sent for identification a large tuber or 'yam' weighing about 10 pounds, stating that 

 similar 'yams' were eaten both by settlers and aborigines. The interior is composed 

 of a whitish substance, the chemical analysis of which shows only 4| per cent of car- 

 bonaceous principles. It tastes very much like a turnip, both in the raw and cooked 

 condition. The color and consistency of the largest specimens resemble those of the 

 common mangel-wurzel." (B. T. Baker.) 



"A vine generally found growing at the foot of and twisting itself around some 

 small tree, and that tree in nine cases out of ten a 'wilga' (Geijera parviflora Lindl.). 

 The top 'yam' of the plant we dug* was 4 inches from the surface, and the deepest 

 that we could find was 21 inches from the surface. We dug up all that we could 

 find, carried them home, and weighed each one separately, 29 'yams' in all. The 

 total weight was 101^ pounds; the heaviest one weighed 12 J pounds." (A. Baddison.)
