Mora of Narcondam and Barren Island. 
forest, mainly Ficus, but has for its undergrowth quantities of Garyota 
mitis, with dense patches of Pollia Aclisia underneath. 
The ridges between the gorges are tolerably uniform in the nature 
of their vegetation; Premna integrifolia extends a good way up, Morinda 
bracteata is found throughout the island and is as common at the top as 
it is on the coast; Trema amboinensis, Capparis sepiaria, and Acacia con- 
cinna, are common species ; not infreqnent is Callicarpa arhorea, though 
far less common here than on Barren Island. In the gorges patches of 
Macaranga Tanarius, Trema amboinensis, Pipturus velutinus, Boehmeria 
malabarica, as gregarious species, are common, and form, especially in 
the lower part of the hill, the prevalent undergrowth. The trees are 
those already enumerated, but as additional species, may be mentioned 
the following, all obtained in the gorge leading from Anchorage Bay to 
the summit of the peak :— Amoora Bohitulca, Apodytes andamanica. Seme- 
carpus heterophylla, Myristica glauca. Ficus glaberrima —the last mentioned 
a small tree, at about 2000 feet elevation. The climbers not previously 
noted were Anamirta Cocculus, frequent; Antitaxis calocarpa, very com¬ 
mon ; Aristolochia Tagala ; Gouania leptostachya ; Trichosanthes palmata ; 
Anodendron paniculatum; Pischidia nummularia ; Pothos scandens, and 
Strychnos acuminata, at about 1200 feet elevation. The herbaceous 
species not before observed were Blumea myriocephala, only once at about 
1600 feet elevation; Asplenium nidus, seen on trees throughout the ascent; 
Nephrodium terminans, not common below 1000 feet, very frequent above 
that height; Bavallia speluncce, here and there throughout the ascent, 
Polypodium irioides, at about 1800 feet elevation; Polypodium adnascens, 
on trees throughout the island, not common ; Bryum coronatum. 
As the summit is neared, and one passes within the area usually 
moistened by the cloud-cap, the trees are covered with moss (NecJcera 
rugulosai), and bear on their bark quantities of Trichomanes pyxidiferum. 
In other respects the jungle on the top does not differ from that lower 
down, except that, owing to the ridges being of necessity greater in pro¬ 
portion to the gorges than lower down the hill, there is relatively more 
of scrub jungle than one finds below. 
Few Fungi were obtained during the visit: doubtless the season of 
the year was unfavourable. Ho Algoe were found either on the rocks 
or washed up on the beaches. The ocean-drifts consisted almost entire¬ 
ly of fruits or seeds of species that occur on the island; the only excep¬ 
tion noted was a fruit of Heritiera littoralis found at East Bay. 
Barren Island is situated in the Andaman Sea, in Lat. 12° 16' H. 
and Lon. 93° 50' E., 60 miles to the east of Middle Andaman, 74 miles 
south-south-west of Harcondam, 80 miles north-north-east of Flat Bock
