mutabile Lindl., and even Spathoglottis plicata Bl. occurs as 
an epiphyte on a fallen trunk covered with Asplenium Nidus b. 
On the ground are various smaller herbs among which Cyathula 
prostrata (L.) BL, Oplismenus compositus Beauv., Begonia isop- 
tera. Dryand., various terrestrial orchids such as Calanthe Zol- 
lingeri Richb. f., Corymbis veratrifolia Richb. f., Goodyera colorata 
Bl., Macodes petola Lindl., Phajus Tankervilliae Bl., Vrijdagzynea 
spec. This luxuriant domain also produces big ferns such as 
Angiopteris javanica Pr. and Cyathea javanica Bl. The flora of 
this part of the mountain is therefore considerably different 
from that on Krakatau at the corresponding altitude as it dis- 
plays far more various species of plants and is less marked by 
the predominance of certain definite species; in fact the forest 
is already more normal than that of Krakatau. 
April 26th is spent in an excursion to Krakatau and Verlaten 
Eiland, so that on the following morning, 
April 27th we anchor opposite the South-coast of Sebesy. The 
coast of this island facing South is very rocky and rises ab- 
ruptly almost without a break to the highest peak. Narrow 
patches of white beach are noticeable only here and there. 
The swell is very strong on this side; though the waters were 
as smooth as a mirror the ocean swell was so high that we 
could only land at the peril of our lives and had only three 
quarters of an hour in which to botanise. The strip of sands 
where we went ashore was very narrow; it is probably sub- 
merged when the tide is high for there was not a plant on it 
and the slightly higher coast wall was broken up and sapped 
by the sea. Immediately beyond this ridge the ground rises and 
a few hundred feet further on unscaleable precipices rose like 
walls, only the downpouring water had scoured out a shallow 
gulch which was now quite dry. On the raised ledge flourished 
various beach plants such as Acrostichum aureum L., Ischae- 
mum muticum L., and Vigna marina Merr. Close to the coast 
were found especially Barringtonia asiatica Kurz. and Terminalia 
Catappa L., besides Guettarda speciosa L., and Morinda citri-
