This bark contains 3.97 per cent. of kino-tannic acid. 
(Mueller and Hoffmann.) Leaves of this species yielded the 
author 29.69 per cent. of extract, and 1.881 per cent. of tannic 
acids. «(Proc K.-S. VGS.W., 23875.p- 267.) 
Victoria and New South Wales.

Leaves of this species, obtained from Brooman, Clyde River,

and 12.069 per cent. of kino-tannic acid. (Proc. R.S., V.S.W.,

69. Eucalyptus rostrata, Schlech/., N.O., Myrtaceze, B.FI., iii., 
240. 
‘“Red Gum.’ (For synonyms and vernacular names, see ‘‘ Timbers.’’) 
Some insect galls from saplings, causing the abortion of leaf- 
buds and flower-buds, have been examined by the author. They 
were more or less perforate, the perfect insect having in most 
cases taken its departure. They were more or less weather-worn 
and pulverulent. The colour yellowish to a dirty yellowish-brown. 
Average diameter about }in. They yielded 70.22 per cent. of 
extract, and 43.4 per cent. of tannic acid. (Proc. &.S., NV.S.W., 
1887, p. 85.) 
Baron Mueller gives the percentage of tannic acid in the bark 
at 8.22. Leaves of this species yielded the author (Joc. cz#., p. 
271), 40.8 per cent. of extract, and 6.62 per cent. of kino-tannic
