A Botanical Excursion to Pulau Adang. 
Invore Ne RIDLEY, CMG, B.R:S. 
The group of islands of which Pulau Adang is the largest hes 
to the west of the islands of Lankawi and Terutau. It consists of 
3 fairly large island Pulau Adang, Pulau Rawi and Pulau Butong 
and a number of smaller islets. 
The flora of this outlying group had never been investigated 
and I was glad of the opportunity afforded me by Mr, Robinson to 
accompany him there in the “Seabelle,” in April. Leaving Kuala 
Lumpur on April 18th, at 5 p.m., we arrived at Penang next 
morning and starting again in the afternoon reached the islands on 
April 20th., about daybreak. The party consisted of Mr. H. C. 
Robinson, Mr. Seemund, Dr. Hanitsch and myself, with a number 
of zoological collectors and my botanical collector. We brought 
a motor-boat and with the aid of this and the ship’s gig landed 
the collecting party on Pulau Rawi. The only signs of human 
occupation were a few coconut palms and bushes of Justicia Ganda- 
rusa.on the shore. Mr. Robinson and [ started through the woods 
to climb the hill. On the seashore I saw a number of plants of 
Geodorum purpureum but none in flower. The forest proved very 
poor as a collecting ground, consisting of a number of big trees 
rather scattered, and an abundance of climbing lianes, chief of 
which were Agelaea vestita, some Menispermaceae, a chmbing 
bamboo like one seen at Alor Star, Ca/ami and Horthalsias. The 
undergrowth was scanty, a red Jxora (I stricta) and other shrubs, 
Corymbis veratrifolia, and Aspidium polymorphum. The most 
striking tree was the tall Randia exaltata 30 feet or more high and 
9 inches through. It was in flower and we felled one to secure 
specimens. The flowers are white spotted within the tube with 
black. It occurs also in Penang, Burmah and the Andamans. 
Returning to the shore we found the littoral vegetation consisting 
of Vitex pubescens, Terminalia Catappa, Barringtonia SPeCvosi 
(very big trees with the branches curiously ringed), Desmodium 
umbellatum, Stemona Curtisii, ete. The Barringtonias bore great 
quantity of Drynaria and a pale pink flowered Hoya (a . para- 
sitica) grew over the boughs. 
Some of the Dyaks returning from collecting brought Acan- 
thus iNicifolius, Eulophia Keithii and Saceolabium miserum with 
its little inconspicuous yellow and white flowers. 
In the afternoon we went in the motor-boat to a bay in the 
eastern part of the same island. Here the steep rocks were covered 
with scented species of Andropogon which however was flowerless 
and only bore in place of flowers small branches of reduced leaves. 
Plants brought to Singapore and grown there have done the same.
