F, Mueller founded the genus Mackinlaya (Fragm. Phytogr. 
Austral. vol. iv., p. 119, t. 29) on specimens of a plant collected at 
Port Molle and Rockingham Bay ; but he had previously described 
(op. cit., vol. ii., pp. 108, 176) this plant under the name of Panaz 
macrosciadeus, from specimens collecte by E. Fitzalan, “ad Portum 
Molle insularum Cumberland Islands,” Queensland, Australia. 
Subsequently Bentham (Flora Austrahensis, vol. iii., p. 383) added 
some additional localities, including Fitzroy Island and Dunk 
Island, from the collections of J. MacGillivray. The specimen in 
question from Fitzroy Island is the genuine Mackinlaya macros- 
ciadea, F. Muell., and it has since been collected in the same island 
by W. Hill; but the Dunk Island plant is quite different, though 
I think it may be referred to the same genus, at least until female 
flowers and fruit are known, both being wanting at present. 
A third species, closely related to the Dunk Island plant, has 
been collected by Mr. G. Versteeg, in Dutch New Guinea. Both 
second place only, and the baccate truit is didymous. _ 
So far as the material goes the previously undescribed species
