Telopea 8(4): 2000 
7-9 mm long, 3-5 mm diam.; calyx calyptrate; shedding early; corolla calyptrate, free 
from calyx; calyptra hemispherical to broadly conical, smooth, about as long as or 
slightly shorter than hypanthium, as wide as hypanthium; hypanthium smooth. 
Flowers white or cream, all stamens fertile, filaments irregularly flexed in bud, anthers 
versatile, oblong, dehiscing by parallel slits; style base not sunken. Fruits cylindrical, 
pedicellate, 3-locular, smooth, 5-8 mm long, 4-6 mm diam.; calyptra scar flat, 0.5 mm 
wide; stemonophore depressed, 0.2 mm wide; disc depressed, not incurved, 1-2 mm 
wide; valves enclosed, raised at 60-80° to vertically raised. Seeds flattened-ovoid, 
shallowly finely reticulate, semi-glossy, yellow-brown, c. 1 mm long; hilum ventral. 
Chaff dimorphic, linear and cuboid, similar in colour to seeds. (Fig. 9). 
Two allopatric subspecies may be recognised on differences in fruit morphology.

6B. Eucalyptus leucophloia Brooker subsp. euroa L.A.S. Johnson & K.D. Hill, subsp. nov. 
Ab subspecie leucophloia distinguitur: valvae manifeste exsertae. 
Type: Northern Territory: 34 km S of Macarthur R crossing on Tablelands Highway, K.D. 
Hill 1023, L.A.S. Johnson & D. Benson, 6 Aug 1984 (holo NSW; iso CANB, DNA, PERTH). 
[E. leucophloia subsp. QQ Brooker & Kleinig 1994)] 
Readily distinguished by the steeply raised and prominently exserted valves. 
Distribution: across the drier monsoon tropics of the Northern Territory and 
Queensland, from Top Springs east to Cloncurry, and from Daly Waters south to 
Wauchope (Fig. 10). 
Ecology: widespread in open savanna woodlands on shallow sandy soils on sandstone. 
Some intergrades with E. brevifolia occur to the west of Top Springs in the Northern 
Territory. 
Conservation status: not considered to be at risk. 
The epithet is from the Latin eurous, eastern, referring to its occurrence in the eastern 
part of the species range.
