48 A BOTANICAL EXCURSION TO PULAU ADANG. 
white spadix and a green spathe. Pleopeltis phymatodes was very 
abundant. We did “not find this common fern at all in the rest 
of the Pulau Adang group of islands. It was intensely hot and we 
returned to the southern shore, finding abundance of fruits of 
Gyrocarpus Jacquinii, a tree not common further south. 
After collecting a little along the shore and bathing we return- 
ed to the boat and left for Kwala Malacca in the Lankawi islands, 
arriving off Burau bay in the evening where we anchored for the 
night. Next day we landed and ws alked up to the 7 Wells, Telayah 
Tujoh ; a good track leads to this spot. On the way | collected a 
good many plants of interest, H/ettariopsis pubescens, Pteris cretica 
the erey- -leaved variety, a pretty new species of Phyllanthus of the 
Reidia section Ph., and found Mesua ferrea in flower. 
The seven wells are formed by a stream which descending 
from the hill behind spreads over a wide space of smooth grey rock. 
In this are excavated by the water a number of basins, some of 
which are deep enough to bathe in, and these are the seven wells. 
The stream then falls over a precipitous slope. The spot is a 
favourite one for Malay picnics, and the water is supposed to have 
valuable properties and the men drank some and took bottles home 
with them, which made them all ill as the water is obviously not 
fit to drink. The view from this stream is very fine. The rugged 
range of Gunong Chinchang rises on one side, and on the other are 
hills clad in dense forest, forming an amphitheatre at the end of 
which is the deep blue sea. The stream at this point is about 1,000 
feet above sea level. 
We returned from here to Penang and then to Kuala Lumpur 
and so home. 
The most noticeable part about the flora as a whole was its 
difference from that of the Lankawi islands especially in the pre- 
ponderance of Malayan as opposed to southern Siamese plants. 
Naturally the two groups of islands being so near, there were a 
number of plants characteristic of the south Siamese flora as laid 
down 1n a previous paper, but there were also a number of Malay 
Peninsula forms, such as Agelaea, Urophyllum, Lasianthus, some 
of the Dipterocarpeae and Anonaceae, etc. The flora suggests 
rather an affinity with the Pulau Song-Song group of islands off 
the Kedah coast which contains nothing or little of the south 
Siamese flora. It seems too to have relations with the Andaman 
islands which are not at all connected with the south Siamese plants 
but which have a Malayan flora. On the seashores of the Adang 
group we have a series of plants which are absent almost entirely 
from the Malay Peninsula, One barbonica, Tournefortia argen- 
tea, [ernandia peltata, and Gyrocarpus. ‘The Ochrosia is only 
known as native in the Peninsula from a specimen said to be 
collected in Singapore by Wallich. It has never been seen here 
again. ‘Tournefortia argentea has not been seen in our region at 
all, but occurs in St. Barbe isle south of Singapore and along the 
Malay isles to the Pacific. Hernandia peltata is at least rare on
