NOTES ON EUCALYPTUS. 453 



of the " Eucalyptographia." If Mueller's plate of a species 

 includes all the points, I have nothing to add to it, but Mr. 

 W. D. Campbell's "rich crimson" (p. 239) specimen (la, 

 plate 77) seemed to possess a character which usefully 

 supplemented Mueller's plate. I may mention that the 

 "rounded" appearance of the filaments as seen in fig. la 

 of Plate 77 (in contradistinction to the "square-cut" and 

 "straight-sided" arrangement) is also seen in the Botanic 

 Gardens, Sydney (cultivated) specimens, in two successive 

 years (May, 1916, 13th August, 1917, the latter date being 

 the date of the first throwing off of the operculum for 1917). 

 Therefore in this species the filaments may be either 

 "straight-cut" or "rounded" as depicted in the Orit. Rev. 

 drawing to which I have referred. 



It is also to be observed that on the filaments pushing off the 

 thick, almost fleshy operculum, the inside of the operculum 

 shows a partial " perforation " at the apex of the operculum, 

 running nearly about half way towards the apex. This 

 tunnel-like process represents a mould of the upper portion 

 of the style and also the stigma. 



Mr. W. Catton Grasby, Perth, usefully supplements my 

 notes on the range of E. macrocarpa: — " It is almost invari- 

 ably found on what we call sand-plains, that is the heath 

 country. I cannot say how far it extends, but I have 

 noticed it on the big sand plains between Wongan HiUs and 

 Bolgart which is north of Toodyay, also on sand plains about 

 seventy miles east of Narrogin as well as east of York 

 where it was evidently first located by Drummond. As 

 you know, these sand plains generally occupy stretches of 

 forest country which occupy depressions. If we take the 

 word Guangan as an equivalent of what we call sand plain 

 Drummond's meaning is perfectly clear."
