Botanical Name. — Owenia, already explained, Part XIV, p. 90; cepiodora, 
from two Latin words, cepa (caepa), an onion, and odor, a smell or odour. 
Vernacular Name. —“ Onion-Wood ” or “ Bog Onion.” The timber smells 
like decayed onions, though often a newlv-cut plank has a smell resembling water¬ 
melons. 
I have referred to this gradation of “ pleasant ” and “ unpleasant ” odour in 
the same plant at Part XXVI, p. 100. The matter seems worthy of chemical 
investigation. 
Aboriginal Name. —Called “ Ingmunyon ” by the aborigines, “ Bog Onion 
Tree ” by the white settlers (Mueller, in original description). The late Mr. Alfred 
Cadell once sent me specimens of this tree with a message that the aboriginal name 
was “ Boggunyan.” 
I would suggest that neither “Ingmunyon” nor “Boggunyan” are true 
aboriginal names, but were used by the blacks in imitation of the settlers’ names of 
“ Onion ” or “ Bog Onion.” 
Timber. —This is a useful Avood of the cedar class—the wood, in fact, 
being often sold as Bastard Cedar. The name (Onion Wood) is owing to the 
smell of the wood, which is fugitive, and therefore not offensive. Used for the 
same purposes as Cedar. 
Exudations. —This tree exudes a small quantity of a gum, and there is 
also a garlic odour of the foliage resulting from a resinous exudation of the young 
leaves. 
Size. —A medium-sized tree. Average height 100 feet, with a diameter of 
18 inches (Forester Pope). Mr. W. Baeuerlen, then of Tintenbar, gives the height 
at 40 to 60 feet, with a stem-diameter of L foot. 
Habitat. —This tree is confined, so far as is at present knoAvn, to the 
brushes of northern New South Wales and southern Queensland. 
Very little in Clarence River District, but plentiful in the Richmond River District. Found 
scattered about in nearly all the brush forests of the Tweed, wherever the soil is inclined to be rich. 
(Forester Pope.) Tt grows plentifully in Forest Reserve 1,120 (Casino District). 
What the southern limit of this tree is we do not know. It appears to 
become scarce south of the Clarence. It extends into Queensland, Mr. F. M. 
Bailey giving the locality simply as “southern scrubs.”
