The fruits are sometimes not very dissimilar in shape to those of E. maculata 

 and the small form of E. corymbosa, but the White Ash has no real affinity with either 

 species, as it belongs to a different group entirely. 



4. Yar. triflora, Maiden. 



I have described this variety at page 87, Part xxv, of my "Forest Flora of New 

 South Wales." 



It was originally referred to by Mr. Deane and myself under E. stricta, in Proc. 

 Linn. Soc. N.S.W., 1900, page 108. We received it from Mr. R. H. Cambage from top 

 of Pigeon House Mountain (2,360 feet), near Milton. It is a small tree, a " White Ash." 



Mr. Cambage's note is — " Bark dark, rough at base, then tones off; lower part 

 only a little rough. Not even as rugged as E. pilvlaris." 



Fruits nearly sessile, and in threes, hence the name proposed for this variety. 

 Fruits nearly hemispherical, with a slight tendency to be urceolate. 



The fruits of the arboreal form of stricta from Blackheath are also sessile, and 

 are akin to this form. It would be desirable to ascertain, over large areas of country, 

 to what extent the arboreal form of var. stricta has sessile fruits in threes. 



Speaking generally, the coastal forms of E. virgata are the typical one and its 

 variety obtusifiora, while the mountain forms are those of var. stricta (dwarf or arboreal). 



At first sight E. virgata, Sieb., with its broad, flat horizontal fruit rim, E. obtusi- 

 flora, DC, with its blunt operculum, and E. stricta, DC, with its sunk fruit rim and 

 somewhat urceolate-shaped fruit, are distinct enough in appearance, but when one 

 examines a large series it is evident that we have no constant character to separate 

 them. 



Some specimens, e.g., from the Southern Mountain ranges and South Coast, will 

 not fall under any of the above typical forms. I find myself at different times arranging 

 specimens from the same district, and possibly from the same tree, under the three 

 species or varieties referred to, with good reason in each case. 



Specimens from Sugarloaf Mountain, near Braidwood, for example, would 

 certainly be placed under var. stricta if they stood alone, but the fruits in the broadish 

 rim of some of them show transit to E. virgata (typical). 



From many other localities instances of the unstable character of the forms of 

 this protean species could be cited. 



The confusion between E. stricta, Sieb., and E. cneorifolia, DC. 



I have carefully examined many flowering specimens of E. virgata, and its 

 varieties obtusiflora and stricta, and all have reniform anthers. The anther of E. stricta, 

 as figured in the " Eucalyptographia " (E. stricta plate, No. 5), is also reniform, and 

 is doubtless correct.
