parallel with the margin. PediaJs short. Buds : lid hemi- 

 spherical, mucronate. Fruit globose, 3 lines in diameter. 



Bentham's variety rad'iaf.a of E. amygJalina. — Leaves rather 

 broader than type, 3"-4" long. Fruit almost pear-shaped. 



Howitt's form (e) of E. amyydalina. — Z/eai;^^ narrow-lanceolar, 

 falcate. Venation rather indistinct. Marginal vein considerably 

 removed. Lateral veins very longitudinal. Pedicels as long or 

 longer than the bud. Buds : lid small and depressed, with a slight 

 point. Fruit ovate- truncate, with slightly contracted orifice, com- 

 pressed rather narrow rim, and small weak valves. (See his 

 figure, op. cit.). 



The " River White Gum " of l^.^M.— Leaves. The preceding 

 (Howitt's) description applies very well. Very thin leaves. Pedicels 

 rather long, often filiform. Buds nearly hemispherical; Howitt's 

 description applies fairly well to this form. Fruit pilular (globose), 

 very uniform in size (2-2 J lines in diameter), sometimes tending to 

 close at the orifice. (PI. Ivi., fig. 3. ) Often, pale-coloured when dry. 



Above is a comparative statement showing partial and condensed 

 descriptions of A', radiata, Sieb., Bentham's variety radiata, 

 Howitt's form (e) (both of aniyydalina), and River White Gum. 



Sieber gives the breadth of the leaves at from 6-7 lines. Most 

 are of about that breadth, others go up to 9 lines, while we have 

 specimens from the Deua (Moruya) River which has leaves with 

 the exceptional width of 1^ inches (nearly 14 lines!). Sieber 

 gives the length of the leaves at 4 inches. These are too short as 

 far as our River White Gum is concerned, leaves of 6 and 7 inches 

 being common, while those of 5 inches at least are average ones. 

 Sieber says pedicels short; those of the River White Gum are 

 filiform and more than ordinarily long. He further gives the 

 diameter of the fruit as 3 lines; we have never known it in the River 

 White Gum to be quite 2^ lines, really "a difference of some impor- 

 tance when we note how marked a difference in the appearance of 

 a small fruit half a line or more in diameter makes. Nevertheless, 

 after careful consideration of the matter, and examination of a large 

 number of specimens, we are of opinion that Sieber's original 

 ra'iiata was taken from a River White Gum.
