Rennie, Cooke, A Finlay, son have examined the resin of X. 
I alcana, F. v. M., a South Australian species. There are two forms 
ci this. The resin of the common form is red, but that of a form 
from Kangaroo Island is yellow. Professor Osborne, of the Uni- 
versity of Adelaide, who examined vegetative material of the latter, 
found it impossible to determine whether it was a distinct species 
or whether age or environment might not be the factors determining 
the differences from the normal form. It was found that paeonol 
occurred in larger quantities in the yellow than in the red. 
The occurrence of the two resins in South Australia is of par- 
ticular interest, as there are two forms of resin obtained from the 
species hitherto known as X. Preissii. The common form in the 
lulls round Perth lias a red resin, but a darker resin is obtained 
from a form which in a previous paper* was separated as a distinct 
species under the name Xanthorriinea reflexa. ' No analyses of this 
have yet been published. 
A. Preissii is a species typical of the Darling, Warren and 
Stirling Districts. X. refit. m is more typical of the Avon District, 
though it penetrates West amongst the other species in isolated 
patches. Its floral characters are not well marked from those of 
the previously described species, but its vegetative characters are 
very distinct. The reflexed leaf bases with their darker resin are an 
important point. The leaves arc more square in section and tougher. 
The leaves in A. Preissii form a large globular tuft; in X. reflexa, 
they are more bluish and form a funnel shaped tuft at the top and
