 Grey Mallee. 



Systematic. A " Mallee" of rather dense growth, or somewhat spreading; 

 usually about 15 feel high, or somewhat higher; stems 2 to 3 inches in diaim u-i 

 rarely growing to tree size oi aboul 25 or 30 feel high, and 6 to i_> inches in 

 diameter. Stems mostly hollow. Branchlets often flattened or quadrangular. 

 Bark grey, somewhal fibrous, or on very old trees even furrowed, approaching 

 thai of an ' Ironbark." Abnormal leaves petiolate, generally Lanceolate in 

 form, sometimes narrower and sometimes broader than the mature ones, 

 opposite, or with a tendency to become so. Normal leaves lanceolate-acuminate, 

 on petioles of about 1 inch long, occasionally falcate, about 6 inches long 

 and up to 1 inch wide, not shuvng; venation spreading, very promineni 

 on both sides, tntramarginal vein removed from the edge. Peduncles 

 axillary, not numerous, flattened and twisted, short, under 6 lines, mostly 3 to 4 

 lines long bearing three to seven short pedicellate or sessile lmds, mostly in 

 threes. Calyx tube hemispherical, 3 lines in diameter ; operculum obtuse, 

 conical, 3 lines long. 



Fruit. -Hemispherical, shortly pedicellate ; rim 

 pyramidal, and sometimes twice the length 

 of the calyx ; valves well exserted ; 3 to 4 

 lines in diameter. 



No other species of fruits appear to have the fades of 

 this one, and so presents no difficulty in identification. 



Habitat. -Near Girilambone, on stony or rocky hills; thence 

 on hills across country to Cbbar; also near 

 Coolabah, New South Wales. 



REMARKS. I In - species is a " Mallee " of the Northern interior oi this State, u here it is found associated 

 with the Green Mallee," I i KM: and a1 times with ! oleosa, F.v.M. The bark is sometimes pei 



right out to the branches, whilst on somi trei i1 i mcoth nearly half-way down Thepet istenl bark is rougher and 



irrowed in the largei trees, making a slight approai h to that of the " Iron barks." ft attains, not its greati -i 



er, >'M the highi i hills amongst the roughesl and rockiest parts. Perhaps 

 the most remarkable pecifii morphological charai a out it is the rim of the fruits, The word " domed " hardly 

 expresses correc tly this feature, for, Tni ito thi valve at the top, it forms, as it wei e, a truncate cone, resting 



hemispherical calyx rhis conformation oi the rim. is noticeable as s l as the stamens begin to fall off, 



and fro , its lull devi lopmeni it gives the appearance to the fruit of a pathological affection 



or a mon trosity. The shape of the fruits, however, i cor tant throughout the extensive range ol thi pecies. 



ESSENTIAL OIL. Leaves and terminal branchlets for distillation were 

 obtained from Girilambone, N.S.W., in January, 1900. The yield of oil was \-- 

 per cent. The crude oil was but slightly coloured, and had an odour resembling 

 those belonging to the cineol pinene class generally. The rectified oil was 

 slightly tinged yellow, a character common to those of this group. The oil may 

 be considered a good one for pharmaceutical purposes, although perhaps a little 

 low in specific gravity in the spring and summer months, and as it contained a 

 very small amount oi high-boiling constituents, the greater portion (95 per cent.) 

 distilled below r.88 C. Pinene wa? the principal terpene, and phellandrene was 

 absenl ; in fact, the oil may be considered to consist very largei} of pinene and 

 1 up ol, and to be rich in the latter constituent. The esters were not pronounced.
