The plants of Timor Laut are mostly coral island plants, but 
with some peculiar forms, one species belonging to the flora of 
New Hebrides, and one to that of Australia. Cocoanuts, ferns, 
clerodendra, solanums and malvaceous shrubs occur. The low 
shrubby forest is, in some places, almost impenetrable from its 
spiny character. The largest trees are fig trees (Urostigma) and 
stereulias. The latter is near to the fire-tree of Australia, and 
their crowns of bright scarlet flowers, thrown out in advance of 
the foliage, are very conspicuous. Leguminous trees and myrtles 
abound; there is a pandanus, and a few palms. A green carpet 
of Commelyna hides the rough coral. Artocarpus incisa is not 
uncommon. There are no casuarinas, phyllode-bearing acacias, 
eucalypti or melanolencas. . 
Lieutenant Beresford has ascended the volcano of Ambrym, 
in the New Hebrides. The active crater is about a quarter of a 
mile wide, but there is a large extinct one three or four miles 
across, and other smaller extinct ones. All the hills seem to be 
mere cinder heaps.
