QuEENSLAND. Dunk Island, Rockingham Bay, June 5th, 
1848, John Macgillivray, 269. 
Macgillivray’s 2698, from Fitzroy Island, a degree farther 
north, is M. macrosciadea, F. Muell. Both species occur in the 
Rockingham Bay district. 
There is some uncertainty about the size, habit and duration of 
the plants included here under the genus Mackinlaya. Mueller 
gives no dimensions in his original description of Panax macro- 
sciadea, nor in his definition of the genus Mackinlaya, but in his 
“Essay on the Plants of the Burdekin Expedition,” he mentions 
it as a tree 20 to 30 feet high. Bailey, Queensland Flora, part 2, 
p. 730, describes it as a slender shrub or small tree, and Hill’s label 
records it as a slender shrub, In Macgillivray’s manuscript list 
at Kew of his botanical collections his n. 269 (M. confusa, Hemsl.) 
is defined as a “large herb. plant with 5-digitate leaves.” Versteeg 
notes M. amplifolia, Hemsl., as a tree 3 metres high. It is robable 
that the stem or trunk, as in so many other relatively small 
members of the Araliaceae, is unbranched at the base.
