Hill and Johnson, Eucalyptus (Myrtaceae) 
531 
12-26 mm long; lateral veins closely-spaced, regular, at 40-60° to midrib; reticulum 
even, dense; oil glands small, obscure; intramarginal vein continuous, distinct, <1 mm 
from or at margin. Inflorescences compounded, pseudoterminal or lateral; unit 
umbellasters 3-7-flowered. Peduncles terete, (3—)6—23 mm long. Pedicels terete or 
angular, thick, 2-9 mm long. Fruit conical to cup-shaped or cylindrical, 4-5-locular, 
7—11 mm long, 6-8 mm diam.; calyptra scar and stemonophore raised or flat, 0.5-0.7 mm 
wide, often with a persistent staminal ring; disc flat to steeply depressed, 1-2 mm 
wide; valves broadly triangular, obtuse, basally enclosed, apically rim-level or 
exserted, raised at 45—90°. Seeds semiglossy to dull, brownish-black or black, rounded, 
elliptical, regularly shallowly reticulate; hilum ventral. Chaff mid-brown. (Fig. 15). 
E. limitaris is distinguished by the relatively thin, dull green leaves with no glaucous 
bloom, the long pedicels and peduncles, and the large conical or cylindrical fruit. 
Distribution: southern Kimberley region, from west of Fitzroy Crossing to Halls 
Creek, and east to west of Top Springs (Fig. 16). 
Ecology: locally common but sporadic, on shallow red loam over various rock types, 
in open savanna shrubland, often near dry creek lines. 
Pure populations occur in the west of the range around Fitzroy crossing, and again in 
the east towards Top Springs. Extensive breakdown occurs however with E. tepluodes 
around Halls Creek. E. limitaris and E. tephrodes display a similar extensive breakdown 
pattern to that seen with the E. tropica Cambage-E. leucophylla Domin, E. xerothermica- 
E. tephrodes and E. epruinata-E. microneura pairs. E. limitaris and E. tephrodes however 
show extensive pure stands of the parent species, and a degree of ecological separation
