Near Inverell and Howell it is frequently or generally found growing in Company with E. deallnta, 
in stony hills, when it has a drooping or " weeping " appearance ; when it occurs on more level country 
it is found with other species, and has a more erect habit. 
A very interesting characteristic of this species is the frequency with which it appears to hybridise 
with White Box (E. hemiphloia var. albens). Trees are to be found in all stages, some showing very distinct 
signs of Ironbark parentage, with only a trace of Box, some Box with a trace of Ironbark, and others BO 
evenly distributed that it is difficult to say which parent predominates. Unfortunately, I only noticed 
this just before I left Inverell, or I should have followed it up. Now I am not in a position to do so.

Trees starting life on Tree-ferns. At p. 30, Part Hi, of the present work, 
under Quintinia Sieberi, I stated that I had mislaid Allan Cunningham's reference to 
the above subject. Here it is : 
A remarkable tree, assuming occasionally (like some Fici of equinoctial countries) a parasitical 
growth, as will appear from the following memorandum, made some years ago in one of its native forests. 
It may be premised, that in the centre of the Blue Mountain chain, directly west from Port Jackson, is a 
remarkable eminence, called Tomah, the height of which, above the level of the ocean, has been ascertained 
to exceed 3,500 feet. Before the axe of the colonist was carried to the base of that mountain, in the great 
chain, viz., prior to 1823, Tomah had its Hanks and summits clothed with a dense vegetation consisting of 
timber trees, loving shade and moisture, laden with orchideous Epiphytes, and borne down heavily by 
gigantic climbers; and beneath them, in deep shade, flourished many a noble specimen of an arborescent 
fern (the Cibotium Billardieri of Kaulfuss), which was not previously known to exist in New South Wales. 
On the side of the mountain was then to be observed a remarkable instance of the disposition of the Quintinia 
to attach itself to other plants by means of cauline roots, that may be worthy notice. 
A large Quintinia (Sieberi, A. DC.) grew near to an aged Cibotium, full 35 feet high, and having 
a distinct trunk in the soil. At about (i feet from the ground, however, the roots which the former had 
thrown out from its stem had got hold of the fern tree, the caudex of which they enveloped by numerous 
folds, so as to present but one trunk of great bulk for upwards of 20 feet. Above this, however, was to bo 
perceived the rough bark of the Quintinia on one side, and the rugged caudex of the fern on the other, the 
trunks of both continuing firmly united, as if grafted into each other, until near their summits, where they 
separated; the Quintinia exhibiting a branching umbrageous head, while the Cibotium spread forth its 
noble tufts of fronds, evidently not in the slightest degree inconvenienced by the embrace of the aerial 
roots of the other, throughout nearly its whole length of caudex.
