Variety integrifolia , Maiden and Betche. 
In Proc. Linn. Soc., N.S.W., 1896, p. 624, Mr. Betche and I described a 
Macadamia under the name M. integrifolia, from Camden Haven, N.S.W. It was 
stated that it is readily distinguished from M. ternifolia by the petiolate entire 
leaves, rather small fruits, and less hairy flowers and inflorescence. Although the 
tree looks sufficiently different from M. ternifolia, one of us has since examined the 
material in the Melbourne Herbarium, and we have come to the conclusion {Proc. 
Linn. Soc., N.S.W., 1899, p. 150) that it can only be regarded as a variety. We 
found all degrees of transition between the two extreme forms, and have been 
forced to the conclusion that it is merely another instance of the great variability of 
the Proteaceous trees from which the Order derives its name. 
Mr. F. M. Bailey {Queensland Flora, p. 1330) says :— 
There are probably three forms of this species, viz., the typical; another with nuts, only half the 
size of the typical. These nuts I have only received from the Pine River, but hitherto I have never 
received specimens of other parts of the tree or shrub. The third seems only to differ from the typical 
form in the leaves being usually more lanceolate, and in habit. It grows in the Maroochie scrubs, and 
instead of a single stem several arise from a spreading rhizome-like base some little distance from each 
other. These attain the height of 15 or more feet, and are said after fruiting to die early ; the leaves are 
of a thinner texture than the typical form, but the nut differs in nothing from the common form. 
Botanical Name. — Macadamia, in honor of John Macadam, M.D., of 
Victoria, Hon. Sec. of the Philosophical Institute of Victoria at the time the plant 
was described before that body ; ternifolia, Latin, terni (three together), the leaves 
being commonly in threes. They, however, sometimes form a whorl of four, and in 
very rare instances, even five. 
Vernacular Name. —The name Queensland Nut is in universal use, owing 
to the tree having been first discovered in the northern State. It was subsequently 
found in New South Wales also, but the first name is firmly fixed, and is likely to 
remain so. 
Aboriginal Name.— “ Kindal Kindal ” of the aborigines, who knew the 
tree well. 
Synonym. — Helicia ternifolia, F. Muell., Fragm. ii, 91; vi, 191. 
Leaves. —The variation in the number of leaves in the whorl and of the 
margin has already been alluded to. 
In Bull, del Laboratorio ed Orto Botanico di Siena . Fasc., 2-3 (1898), Prof. 
Tassi describes, and at Tav. xii figures, a new fungus {Macrophoma Macadamia, 
n. sp.) on this tree. 
. Frilit.—This tree bears an edible nut of excellent flavour, relished both 
by aborigines and Europeans. As it forms a nutritious article of food to the former, 
timber-getters are not allowed to fell these trees. It is well worth extensive culti¬ 
vation, for the nuts are always eagerly bought. Is said to take seven years from 
the time the nuts are planted before the tree reaches maturity and bears fruit.
