discussion: P . monticola F. Muell. belongs 
in the section Aero stigma. Its author, Baron 
von Mueller, published upon it three times. In 
1865 he published the binomial for it as a 
doubtful species, and gave a casual reference 
to fruit characters. The type locality was 
Rockingham’s Bay, but the authenticating speci- 
men preserved in the Melbourne herbarium, 
collected in 1864 by J. Dallachy, consists of 
one leaf and parts of a staminate inflorescence. 
This is taken to be the holotype. 
His second publication, in 1870, was based 
upon study of a collection from "valle Dal- 
rympli,” also by J. Dallachy. Here, von 
Mueller positively adopted the species and gave 
a good description, including characters of the 
scarlet fruit. 
In 1874 he published on it a third time, 
supplementing the herbage characters, and de- 
scribing the staminate flowers.
