Conservator of Forests). With slightly silvery and golden tips like argyrophylla. 
Also with the scaly appearance on the old valves similar to that observed in A. argyro- 
phylla. This South Australian locality is typical for A. dictyocarpa (brachybotrya 
var. glaucophylld). 
Var. argyrophylla Benth. 
Appears to be peculiar to South Australia, and it has a range from the 
elevated country about Adelaide to the northern part of the State. 
"Blue Bush," Balhannah, 19 miles east of Adelaide (A. L. Thrupp) ; near 
Hamilton (50 miles north of Adelaide) near Kapunda (J. M. Black) ; Hammond,

"Wirrabara, Terowie, Yarcowie, &c. (Walter Gill). 
Propagation. This species (or rather its variety argyrophylla) is much 
sought after for horticultural purposes, because of the golden appearance of its 
young phyllodes. It, however, shows this character best in regions of low rainfall.
