Hill and Johnson, Eucalyptus (Myrtaceae) 
509 
Series Punctatae 
Bark smooth, shedding irregularly in scales or large flakes over several years, leaving 
a dull surface becoming granular with age. Juvenile leaves petiolate, opposite for 4-6 
nodes. Adult leaves dorsiventral, variously hypostomatic to amphistomatic. 
Umbellasters 7-or-more-flowered. Disc broad, raised. 
3. Eucalyptus grisea L.A.S. Johnson & K.D. Hill, sp. nov. 
Inter subseriem Punctatosas distinguitur combinatione characterum sequentium: folia 
juvenilia adultaque lata, calyptra moderate rostrata, pedunculus valide applanatus. 
Type: Queensland: Vicinity of Pumphole Spring N of Dooloogarah Creek, NW of Mt 
Moffatt homestead, Martensz 1131 & Johnston, 3 Feb 1977 (holo NSW; iso AD, BRI, 
CANB, MEL). 
Tree to 28 m. Bark smooth, patchy, dark grey brown, grey, orange, cream and whitish. 
Seedling leaves opposite for c. 3-4 nodes. Juvenile leaves disjunct, hypostomatic, 
oblong-ovate, apically rounded, to 100 mm long, 30-50 mm wide, petiolate. Adult 
leaves disjunct, hypostomatic, ovate-lanceolate, acuminate, sometimes falcate, 
100-180 mm long, 30-60 mm wide, petioles 15-40 mm long. Lateral veins not closely 
spaced, anastomosing, at 45-60° to midrib, intramarginal vein distinct, about 1 mm 
from margin. Inflorescence simple, axillary; umbellasters 7- flowered. Peduncles 
strongly flattened, to 4 mm wide, 10-20 mm long. Pedicels angled, 2-5 mm long. 
Mature buds oval, 6-8 mm long, 4-5 mm in diameter. Calyptra as long as hypanthium, 
rounded and shortly rostrate, outer calyptra scar present as a more or less distinct lip. 
Fruit cup-shaped, 8-10 mm long, 7-12 mm in diameter. Calyptra scar a shallow groove 
c. 0.5 mm wide, stemonophore a narrow ridge. Disc slightly raised or flat, ultimately 
incurved and enclosing valve bases, 1.5—3 mm wide. Valves broadly triangular, 
apiculate, exserted and incurved at c. 45°. Seeds glossy, brown, angular, cuboid, c. 1 mm 
long, chaff similar, longer and narrower. 
E. grisea is distinguished in the subseries Punctatosae by the combination of the broad 
juvenile and adult leaves, the beaked calyptra and the strongly flattened peduncle. 
Distribution: Queensland: Consuelo Tableland, Carnarvon Range, west of Bundaberg 
(Fig. 3). 
Ecology: locally common in tall woodland or open forest on basalt-derived clay loam, 
in association with £. melanophloia F. Muell., £. tereticornis, E. laevopinca R. Baker, 
E. melliodora A. Cunn. ex Schauer and Corytnbia erythrophloia (Blakely) K.D. Hill & 
L.A.S. Johnson. This species is notable in that it grows on deep heavy clay soils over 
basalt, in marked contrast to other members of the Punctatosae. In some areas of this 
species range, however, basalts and sandstones are closely associated, and 
characteristically sandstone species such as Corymbia hendersonii K.D. Hill & L.A.S. 
Johnson grow in close proximity. 
Conservation status: not considered to be at risk. 
The epithet is from the late Latin, griseus, 'grey', referring to the bark of the mature tree.
