434 botany of rylstone and goulburn river districts, 



Malvace^. 



SiDA corrugata, Lindl., var. orbicularis, Benth. Not common; 

 only one plant seen, and that at Murrumbo. This is 

 considered an inland species, with the exception of a 

 specimen obtained at Broadland, on the Hawkesbury 

 River, by Robert Brown; and its presence now on the 

 Goulburn supplies the connecting link with the dry 

 country varieties; October (flower and fruit). 



Abutilon tubulosum, Hook. Bylong; the most southern locality 

 recorded; September. 



Hibiscus Sturtii, Hook. Rare; October (flower and fruit). 



Sterculiace.e. 



Stbrculia diversifolia, G. Don. "Kurrajong." On most of the 

 ridges in the district; November and December. These 

 trees are never cut down, as the foliage is eaten by 

 stock during times of drought. A peculiar fact in con- 

 nection with this species was related to me by Mr. J. 

 Dawson, surveyor for the district. He states that when a 

 living tree of any other species is blazed and marked the 

 sajDwood and bark eventually grow over the marks, and 

 after a few years no trace of the cicatrices can be seen 

 on the tree, but if the bark and alburnum be removed 

 then the whole lettering, &c., is almost as clear as on the 

 day it was oi'iginally cut. I have seen marks after 6 

 inches of the outer growth had been removed as plain 

 and distinct as when chiselled 36 years previously. 

 With the "Kurrajong" (S'. diversifolia) the survey 

 mark is never covered by the alburnum or bark, and 

 always remains on the surface to whatever size the tree 

 may increase in girth. 



RuLlNGiA rugosa, Steetz. Murrumbo; the most easterly habitat 

 recorded; October. 



R. PANNOSA, R. Br, Goulburn River.
