NOTES ON THE RUTACE^ OF THE AUSTRALIAN 



ALPS.

The remarks of Dr. Woolls on the varieties of Crowea saligna 

 var. exalata, have induced the writer to offer the following notes on 

 the regional distribution of the Rutacese over the Australian Alps. 

 That there should exist on the highest peaks of these mountains 

 representatives of an order whose geographic range extends over the 

 hotter and temperate regions of the world, is perhaps a matter of 

 general interest to students of botany. The whole of the species 

 growing over the Australian Alps are endemic, and are comprised 

 in the tribe Boroniece of the ' Genera Plantarum.' 



Zieria Smith ii, Andr. 



Of seven species of this interesting genus recorded by Baron 

 Mueller in his ' Systematic Census of Australian Plants,' (six of 

 which are found in New South Wales territory), I have identified 

 only one, apparently the var. macrophylla, a Tasmanian form. 

 It is an arborescent species which attains its greatest luxuriance in 

 shaded heads of gullies at sub-alpine stations, generally between 

 2,000 and 4,000 feet above sea level. On the whole, it seems to 

 flourish best over areas where Silurian sediments form the geolo- 

 gical formation, as towards the heads of the Mitchell River and its 

 tributaries in Gippsland, Victoria. At this habitat the flowers 

 have an overpowering but agreeable aroma, while the crushed 

 leaves and bark are exceedingly foetid. The only slight differences 

 which I have observed in the characters of this species, when 

 comparing specimens procured at different altitudes and from
