192 A RESEARCH ON THE EUCALYPTS OF TASMANIA 



Normal leaves petiolate, lanceolate, sometiines falcate up 

 to 6 inches long, but mostly less than 4 inches, rarely 

 1 inch wide, mostly about i^-inch wide, rather thicker 

 than the "sucker" leaves. Venation not specially pro- 

 minent, lateral veins oblique, intramarginal vein slightly 

 removed from the edge. Peduncles axillary, about ^-inch 

 long, bearing generally under six small flowers, calyx in 

 bud 1 inch long, operculum equal in length, conical 

 acuminate. 



Fruit hemispherical to slightly pyriform, 2 lines in 

 diameter, rim convex, valves slightlv exserted. 



Arbor altitudinem saltem 150' attenens, 4' 

 diemente. Cortex trunco ramisque persistens ; 

 cortex trunci similis Eucalyptis " Box." Folia 

 numerosa, ovata v. lanceolate v. falcata, leviter 

 alternata, petiolata, 3 "-4" longa, infra 1" , 

 lata; vena non clara, obliqua, pauca, longitud- 

 ina dua leviter a margine remota. Peduncu- 

 lus 3-7 floribus. Pedicellus paene 2" longus ; 

 calyx pyriformis ; operculum non calycem 

 excedente, semiglobulosum in rostrum fere 

 conicum, acuminatum. Capsula hemispherica, 

 2 ' lata. Species loco natali '' Black Gum " 

 vocatur. 



Habitat . — Deloraine (R. H. Cambage, F.L.S.). Between 

 Interlaken and Tunbridge, about 3000 feet, and drops 

 down the western slopes to quite a low altitude ; also 

 Strickland (L. G. Irby). 



Timber. — The heartwood is very pale pinky in colour 

 to almost white, with quite an ash appearance and texture. 

 It dresses well with a pleasing sheen, is not heavy, but 

 fairlv hard, fissile, and close-grained. It should prove a 

 splendid substitute for imported Ashes, being quite equal 

 to any Australian Eucalyptus classified as Ash by the local 

 timber world. It is a distinct and important addition to 

 Tasmanian timbers, and might commercially be called 

 *' Tasmanian Ash.*' 



Chemistry. 



Essential Oil. — Material of this species for distillation 

 was collected at Deloraine in June, 1912. Leaves with 

 terminal branchlets were utilised as would be done for 

 commercial purposes. The crude oil when cleared was light 

 olive-brown in colour, and had a terpene odour, together 

 with that of eucalyptol, but with no resemblance to
