north sides of the island ; not met with 

 in the interior. 



25. Pongamia olabra Vent. Frequent in the line of trees imme- 

 diately behind the sandy beach. 



26. Cesalpinia Bonducella Ham. A thicket behind the boat- 

 house. 



27. Cassia alata Linn. Two or three large thickets between the 

 telegraph-office and the tank. 



28. TamarinduS indica Linn. Several large trees behind the 

 beach, between the telegraph-office and the graveyard. 



29. Entada scandens Benth. Common all over the island. 



30. Albizzia procera Benth. A common tree, especially in the 

 western half of the island ; those trees exposed to the S. W. monsoon 

 are gnarled and dwarfed and weather-beaten. 



COMBRETACE^E. 



31. Terminaua Catappa Linn. Frequent in the beach ring of 

 trees. One tree overhanging the boat-house, and probably an intro- 

 duced one, was in flower in November ; the others were all, as they were 

 in South Andaman and in the Great Coco, in fruit. 



MELASTOMACE^. 



32. Osbeckia chinensis Linn. ; C. B. Clarke in F. B. I. Frequent 

 in the bare grassy slope at the south- western corner of the Island. The 

 form present in Diamond Island differs from typical 0. chinensis some- 

 what in size and form of leaves and calyx ; in these specimens, leaves
