706 ON THE EUCALYPTS OF NEW SOUTH WALES, 



In some cases trees belonging to this species have fruits in dense 

 heads. In these trees the foHage is coarser and larger than that 

 of var. micrantha usually is; at the same time the fruits, while 

 numerous in the head, have thicker pedicels than those of var. 

 micrantha; as regards size, the fruits are intermediate between 

 the type and its variety. These clustered fruited forms occur on 

 the Blue Mountains and on the Hawkesbury Ranges. 



Range. — The typical species apparently does not extend much 

 l)e3^ond the Hawkesbury sandstone, and is most abundant not far 

 from Port Jackson, the Hawkesbury and George's River, and the 

 ridges and broken country in the vicinity. While the range is 

 not very precisely defined at present, that of the variety viicrantha 

 is undoubtedly very much more extensive. 



Affinities. — Chiefly with F. Sieberiana, the only species (now 

 that E. virgata has been abolished as a specific name) with which 

 it could readily be confused. 



E. H^MASTOMA var. MICRANTHA. 



Introductory. — In many respects resembling E. hcemasfoma, but 

 the flowers are much smaller and the ti-ee is never rough on the 

 lowest part of the trunk, but always smooth, right to the ground. 



It is one of the most uniform of our Eucalypts, whether 

 occurring on the coast sandy flats, or on the mountain ranges. 



Vernacular names. — •" White Gum " is a very common name. 

 It, however, in one or other of the many districts in which it 

 occurs, usually goes under some name referring to the softness or 

 brittleness of its timber, e.g., "Cabbage Gum," "Snappy Gum," 

 " Brittle Gum," "Brittle Jack." 



£ark. — Smooth, right to the ground. The colour of the bark 

 is usually white, but sometimes, particularly in localities compara- 

 tively remote from the sea, the bark is at certain ' seasons of the 

 3'ear yellowish. Away from the sea, also, the bark appears to 

 have a greater tendency to peel ofi" in patches, giving it more or 

 less a spotted appearance.
