NOTES ON EUCALYPTUS. 489 
Speaking generally, we may say that (b) differs from (a) 
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 urceolate. Form (b) seems 
to be more uniform in character than (a). 
I venture to look upon (b), or the W.A. form, asa variety, 
and therefore suggest the name Yilgarnensis, i.e. EH. 
gracilis var. Yilgarnensis for it, following Diels, see C.R., 
lii, 82. 
At present it seems to me that there is not sufficient 
evidence to keep (a) the N.S.W., V. and S.A. gracilis 
specifically apart from (b) the W.A. form. The W.A. plant 
attains a larger size than I have known the species to 
attain east of the Great Australian Bight, but it would 
appear that this is reasonably explained by assuming that 
the species has its optimum in the Western State. 
The attention of our W.A. and S.A. friends may be © 
invited to the problem, particularly in regard to variation 
in the species in eastern W.A. and western S.A. 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, one to two 
and a half inches long, half to one inch broad, veins numer- 
ous, often distinctly trinerved, the intramarginal vein 
usually distant from the edge; occasionally one or two 
lateral veins almost parallel with the midrib as in the adult 
foliage, the smaller ones at an angle of about 60°, and again 
variously branched; lower petioles short, compressed, the 
upper ones more terete. 
4, H. NORMANTONENSIS n. sp., Maiden and Cambage. 
This proposed species has already been referred to twice 
in this Journ., viz., XLIX, 326-7, in which I looked upon it
