Arbor magna saltus, "Yellow Box" vocata; cortie'e aspero, tenui, lamelloso-fibroso ; ligno flavo ad 

 pallido-bruneo ; foliis juvenilibus subtus pallidis, lato-lanceolatis, marginibus undulatis, vena peripherica 

 a margine distincte remota ; venis secundariis e costa media 60-70° orientibus ; foliis maturis mediocriter 

 tenuibus, petiolatis, angusto-lanceolatis, 2 cm. latis, 11 cm. longis, vena peripherica margini approximate, 

 venis secundariis ex costa 40-50° orientibus; inflorescentia paniculata, umbellis 5-floris, pedunculis 

 pedicellisque planis, calycis tubo operculo sequilongo, operculo conoideo, antheris latis paralleliter dehiscenti- 

 bus. 



Fructibus conoideis vel fere hemispherieo, circa 5 mm. diametro, 1 v. 2-angulatis, margine tenui, 

 valvis modo ex orificio exsertis. 



A large forest tree, known locally as " Yellow Box,"' the branchlets somewhat angular. Bark of 

 butt rough, thin, somewhat harsh; may be described as flaky-fibrous; branches smooth, brownish. Timber 

 pale brown when dry (has a yellow tinge when fresh), rather interlocked, somewhat coarse-grained, tough. 



Juvenile leaves thin, paler on the underside, petiolate, broadly lanceolate (2-5 to 3 cm. broad,. 

 5 to 6 cm. long), with undulate margins, the intramarginal vein moderately distant from the edge, the 

 secondary veins making an angle of 60-70° with the midrib. 



Mature leaves moderately thin, petiolate, narrow-lanceolate, somewhat undulate and falcate, 

 tapering towards the apex (2 cm. broad, and about 11 cm. long), the intramarginal vein close to the edge, 

 the secondary veins making an angle of 40-50° with the midrib. 



Inflorescence paniculate, each umbel up to five ra ther small flowers, buds clavate, the peduncle 

 flattened, the pedicels also flattened but shorter, the calyx-tube of the.same length as the operculum, and 

 with at least one distinct ridge, the operculum conoid. Anthers broad, opening in parallel slits, gland at 

 the top and back, filament at base or nearly so. 



Fruits conoid, occasionally almost hemispherical, about 5 mm. in greatest diameter, shiny, the 

 calyx-tube with one or two angles or ridges, the rim thin, the tips of the deltoid valves of the capsule just 

 protruding from the orifice. 



[Mr. Rummery writes : " The timber has every appearance of being durable and strong. The only 

 uses I have seen it put to so far is for slabs for a small hut, and a few girders, but I am of opinion that it 

 is a valuable timber, and in time will be much used for general purposes. It grows to a large size, both 

 in barrel and height, and is usually straight and round .... Timber of a pale yellow colour, and 

 appears to be very durable and strong. I have seen girders squared from this timber, and excepting for 

 a yellow tinge, they were very hard to detect from Grey Ironbark (E. paniculata)."] 



The type is Busby's Flat, near Casino, New South Wales (G. E. Rummery, 

 October, 1921). Named in honour of George Edward Rummery, District Forester 

 of Casino, New South Wales, who not only sent the original specimens, but who has 

 taken a good deal of trouble concerning this interesting tree.
