176 AUSTRALIAN NATIVE PLANTS. 
Wight states that the leaves and bark are used as a febrifuge. 
Kanni Loll Dey, in a communication in the Calcutta Exhibition 
Catalogue, says :—“ It is anthelmintic and useful as a collyrium 
(z.e., eye-salve or eye-wash) in ophthalmia. The leaves are 
applied externally to disperse venereal buboes and to relieve pain 
in the joints.” In the Concan, the juice of the young leaves is 
used to kill worms in sores, and the young roots of the white- 
flowered variety are pounded and given with cold milk as an 
aphrodisiac. (Dymock, Materta Medica of Western India.) 
Queensland and Northern Australia. 
58. Erythroxylon australe, #.v.47., N.O., Linex., B.FL, i., 284. 
Erythroxlyum in Muell. Cens. 
Mr. Staiger finds that the leaves do not contain cocaine (the 
well-known alkaloid of Z. Coca), but they contain coca-tannic acid. 
Queensland. 
59. Eucalyptus spp, N.O., Myrtacez. 
It is very difficult to trace to individual species the properties 
ascribed to the genus Eucalyptus. Eucalyptus is a name very 
loosely used by many people, who forget that it comprises (Baron 
Mueller’s census) no less than 134 species, while a fresh one is 
occasionally discovered, and some of these have varieties so well 
marked as to be classed as distinct species by some authors. It 
should not be lost sight of that in this vast genus the properties of 
different species are frequently very different, so that to describe a 
product as simply “ Eucalyptus” is but a bald description, and one 
likely to lead to great confusion. There is some excuse for this, 
however, as Eucalyptus products have only been brought under 
notice during the past quarter of a century, and some allowance 
must be made to outsiders in respect to their references to a genus 
so imperfectly known to Australians themselves. The leaves and 
flowers are usually far removed from the ground (especially the 
flowers), and some apparatus not usually possessed by pedestrians 
must be used to obtain the latter. They are, therefore, compara- 
tively unfamiliar ; this is doubtless partly the reason why they are 
not better known.
