288 SCIENTIFIC EXCURSIONS IN NEW HOLLAND. 
those at the base, its pods twisted like a cork-screw. Four 
others are Proteace ; viz.: the Wairum, with very rigid, 
long, and pinnate lobed foliage, the Silver oak (Grevillea 
robusta) ; the Dulabi with lanceolate leaves; and another, of 
which the lower surface is beautifully silvery. In all these 
four species the medullary rays are seen very distinctly 
through the wood. There are several singular trees belong- 
ing to the Malvacee and Sterculiace, one which the colonists 
call Bottle tree, because the trunk swells at about 3-4 feet 
above the ground; its bark is very hard, but the wood soft 
and spongy and full of juice. I have never seen the flower 
of this tree; but its fruit is a capsule, very similar to that of 
Sterculia; the blacks eat the seeds. Another, called Bauni- 
Bauni, forms a very large tree, with thick bark and spongy 
wood; it has very large and long slightly cordate leaves : 
the bark contains a gelatinous transparent substance, which 
adheres to the fingers. A small tree or shrub, with tubular 
scarlet blossoms, grows on the mountains among the rocks. 
On the sea-beach I saw a Malvaceous shrub, or small tree, 
producing foliage similar to a fig and large Hibiscus-like 
flowers: its wood is hard and of a lovely deep, velvetty; 
yellow at the heart. I also found two other species of 
Hibiscus, (H. heterophyllus), which grows almost everywhere 
in the colony, and of which the tenacious bark forms excellent 
natural ropes: this species has white or reddish flowers, the 
base of each petal and the stamens being deep purple. The 
other kind is yellow-flowered, and a third, with foliage re- 
sembling that of a fig, produces pink blossoms. 
Araucaria Cunninghami, the Moreton pine, called by the 
aborigines Gunam, grows in all the bushes by the river and 
the streams ; it attains the stature of a lofty tree, its beautiful 
crown towering above all the rest: another species inhabits 
the brush of the Cerde-Bay River, and is known to the 
natives by the name of Danda-jam. I have heard that still 
another species may be seen near the sea-shore. The 
Cypress-pine (Callitris) is frequent on the sandy beach of the 
coast. 
I am about to send home collections of the plants of the
