CONVOLVULACE^E. 



52. Erycibe panicdlata Roxb. var. peguensis, Clarke. A small 

 subscandent wide-spreading tree ; leaves elliptic cuneately acuminate ; 

 at both ends secondary nerves scarcely visible beneatb with dense pan- 

 cles, wbite flowers and rusty-tomentose shoots. The present locality 

 stands intermediate between those hitherto recorded for the variety — 

 Chittagong (Hooker,) and Moulmein (several collectors). 



53. IposiiEA GRANDIFLORA Lamk. Very common, climbing amongst 

 the Coast species on the western and northern sides of the Island, and 

 also for a little way amongst the adjacent inland species. 



54. I. dtgitata Linn. Common with the preceding on the western 

 side of the Island. 



55. I. denticulata Choisy. By the side of the stream between 

 the boat-house and the pilots' house, beside the path from the boat-house 

 to the telegraph-office, along the cleared slope between the telegraph- 

 office and the sea, and again at the north-east corner of the Island, al- 

 ways plentiful. The distribution of this species, so far as was known in 

 1883, was (P. B. I. iv, 208) " Malay Peninsula ; from Mergui south- 

 " wards. Ceylon; near the sea at Galle. Nicobars," its further dis- 

 tribution being " Malaya, Australia, Polynesia, Seychelles." But it is 

 now known to extend further up the Bay. It occurs in the Andamans, 

 is exceedingly plentiful on the Great Coco, was collected by Kurz at 

 Kobah on the shores of S. Burma during his latest journey, is very 

 plentiful here in Diamond Island, and was collected by Kurz at Akyab 

 which is still further north. In the Great Coco a curious feature in this 

 species and the next is their habitat. This species converts raised 

 coral " shingle " beaches into purple meadows ; on this shingle not a 

 single plant of I. bilooa is to be met with ; flat crescentic stretches of 

 level sand at the heads of bays are completely covered with I. biloba 

 and not a plant of I. denticulata is to be seen. Whenever a little cleared 

 patch of soil occurs near the sea the two sjaecies appear in it plentifully 

 side by side. 



56. I. BILOBA Porsk. Sand-beaches on north and west side of 

 island, not plentiful. Also with the preceding species between the 

 boat-house and the telegraph-office. 



SOLANACE^E. 



57. Capsicum minimum Roxb. In the telegraph-master's garden, 

 cultivated ; but also all over the central clearing, spontaneous. 



SCROPULARIACEYE. 



58. LiMnophila conferta Benth. ; Hook. f. In marshy ground 

 along with Hijdrolea.
