Gramineae. 
Andropogon Schimperi, //ochst. 
Tricholena rosea, WVees. 
Sorghum vulgare, Pers. 
Panicum maximum, 7ayu. 
Eleusine caracana, Pers. 
Eleusine oligostachya, Link. 
Eragrostis elegans, WVees. 
There is, of course, with many of these plants no fear that they 
may be taken as indigenous ; but others—for instance, Hleusine, 
Eragrostis, Panicum, and Andropogon, which are represented in 
numerous species in North Australia—will easily be collected as 
truly indigenous. 
I come now to a few plants which, although truly indigenous 
in North Australia, have been introduced in a cultivated state, 
and have escaped from cultivation. These plants are :—_ 
Corchorus capsularis, Lin. 
Crotolaria juncea, Zin. 
Acacia Farnesiana, Willd. 
Oryza sativa, Lin. 
Sorghum Haleppense, Pers. 
We all know that plants alter much by cultivation, and in 
these cases also there is no mistake possible if the presence of 
introduced plants is once recorded. In conclusion, I will draw 
your attention to the fact that Oryza sativa is found truly wild 
only in Arnheim Land. The same can be said of Phaseolus 
vulgaris, Lin., Dolichos uniflorus, Lam., and Dioscorea sativa, 
Lin. Is, then, Australia the home from where these plants 
have been introduced to India and other countries many 
centuries before our times? or has Australia been connected 
with Asia in prehistoric ages? Geologists tell us that we inhabit 
the remnant of the oldest continent ; flora and fauna contain the 
nearest allies to antediluvian formations. Can it then be 
possible that the beastlike Autochthone Australian has been the 
ancestor of the human family? I must leave it for abler 
thinkers to solve this prahlem.
