Speaking generally, we may say that (6) differs from («)in the broader and thinner 

 leaves., the longer and more slender peduncles and pedicels, in the less clavate, more 

 cylindroid buds, and also in the uniformly smaller fruits, which have some tendency 

 to be ureeolate. Form (b) seems to be more uniform in character than {a). 



I venture to look upon (6). or the Western Australian form, as a variety, and 

 therefore suggest the name YUgarm • - I.e., E. gracilis var. YUgarnensis for it.. 

 following Diels. See Part III of this work, p. 82. 



At present it seems to me that there is not sufficient evidence to keep (a), the 

 Xew South Wales, Victorian and South Australian gracilis specifically apart from (b). 

 the Western Australian form. They both attain the magnitude of medium-sized trees, 

 and in South Australia it has recently been noted as large, or larger than in the western 

 State. 



The attention of our Western Australian and South Australian friends may be 

 invited to the problem, particularly in regard to variation in the species in eastern 

 Western Australia and western South Australia localities, when the whole matter can 

 be reviewed. 



As regards the juvenile leaves of E. gracilis, the branches are angular; leaves 

 oblong to oblong-lanceolate. 1 to 2\ inches long. \ to 1 inch broad, veins numerous, 

 often distinctly trinerved, the intramarginal vein usually distant from the edge ; occasion- 

 allv one or two lateral veins almost parallel with the midrib as in the adult foliage, the 

 smaller ones at an angle of about 60 degrees, and again variously branched: lower 

 petioles short, compressed, the upper ones more terete. 



In Jour a. W.A. Nat. Hist. Sec. Vol. iii (January, 1911), I contrasted the 

 sucker leaves of what I now look upon as (a), var. YUgarnensis, and (b) E. gracilis, 

 normal form, in the following words : — 



(a) The juvenile leaves [I am describing specimens from Southern Cross. W.A. — 



J.H.M.] are glaucous on both sides, acuminate, tapering to a rather long 

 petiole, lanceolate, the lamina say 3 inches long by f inch broad, the intra- 

 marginal vein at a very considerable distance from the edge, venation spreading, 

 the midrib and intramarginal vein being most conspicuous, giving the leaf a 

 triplinerved appearance. 



(b) So far as I am aware, the juvenile foliage of var. gracilis (E. gracilis) has not 



been previously described. Some from Euston to 3Iildura, Victoria (W. S. 

 Brownscombe) (not far from the type locality) are smaller, and from nearly 

 elliptical to oblong in shape. They do not taper to a point, but are of the 

 same general character as those already described. Then I have juvenile 

 foliage from South Australian localities, collected bv myself, which is narrower 

 in width, but as it is not in as early juvenile stage as that described by me 

 from Western Australia, I invite attention to the matter in order that repre- 

 sentative specimens may be collected.
