menus. The eastern side of this ridge had no flat land between it and 
the sea and was rather more open, the tall trees and creepers were much 
as on the west side, with the addition of Argyreia tilicefolia and A. 
HooTceri; large masses of Erycibe paniculata, which is here always a 
heavy climber arid not shrubby; and among the undergrowth with the 
addition of Claoxylon sp.; Oorypha sp.; and near the shore Blachia anda- 
manica; PlucJiea indica; Cnesmone javanica. On bare isolated rocks 
lying well out on the reefs, and never covered completely by the tide, the 
species found are always Fimhristylis sp. ; Cyperus pennatus; and Boer- 
haavia repens. The same species also occur on bare rocky patches of the 
coast all round the island but especially on the west coast. Other 
species associated with these in such situations are Besmodiuni polycar- 
pon; D. triquetrum; Blumea virens; Vernonia diver gens; V. cinerea • 
Pluchea indica, etc. 
The isthmus uniting the outlying peninsula at the north-east corner 
with the main island has, mixed with the coco-nut trees occurring there, 
a sparse forest of Mimusops and Bipterocarpus, with an undergrowth 
towards the north coast almost exclusively of Macaranga Tanarius, to- 
wards the south almost entirely of Bodoncea viscosa, though here and 
there on hummocks of soil as opposed to sand, are other trees, like 
Oroxylum indicum ; Heterophragma adenophyllum, etc. Among the her¬ 
baceous species here the most noteworthy is Artisomeles ovata, the only 
Labiate on the islands, which is, however, at this particular spot, very 
plentiful. On the coast of the north-east peninsula Physalis minima 
is a common species, it occurs, however, in similar situations here and 
there on both the Great and the Little Coco; on the slope above 
Strobilanthes pJtyllostachyus is gregarious and plentiful, as it likewise is 
at the north end of Little Coco in a similar situation. 
As an example of the vegetation of level ground, where the soil is 
shingle instead of sand, the north end of Jerry island may be described. 
Here on the beach is a dense thicket of Pemphis acidula ; behind this, 
a few examples of Pandanus odoratissimus ; many Scoevola Kcenigii ; some 
Tournefortia argentea and Sophora tomentosa bushes ; many coco-nut trees- 
much Ccesalpinia Bonducella. Behind this sea-fence the shingle is cover¬ 
ed with a mass of Ipomcea biloba, a striking contrast to what occurs at 
the north-east corner of the island where the shingle has 1 . denticulata 
only. The trees on this shingle are Terminalia Gatappa, Cocos nucifera, 
Ardisia humilis, Ixora brunnescens, Guettarda speciosa, Macaranga Tana- 
rius, Mimusops littoralis, Gyrocarpus Jacquinii, Hernandia peltata. Be¬ 
sides the Ipomoea the only herbaceous vegetation consisted of a few 
fruiting Amorphophalli; the tubers of these brought to Calcutta have 
since sent up bulbiferous leaves that shew the species to be nearly
