4 or 6 in through, and as it suckers from the surface roots very 
vigorously, soon forms dense plantations in which nothing else 
can tegetate. The roots are extremely tough and are covered 
v, ith a yellowish hark, and when cut and brought close to the sur- 
face soon push out a crowd of suckers from betiveeu tlie bark and

It IS a very secondary tannin producer— a New South Wales 
specimen only yielding Irom 2 to G per cent, with about 14 per 
cent, of extract , the bark is very fibrous and when passed 
hrough die mill appears as chopped grass. The other Queens- 
an \aiiety, Hophont, also yields a small supply of tannic acid, 
IS used 111 preparing only light skins, and is valued at about 
dOs. a ton in Queensland. The branches are very slightly 
flattened the. young shoots reddish, with alternate phyllodia 
4-8 in. long, straight or falcate, incurved only at the tip, 
apering giadually at both ends, darli green, with a small dark 
g and near the base on the upper margin. When 4 or 6 in. 
ong they are usually from h to over an inch wide. Sometimes, 
loweter, on young plants they reach 8 ins. in length and less 
Pi'iflcipal nerves and numerous
