334 TRANSACTIONS AND I'liOCKKUINGS OF THE [Sess. r.xvii. 



The order Mvin'ACE.E is represented not only by the 

 arboreous form of the genus Eucalypf/ns, but also by a 

 number of shrubs of the genera Callistemon, Lcptospermum., 

 Bceckea, and others. Of the latter, Callistemon scdignns, var. 

 sieheriana, is met with not only margining the principal 

 streams of 2000 ft., but also ascending to the source 

 runnels intersecting the higher plateaux, where, along with 

 Baxkea gunniana, and dwarfed varieties of Lcptof^permivm 

 and Kunzea, it forms dense undergrowths in the neighbour- 

 hood of Sphagnum beds. 



Among Eucalypts, the species E. stcllulata, E. Gnnnii, 

 and E. jjaucijlora are perhaps the most generally distri- 

 buted at the higher levels, ascendino" to the edge of the 

 snowy plateaux as dwarfed, stunted, and gnarled gum- 

 scrub. In the humid shady slopes at lower elevations up 

 to 4000 ft. lofty forms of E. Glohulus and E. amygdalina 

 are met with, while on the opposite side of the ranges or 

 spurs are several species of stringy bark, as E. macrorhyndia 

 and E. capitellata ; the change is in some places so marked 

 as to exhibit a distinct line of demarcation from the blue 

 and white gums to the stringy barks. 



On the heathy spurs varieties of E. ■p'qjerifa and E. 

 ohliqua are met with, while on damp flats, and on the 

 rich soil of upland gullies, varieties of E. stuartiana are 

 seen. 



The economic value of the Eiicalyptus as timber is so 

 well known that a few remarks on its uses may not be out 

 of place in these notes. 



Notes on the Genus Eucalyptus — Economic Uses. 



The term " gum tree," as applied to the Eucalyptus 

 vegetation, is distinctly erroneous, as the exudation from 

 the hark is a substance called " kino." Some botanists 

 and chemists have further misnamed this exudation by 

 calling it " gum-resin," or " resin." It is by no means an 

 unimportant product, as, in addition to possessing astrin- 

 gent properties, when boiled in an iron saucepan, it forms 

 a good ink, and will stain leather black. The leaves of 

 the blue gum {E. Glohnhis), when pulverised and mixed
