A yellow villarsia shared with nympheea the ponds, and several 
yellow ipomaeas twined round the trees at the very edge of the 
water. » 
Various species of melaleuca took the place of the eucalyptus, 
which disappeared, with the exception of the box, as we 
approached the coast. One species of pandanus was growing on 
a light sandy soil in the open bloodwood forest, and formed broad 
belts at the outside of the forest land along the levels of the 
Alligator Rivers. Another species crowded round the running 
creeks in an almost impassable jungle on the west side of the 
Gulf. The nonda-tree, which belongs in all probability to the 
rhamnacete, was a fine shady spreading tree, laden with yellow 
plums, between the Lynd and the Van Diemen. The raspberry- 
jam tree covered the slopes of the salt-water rivers and the valleys 
of those creeks which intersected the plains at the head ot the 
gulf. The stringy-bark tree re-appeared on the sandy flats of 
the Upper Lynd ; but on the west coast of the gulf it formed the 
principal part of a scrubby forest. Over Arnheim’s Land and the 
north-west coast towards Port Essington, the orange-blossomed 
eucalyptus, a leguminous tree with a dark fissured bark, and the 
Livistona-palm had an equal share in the composition of the 
forest. Inga moniliformis was first seen at a tributary creek of 
the Mitchell; but was afterwards, with a broad-leaved tcrminalia, 
a white gum, and the mangrove myrtle (stravadium), a constant 
companion of creeks and waterholes. A species of bossieea, with 
flat stem, composed principally the scrub of the west coast of the 
gulf, and it was here we observed grevillea pungens with thirsi of 
scarlet flowers. A noble cycas-tree, which frequently attained the 
height of fifty feet, formed large groves on Cycas Creek and the 
Robinson; but disappeared as we left this river, and was not 
observed again until we arrived at Port Essington, where two or 
three small trees are growing near Victoria. 
The Corypha-palm, which we had observed on Palm-tree 
Creek, and under Expedition Range, was found again on the 
Mitchell, at Beames’s Brook, and on the South Alligator River. 
Very low specimens of seaforthia grew on Arnheim’s Land, but
