pi’esent is, as in the Andamans in such situations, the common A. Lotus 
and not, as in the Great Coco, the red-flowered variety. On the banks 
and extending into the water are considerable beds of Scirpus suhulatus 
which does not occur in the other lake. Here on the other hand there 
is neither Polygonum nor Hygrophila present. 
Beyond the coco-nuts the vegetable products of the island can 
hardly be very highly assessed. Miniipsops Uttoralis (Andamanese 
Bullet-wood) is common and so is Lagerstrcemia hypoleuca (Anda¬ 
manese Pyen-ma) ; Ptercarpus indicus (Padouk) is rare however; and 
even of second- or third-rate timber trees such as Liospyros Kurzii (Zebra- 
wood) ; Bipterocarpus sp. (Wood-oil trees) ; Heritiera (Sundri) ; there is 
no great quantity ; the only bamboo found {Bendrocalamus strictus var ?) 
is not very valuable and is not abundant; while the only abundant natural 
grass {Andropogon contortus) is so uninviting that the cattle on the 
island prefer eating Pandanus leaves to grazing it. 
In the subjoined list of the species obtained during the two visits 
(which must not, however, be considered complete, though it may safely 
be assumed to be representative of the vegetation of the islands), it will 
be seen that a number of species are undetermined. As a matter of fact 
they are probably mostly species hitherto undescribed, but owing to the 
shortness of time at the writer’s disposal, and owing to both the visits 
being at the same season of the year, it was impossible to obtain com¬ 
plete material of these, and it has therefore been impossible to prepare for 
them specific descriptions. In some cases roots or seeds of these have 
been brought to Calcutta and are now in cultivation there, so that their 
identification will, it is hoped, only be a matter of time. 
In pi’esenting this list the writer wishes to acknowledge much kind 
assistance received by him in its preparation ; as regards Phanerogams, 
from his friends Mr. W. B, Hemsley, p. e. s., who has kindly com¬ 
pared a number of the more critical specimens at Ke^v ; Mr. J. F Duthie, 
F. L. s., who kindly assisted him in naming the grasses, and Mr. J. S. 
Gamble, p. L. s., who examined the solitary bamboo; and as regards 
Cryptogams, from Dr. G. King, p. r. s., who kindly assisted him in 
determining the Ferns; Mr. G. Massee, p. l. s , who, through the good 
oflfices of Mr. Hemsley, kindly named the Fungi and supplied the des¬ 
cription of a new species of Xylaria; and Mr. G. R. Milne Murray, 
p. L. s., who, through the intervention of Dr. King, most kindly examined 
the Algce. 
The list IS followed by an analysis indicating its systematic, its 
physical, and its phytogeographic nature.
