These are, howevei-, exceptional, aud I follow Mueller (see fio-ure of E. siderophloia 

 in the " Eucalyptographia ") iu looking upon E. sidet^ophloia as having a ratlier 

 long operculum, and the fruit as having well exserted valves. There is no room for 

 a variety rostra ia.^ 



(2.) Var. glauca, Deane and Maiden. Proc. Linn. Soe. N.S.TF., xxiv, 461 

 (1899). 



EoUowing is the original description : — 



This is the glaucous interior form of the species, which goes under the names of " Blue-leaf Ironbark " 

 (in allusion to its glaucous foliage) and " Broad-leaf Ironbark," in allusion to its broad sucker-leaves. 



Its operculum is shorter than that of the normal species, but tlie fruit of var. glauca and of the 

 type are precisely similar except as regards glaucousuess. * 



Duhbo District (H. Deane, Nov., 1892 ; J. V. de Coque and J. L. Boorman, Nov., 1897). This form 

 (from fragments in our possession) will probably be found to have extended range easterly, and more 

 particulary northerly of the Dubbo District. 



" Broad-leaf Ironbark." Mr. J. V. de Coque i-ecently drew attention to this tree, and pointed out 

 that its timber is inferior to that of the other Ironbarks of the Dubbo District. Its timber is of an 

 inferior quality, both as regards " ringing " and " splitting " (cracking), so much so that the timber-getters 

 never cut it except for rails. Mr. Boorman points out that it grows on slightly elevated lands, and is 

 confined to such situations only. When growing in the forest it can readily be noted by its glaucous 

 appearance. 



The " Blue-leaf Ironbark " is not really different from the preceding, although local people point 

 out differences in breadth and glaucousness of leaves. 



It bears a strong superficial resemblance to a specimen in the National Herbarium, Melbourne (in 

 bud only), collected by Charles Stuart in "New England, 1,000-1,500 feet." (New England is never as 

 low as this, so that, if the heights be correct, it must have been collected during an ascent.) His label 

 further states : " 30-40 feet, bark very rugose and deeply furrowed, flowers light yellow ; Mountain 

 Ironbark, No. 128." It bears a label in Mueller's handwriting '^ E. leucoxi/lon," and is probably the var. 

 pallens of Bentham (B.Fl. iii, 210). Ample botanical material is desirable of these aberrant forms; at 

 the same time it is not suggested for a moment that there are not two glaucous species,! the stamens and 

 stigma of E. siderophloia and E. leucoxylon (really sideroxylon) being very different. 



In addition to the localities above enumerated, I have it from — 



" On the sides of hills and out of the crevices of rook, all over the district, not perhaps plentiful, but 

 widely scattered over the hills." A stunted tree, Gungal, near Jlerriwa (J. L. Booi-man). 



SYNONYMS. 



1. E. fibrosa, F.v.M. ~ 



2. E. ornata, Sieb. 



Note on E. persicifolia, DC. 



1. E. fibrosa, F. Muell. in Joura. Linn. Soc. iii, 87, front the Btisbune, is only known from 

 specimens in young bud, in which state I am unable to distinguish them from the var. rostrata of 

 E. siderophloia. F. Mueller, however, designates it as a Stringybark. It may, therefore, prove to be 

 distinct. (B.Fl. iii, 220.) 



• Speaking generally, the var. ij/auca has fruits smaller th.an those of the normal form, Imt this is not a character to 

 bo relied upon. 1 have specimens collected on the Harvey Range, Peak Hill district, by .1. I-. Boonuiin, with fruits just as 

 large as those of the type. 



t Since the above was written, I have described a new glaucous species as /J. l'(Uei/l, and its simil.aritios and 

 dissimilarities to E. siderupliloia, var. ylauea, will be dealt with when speaking of E. Cali'ifi.
