There are 84 genera common to Europe & marked x = extra-tropical or chiefly so. – Could there be any (certainly few I presume) genera added to these, equally extratropical, but found only in Asia or North America, for they would in fact come into same category.
Haloragis, Microtis, &c see list [illeg]
These 84 genera (or more, if these are N. Asiatic or N. American genera) contain how many species in Australia? [insertion:] I have added the numbers
And of such species in these 84 genera, how many are endemic to Australia & how many common to Europe (& N. Asia or N. America)?
[insertion:] I have added the numbers (approx) of each genus
[insertion:] These are in the European lists of species!
This would be very interesting to me, as it would show how many species had probably been there manufactured since Glacial Epoch.
It would be interesting to see whether same genera or orders have [few words illeg] & Australia. What does [illeg] India mean
Is not the extra-tropical resemblance of Cape & SW Australia due to Glacial epoch as shown by character of Abyssinian Flora & on W. African south?

Of the species included in the 84 genera how many are annual? Is it a large proportion compared to the proportion in Europe? This bears on passage of the Tropics: but perhaps it would be best to take only the species which are terrestrial.
A great proportion of both are herbaceous weeds, but few are true annuals. Consult Loudon in which all will be found
In some list of species common to (Victoria & Tasmania) & Europe. Are those marked * lowland Indian plants; I suppose so. It would greatly add to interest of list to me, if some would append [symbol] for annual & some mark for aquatic & sub-aquatic. Was it not very difficult to eliminate the introduced plants? yes mostly
No I have very few dubious & have marked all that are possibly introduced
