Aboriginal Name. " Yiel-Yiel " of the aborigines of the North Coast o 
New South Wales. " Yill-gill " or " Yil-Yil " are variants of the above. 
Synonyms. Meissr.. in DC. Prod, xiv, 451 ; Agnostus sirmatus A. Cunn., 
in Loud. Hort. Brit. 580 (name only). Slenocarpm Cunninghamii Hook. Bot. 
Mag. t. 4263 (copied into fl. des Serres iii, 189, t. 7) not of R.Br.; Faxt. Mag. 
xiv, i, with a fig. 
This plant is often erroneously sent out as Stenocarpus Cunninghamii by 
nurserymen at the present day, the origin of the name for this particular tree 
being Hooker's description as above, with a beautiful coloured figure. Hooker did 
not know that sixteen years previously (i.e., in 1830) Robert Brown had given the 
name Stenocarpus Cunninghamii to a different species from North-west Australia 
(Vansittart Bay), and which, like the present species, also occurs in Northern 
Queensland. 
Leaves. They arc exceedingly variable in shape, often pinnatifid and 
sometimes a foot long. Mr. Sydney W. Jackson sent mo some as large from Atherton 
in Northern Queensland, from the play-ground of the " Tooth-billed Bower-bird." 
Flowers. A bunch of flowers of the atove, put in a vase and placed 
indoors, has been found to kill flies in large numbers (W. Baeuerlen). 
The arrangement of the flowers affords a good example of what is known as 
an umbel, i.e., when the individual flowers spring from a common point, like the 
ribs of an umbrella. The umbels of flowers are about 3 inches in diameter. They 
are so remarkable as to lend themselves, in a remarkable manner, to the work of the 
designer. 
The following paper is worthy of reference : Dott. El. Tassi : Le Froteaccae, 
in specie dello Stenocarpus sinuatus, Endl : (Studio anatomo-morfologico com- 
parative.) (Bull. Lab. ed Orlo Botanico di Siena, Italia.) Anno 1, Ease. 2-3, 
p. 67, and also p. 80 (189S). A valuable paper. The following plates refer to 
Stenocarpus sinuatm: 1, 2, 3, 4, 5, 6, 7, 8, 9 (partly). 
Timber. The wood pale-coloured or whitish, nicely marked, and admits 
of a good polish. Its medullary rays render it an ornamental timber ; it is close 
grained, moderately hard, and durable, and is used for staves and veneers, and is 
suitable for cabinet-work. 
In Northern Queensland it is in places sufficiently abundant to be used for 
general building purposes, palings, &c. 
Size. It attains a size of 100 feet, with a stem diameter of 3 or 4 feet. 
Habitat. It is recorded in the Flora Australiensis from : 
Queensland. Brisbane River, Moreton Bay (A. Cunningham, W. Hill) ; 
Araucaria Ranges (Leichhardt) ; Queensland Woods, London Exhibition, 1862 (W. 
Hill, n. 17).
