274 D. Prain — A List of Diamond Island Plants. [No. 4, 



in wliicli Eleusine indica is the only grass that appears in tufts ; behind 

 the boat house is a tangled patch of Gohibrina asiatica and Caesalpinia 

 Bonducella ; on the road leading from the boat hoase to the telegraph 

 office is a quantity of Ipomoea denticulata, at the back of the office a 

 large patch oi Adeyiostemma viscosum, between the office and the servants' 

 quarters a large patch of Ocimum dasilicicin, lower down and near the 

 tank two or three extensive patches of Cassia alata. Vernonia cinerea is 

 very common all over the older clearing, but Ageratum conyzoides, 

 usually such a common weed, is quite rare as yet. TJrena lohata is com- 

 mon towards the edge of the clearing nearest the jungle, but is less com- 

 mon than Melochia corchorifolia is ; the latter is also the commonest 

 weed in the newer clearing in the centre of the Island. Scoparia dulcis 

 is plentiful in both the old clearing and the new, but the common Sidas 

 are conspicuous by their absence. The wet soil near the edge of the 

 tank is covered with broad patches of Euphorbia thymifolia ; associated 

 with it is Vandellia Crustacea which is, however, less plentiful : nearer 

 the tank still, or even growing in the shallow water at the eastern end, 

 are Splienoclea zeylanica, Hydrolea zeylanica, Limnophila conferta, Scir- 

 pus artioulatus and Geratopteris thalictroides, all very profuse. In the tank 

 itself grows Nympliaea Lotus, but not very commonly ; the red form is 

 not present* ; Nympliaea stellata too is absent : Nelumhium speciosum, 

 however, is there. Perhaps the most interesting water plant present is 

 Limnanthemum parvifoUum, only known previously from the transgan- 

 getic peninsula through a gathering in Chittagong by Hooker and 

 Thomson and one in Tavoy by Wallich. The present gathering thus 

 comes in midway between these two and perhaps indicates that the 

 species only requires to be looked for in order to be found elsewhere in 

 lower Burma. Besides the Tamarinds already referred to, there are 

 near the houses of the Burmans some trees of Moringa pterygosperma 

 that have evidently been introduced ; in the same situation there are 

 also a few Coco-nut trees and some Plantains. In the central clearing 

 the telegraph master shewed me what he imagined to be Mangos teen 

 trees belonging to him ; the trees are, however, not trees of Garcinia man- 

 gostana but of Garcinia cornea. He had, beside these, some trees of 

 Citrus medica and G. Aurantium not doing very well ; there were close by 

 also some trees of each of the species Myristica glauca, Artocarpus 

 Chaplaslia and Antiaris toxicaria, all either planted or preserved when the 

 clearing was made ; the present telegraph-master, who has been there 

 many years, says they have been there since before his time. In his plan- 

 tain garden, where he has some of the finest fruit-giving varieties and all 



* In Great Coco Island it is only the red variety of N. Lotus that occurs in its 

 small lake.
