(F.v.M., in B.Fl, iii, 243.) Apple of Victoria.

Systematic. - A large tree, with a red, stringy bark, and a reddish-coloured, worthless timber, similar to that of E. cinerea, F.v.M., and with glaucous, terete branchlets, and glaucous inflorescence. Abnormal leaves glaucous, ovate acuminate, cordate, sessile, opposite, rarely lanceolate, variable in size, the larger ones about 6 inches long and 4 inches wide, and having a very pronounced venation, the marginal vein being removed from the edge; the smaller leaves are much finer in texture. Leaves of mature trees lanceolate, generally under 6 inches long, and varying in breadth, occasionally opposite, same colour on both sides; venation distinct, lateral veins oblique, spreading, intramarginal one removed from the edge. Peduncles axillary, flattened, about 3 lines long, with generally seven or more almost sessile flowers in the head. Calyx tube conical, under 2 lines in diameter; operculum conical, acute, slightly depressed below the apex, or hemispherical and acuminate.

Fruit. - Sessile, turbinate, bell-shaped to hemispherical, occasionally angular at the base; rim thick; valves exserted, sometimes prominently so, when they are acute; about 3 lines in diameter.

These fruits have often a strong resemblance to E. viminalis, but rather smaller.

Habitat. - This is quite a Victorian species, occurring more particularly at Black Flat, Oakleigh, Kingwood.

REMARKS. This is a good species, and quite distinct form "Argyle Apple" (E. cinerea, F.V.M.), which has a similar bark and timber and which characteristics often led Baron von Mueller to express a doubt whether the two trees were not one and the same species (vide "Eucalyptographia" under E. pulverulenta). The two differ distinctly in foliage and fruits. It has little or no affinity with E . Bridgesiana Which tree has a pale-coloured timber, and a "Box" bark and hemispherical fruits. This latter speecies was, by Baron von Mueller, working on herbarium material, confounded with the "Victorian Apple" (E'. Stuartiana), but his frequent reference to the stringy-bark and red-coloured timber of "Argyle Apple" (E. cinerea) shows conclusively that E. Bridgesiana could hardly have been known to him in the field. A. W. Howitt's E. pulverulenta, var. laneeolata, we regard as an aberrant form of E. Stuartiana, in which the lanceolate form of leaf is less, predominant although cordate leaves also occur on mature trees along with flowers and fruits in the axils. The timber, bark, and inflorescence almost identical with the type E. Stuartiana, It has little connection with the lanceolate form of the "Argyle Apple" (E. cinerea F.v.M.) \v South Wales, as that species has consistently three Bowers in the axils, whilst Howitt's tree has almost uniformly seven a fact that appears to have been overlooked by those who have aynonymised it with the " Argyle

Apple " (E. cinerea, F.V.M.). Dr. Howitt who knew both trees well in the Held, and discusseil them with the late Baron von Mueller, was in accord with us in our classification of E'. Stuartiana and E;. Hridgesiana.

ESSENTIAL OIL. - We are indebted to Dr. A. W. Howitt, F.G.S., for the material of this species for distillation.

The leaves and terminal branchlets had been collected as for commercal distillation, and were sent from Melbourne, Victoria, in April, 1898. The yield of oil was 0.4 per cent. The crude oil was red in colour, and had an odour resembling the cineol-pinene oils generally. Phellandrene could not be detected, but pinene was present. The amount of ester was somewhat large, resembling in this respect the oils obtained from E. cinerea and allied species. The oil was rich in cineol, and a determination by the phosphoric acid method (O.M.) gave 53 per cent. of that constituent in the crude oil. The specific gravity of the crude oil = 0.916; and optical rotation aD + 4.8°; refractive index at 200 = 1.4652. The saponification number for the esters and free acid was 14.2. The crude oil was soluble in 1 1/4 volumes 70 per cent. alcohol.
