764 president's address. 



Our results may, for many years, prevent us from affording 

 satisfactory information in regard to a number of these points^ 

 but they are ideals, and should be striven after. 



I show you to-night a " curving boundary " of one of our impor- 

 tant species. This idea of graphic representation of range of species 

 occurred to me many years ago, and I have had it in limited use 

 for two or three years. It may proceed simultaneously with the 

 main botanical map, and is, in fact, siipplementar}^ to it.

EASTERN COUNTIES. 



El. Mo7iaro County. 



This consists of the well known tableland of the Monaro, and 

 is bounded on the east by the Dividing Range, on the south by 

 the Victorian Border, on the west by the Snowy Range (Mt. 

 Kosciusko to Kiandra), and on the north by the Micelago Creek. 

 It comprises the counties of Wallace, Wellesley, and Beresford.

While this district is commonly known as the '• South Coast, "^

 It comprises the counties of Auckland, Dampier, St. Vincent, and 

 Cg,mden (exclusive of Illawarra and of that portion west and 

 north-west of the railway line between Marulan and Mittagong). 



ES. Illawarra County. 



For botanical purposes I would define its boundaries as— east,, 

 the ocean; west, the Illawarra Range; north, the Cordeaux River; 

 and south, the Coast Range. 



As thus defined the Illawarra is a fairly definite botanical area. 

 The South Coast and North Coast Counties include many portions 

 of brush country very similar to that of the Illawarra. Different 

 people, however, define the Illawarra differently. 



McFarland in his "Illawarra and Monaro" (Sydney, 1872), 

 defines the Illawarra as extending from Bulli to the Shoalhaven, 

 and lying between the Pacific and the Coast Range; it is about
