servation will show that the analogy between these several organs is more 
remote than Mr, Smith seems to consider 
hat flowers may and do become “ double " by the adventitious develop- 
ment of appendages on their petals by a sort of prolification, or rather by over- 
luxuriant growth (for the term prolification should be strictly confined to those 
cases in which an adventitious bud is formed), I freely admit, though in none 
of the treatises on this subject, so far as I am aware, is this mode of doubling 
alluded to. Mr. Berkeley has seen something of the kind in double Primroses, 
but I believe most of these cases may more correctly be referred to a modifi- 
For the present, at least, I Rin the explanation of the formation of the 
corona of Narcissus, as offered by Lindley, Gay, and Morren, to be nearer to 
the truth than any other yet given, though it is unfortunately not so simple as 
that offered by Mr. Smith, and indeed has led a writer in a contemporary 
(probably by an oversight, though it might serve for a pun) to assert that I con- . 
sider the corona as a series of “ mystified stamens” !

Tree- Vegetation of Australia. 
As one of the Commissioners for the Intercolonial Exhibition, I am called 
upon to prepare an essay on the vegetation of all Australia, especially in refer- 
ence to the resources of the country. As one item of interest, this essay will 
embrace an enumeration of all the trees of Australia, as far as known, so 
nial territory. The tree-vegetation, moreover, impresses on each flora its main 
a, a points largely to its affinity. Thus, no tree of New Zealand 
is identical with Australian eee and thus a greater discrepancy becomes ap- 
parent iiid the flora of New Zealand and Australia than between that of 
India and our continent. If lists ees the trees of any part of the globe could 
be carefully and extensively compiled, undoubtedly very many interesting data, 
not only for phytogeography, but also for industry = SPREE would be ob- 
tained, etc.,

Callitris (Frenela) Parlatorei, F. Muell. 
Th ree was recently discovered by Walter Hill, Esq., the 
Director of the Botanic Garden of Brisbane, at the Darlington Range of Queens- 
land, where it attained a height of fully 60 feet. t approaches 
nearest to Callitris Gunnei and C. fruticosa. It shows the coarse fo 
both, but the partitions of the branchlets are shorter than in C. Gunner From 
e latter, moreover, this new species is recognized by the pointed

e quite of equal length. From Callitris fruticosa it 
differs besides in having no protuberances on the dorsal apex of the valves.
