RANGE. 



It has hitherto only been found in two localities, both in New South Wales, 

 viz. :— On the Sugar Loaf Mountain, near Braidwood, by the original discoverer, and in 

 gullies around Wentworth Falls, Blue Mountains, by the late W. Forsyth. 



In the original description the locality is stated as "On rocky declivities of the 

 Sugar-Loaf Mountain, towards the sources of the Clyde, at elevations between 2,500 

 and 4,000 feet, together with Eriostemon Coxii and Hakea Macrmana." 



The following particulars concerning the habitat, variation in growth, and plant 

 associations of this species were communicated to me by Mr. Baeuerlen at the time of 

 its discovery : — 



Though it ascends as a small weak straggling shrub, nearly to the very top of the Sugar Loaf 

 Mountain (3,800 feet) yet its normal situation is a steep almost vertical and widely broken up mountain 

 side, for there amongst broken cliffs and boulders it attains tree size, reaching a height from 40 to 60 feet, 

 and a diameter from 6-12 inches, the maximum sometimes 15 inches. Intermediate between the top, where 

 it is a weak shrub 4-5 feet in height and hardly 2 inches diameter, and yet heavily laden with fruit, and the 

 steepest region, there is a belt not quite so steep with a layer of soil, where it occurs more in mallee form, 

 sometimes more than a dozen stems springing from one rootstock, in fact in one instance I counted sixteen 

 stems. Farther down amongst the rocks and in the steepest place it grows to tree size, mostly with one 

 stem only, each stem having a considerable rootstock or butt, somewhat in the manner of the Musk (Olearia 

 argyrophylla). Old decayed or burnt out rootstocks of considerable size are plentiful, sometimes from 

 3-4 feet in diameter. From those sometimes spring half a dozen or more trees from 6-9 inches in diameter. 

 It is also noteworthy that though for the first few hundred feet down the mountain E. stricta accompanies 

 the new species, but leaves it when it reaches the steepest and most rocky situation, no other Eucalypt is 

 then associated with it any more until it approaches its lowest elevation, when Messmate (E. amygdalina) 

 and Stringybark (E. ca2yitelktfa) accompany it. I took particular notice of the fact, whether in this very 

 wild situation other species of trees would form those butts, but found no other trees growing there, 

 whether Eucalypts, Acacias or others, forming those butts in the same situation, so that I may assume that 

 they are peculiar to the species and form one of its characteristics. 



For the present I believe that E. Baeuerleni will be found to be confined to this mountain-side and 

 a small narrow hill abutting on this mountain-side, which has one side covered with the species while the 

 other (south-eastern) side has not a single tree on it. 



AFFINITIES. 



1. With E. vimimlis Labill. 



" It recedes mainly from E. viminalis in leaves with thinner venules and more conspicuous oil-dots 

 in the flattened and also often thicker and shorter peduncles, in the angular calyx-tube, in the shape of the 

 operculum, and again in the larger fruits with half -enclosed valves of greater length and narrow rim." 

 (Original description.) 



E. Baeuerleni is one of those species in which each bud has a sharp rim, showing 

 the junction of the slightly wider calyx-tube and operculum. This indicates a second 

 deciduous operculum to each bud.
