It is commonly seen flowering and fruiting as a small straggling shrub. Tho 

 lato Mr. Luehmann wrote to me : — 



" Near Bacchus Marsh, Victoria, where Baron yon Mueller found it, I saw 

 E. leucoxylon freely flowering and fruiting at a height of 4 to 6 feet on very poor 

 shingly ground." 



The late Dr. A. W. Howitt called E. leucoxylon '•' White Ironhark " (because 

 of its pale timber) or " Blue Gum," and gave its aboriginal name as " Yandert." 



Note the glands on the filaments (sec figs, le, If, pi. 56). Mueller first 

 drew attention to this (sec his figure in " Eucalyptographia "). I have only seen 

 this glandular appearance on E. leucoxylon and E. Caleyi, and it should be looked 

 for on other species. Diels figures it on his E. Forvestiana. 



SYNONYM. 



E. gracilipes, Naudin. 



I have already explained how this species arose, and have referred to it briefly 

 in Proc. Linn. *Soc. N.S.W., xxviii, 89G (1903). 



I give a translation of Naudin's original description of his species, as I find 

 that it is not readily accessible to Australians : — 



Tree very close to E. leucoxylon, from which it differs especially in its juvenile state, which attaches 

 it to the Inform section. In this early stage, the leaves, which are very much broader and shorter than 

 when full grown, are opposite, sessile, oval-oblong, from G- 8 cm. long, and from 3-4 broad. When full 

 grown they are, as in the generality of species, petiolate, alternate, narrow-lanceolate, pointed, from 

 10-12 cm. long, and 1-1 i cm. broad. The inflorescence closely recalls that of E. leucoxylon. It consists 

 of axillary umbels, generally three flowered, but often with five and more rarely seven flowers ; pendulous, 

 because of the length of the common peduncle and of the pedicels af the flowers. The flower-buds are 

 ovoid, with their opercula almost the length of the calyx-tube, a little eularged at the base, and terminated 

 by a sharp or curved point. The fruit, which is of the size of a pea, is ovoid-truncate, and its capsule, 

 3-1 celled, is deeply enclosed. 



I do not know from what part of Australia this tree is originally a native, having found it without 

 locality in the garden of M. Hubcr, at Hyeres. 



My trees are about five years old, 3 metres high, with slender trunk, which becomes smooth and 

 almost white after the shedding of its first bark. The general tint of the foliage is much lighter than that 

 of E. leucoxylon. (2nd Mem., p. 37.) 



Varieties. 



This is a variable species, and many varieties have been named in connection 

 with it. In my view, nearly all of I hem fall to the ground. So far as I know, the 

 named forms are as follows : — 



1. Var. pluriftora, F.y.M. (Miq. in Ned. Kruid. Arch.,vr ) 127 [1856]). 



This is E. olorctta, Bchr, var. calcicultrlr, Miqucl. See p. 29, Vol. II, of the 

 present work,
