Following is the description : — 



" Ironbark " altitudiuem 30-10' attinens, trunco 2' diametro; ligno rubro; ramis patentibus, foliis 

 inflorescentiaqne glaucis; foliis juvenilibus tcnuibus petiolatis, ovatis, circiter 8 cm. longis, minus 5 cm. 

 latis: Ecliis maturis subtenuibus, plerumque ovoideis ad ovoideo-lanceolatis. apicibus obtusis, circa 5-8 cm. 

 longis et 2-3 cm. latis. venis secondares angulos circa 40° cum costa iormantibus ; inflorescentia in 

 axillaribus umbellis ad 7 in capitulo, pedunculis ad 5 mm., pedicellis brevissimis; alabastfis parvis, fere 

 ovoideis. calycis tubo fere hemispherieo, operculo hemispherieo ad conoideo ; fructibus parvis, circa 3 mm, 

 diametro fere hemisphericis. valvarum capsularum apicibus conspicue exsertis. 



An Ironbark, "The "\Yandi Ironbark" (H. I. Jensen). A spreading, more or less glaucous tree, 

 giving good shade, attaining a height of 30-40 feet, and with a trunk up to 2 feet in diameter. Rough bark 

 both on trunk and branches. Colour of timber red. 



Juvenile loaves moderately thin, petiolate, slightly oblique, ovate (about 8 cm. long by under 

 5 cm. broad), the secondary veins spreading and making an angle of about 30-10 degrees with the midrib, 

 the intramarginal vein well removed, though not distant, from the edge. (The juvenile leaves seen by me 

 are in the opposite, but perhaps not in the earliest stage). 



Mature leaves thin, mostly ovoid to ovoid-lanceolate, apices blunt ; short. Common dimensions 

 are 5-8 cm. long, with widths of 2-3 cm. Secondary veins making an angle of about 40 degrees with the 

 midrib. 



Inflorescence in axillary umbels up to 7 in the head, with peduncles up to 5 mm. and pedicels 

 very short or absent. The markedly glaucous buds small, nearly ovoid, the calyx-tube nearly hemispherical, 

 and sometime* marked with one or more ribs, the operculum hemispherical to conoid. The anthers very 

 small, opening in parallel slits with gland at the top or near it. Filament at base. Pores round when 

 dried. 



Fruits glaucous, pedunculate, but pedicels very short or absent; small, about 3 mm. in diameter, 

 nearly hemispherical, not tapering at the base ; the capsule markedly distinct from the thin rim ; the tips 

 of capsule-valves distinctly exsert. 



The type is Wancli, Northern Territory (Dr. Harald Ingemann Jensen, No. 372, 

 April, 1916). Photograph available — " Cabbage Gum or Bastard Bloodwood," near 

 Wancli (Dr. H. I. Jensen, No. 378, April, 1916), is very near E. Jenseni, and from the 

 small amount of imperfect material available I cannot detect the difference. I have 

 only quite young fruits, with a sunken capsule, but this may be changed as ripening 

 proceeds. Named in honour of Dr. Harald Ingemann Jensen, the geologist, who, as 

 regards Eucalyptus, has done admirable collecting in the Northern Territory, and 

 in other States, has correlated the species and the soils on which they grow.
