west. The presence of forms such as 4. decurrens along 
dry watercourses within the Great Cobar Plain suggests 
that the climate of the interior has become drier in recent

Temora district, and both to Mr. R. H. Cambage and the 
writer, its appearance suggests a new type, probably allied 
to A. decurrens, on account of the peculiarity exhibited 
at times in the seedlings. | 
Appendix. 
The subjoined notes on the earliest leaves of seedling Leguminosee 
are based, mainly, upon the work of Lubbock (46). So far as 
observations have been made upon seedlings of this Order the 
accompanying notes indicate the principal types of the earliest 
leaves belonging to the various tribes enumerated :— 
Papintionace&.—Adult leaves plurijugate, or trifoliolate, some- 
times simple.

Phaseolez.—Simple and opposite. 
Dalbergiez.—Simple or pinnate, opposite. 
CZSALPINIEZ.—Adult leaves bipinnate or pinnate, rarely tripin-
