H.ABIT.\T. 



As far as can be ascertained this species appears to be confined to the 

 northern part of the Northern Territory and the north-west coast of Western 

 AustraHa. This part of Austraha, however, being so httle settled, it is difficult to 

 give anything approaching its true geographical distribution. It occurs plentifully 

 at Port Darwin, according to Mr. Nicholas Holtze, to whom we are indebted for 

 splendid material upon which our botanical and chemical researches were made. 



Mueller's specimen from Arnhem's Land is the same as that from Port 

 Darwin. 



I. HISTORICAL. 



Like Bentham, Mueller, Maiden, and others, we were at first inclined to 

 regard this species as identical with C. arciwsa, A. Cunn. (F. columellaris, F.v.M.), 

 and it was not till after examining herbaria material in Europe, as well as in 

 Australia, that the morphological and histological differences were foimd to be well 

 marked, and these differences were further supported by chemistry. 



The shape of the smaller valves of the cones, the small column, timber, 

 and chemistry, differentiate the species from C.arenosa, A. Cunn., otherwise the 

 fruits resemble somewhat those of C. glauca. 



Whether A. Cunningham's specimen from York Sound, N.W. Coast, and 

 labelled b)' him as C. microcarpa, is identical with this, there is not sufficient data 

 available to enable us to speak with confidence, but we are inclined to think that 

 the two will be found to be the same species. Cunningham's specimen is not 

 in fruit.
