168 MYRTACEAE 
Distributed from the Kimberley to the Gulf of 
Carpentaria in perennially moist sites in sandy soils. 
Ribbing of the fruit appears to be more accentuated 
in plants from drier regions; plants native to the DR 
have relatively smooth fruit. E. erubescens Carr & 
Carr is a hybrid between this species and E. polycarpa. 
Widely cultivated. 
E. setosa Schauer 
Crooked tree to 5 m, rarely taller; bark brownish, 
bloodwood type throughout. Branchlets, leaves, buds 
and young fruit usually coarsely rusty or yellowish 
hairy or bristly, leaves sometimes glabrous and 
subglaucous. Leaves opposite; petioles 0-4 mm long; 
blades lanceolate, broadly lanceolate, elliptic, cordate, 
37-150 mm long, 20-92 mm wide, L/B c. 1.2. Buds 
obconic to campanulate, 19-40 mm long incl. pedicel, 
c. 10 mm wide; operculum shallow, aristate; stamens 
red, pink or white. Capsules on pedicels 2-15 mm 
long; hypanthium mottled, becoming glabrous, 
urceolate or globose, 22-34 mm long, 20-30 mm 
wide. Seed winged. Flowering and fruiting: all 
months. Fig. 52 
E. setosa as understood at present is a composite 
of taxa ranging in fruit size, leaf size, shape and 
degree of hairiness and extending from northern WA 
to Cape York. The large fruited form described here 
is found from Darwin to Pine Creek on sandy or 
skeletal soils. 
E. tectifica FMuell. 
Tree to 12 m high, deciduous or partly so; bark box 
type throughout. Petioles 10-20(30) mm long. Leaf 
blades concolorous, green or glaucous, narrowly lan- 
ceolate to lanceolate, 54-190 mm long, 13-35(50) mm 
wide, L/B 2.5-8(13). Inflorescence a terminal pani- 
cle. Buds ellipsoid, 6-12 mm long incl. pedicel, 3-4.3 
mm wide; operculum conical, apiculate. Capsules on 
pedicels 0-3.5 mm long; hypanthium thin walled, 
hemispherical to obconic, 4-8 mm long, 4-7 mm wide; 
valves sunken or the tips exserted. Flowering and 
fruiting: Nov - Dec though often irregular. Fig. 53 
Distributed from the Kimberley to the Gulf of 
Carpentaria, Qld. In the DR it occurs in woodland on 
a variety of sites though usually favouring skeletal 
soils. 
E. tetrodonta FMuell. 
Tree to 30 m, usually less; bark grey, persistent, 
fibrous throughout. Leaves alternate, occasionally 
opposite; petioles 11-20 mm long; blades concolorous, 
falcate, lanceolate, 75-250 mm long, 10-53 mm wide, 
Eucalyptus 
L/B 4.2-11.7. Inflorescence of solitary axillary 3- 
flowered umbels or occasionally forming a short 
terminal panicle; peduncles 7-26 mm long. Buds 
clavate or pyriform with 4 prominent sepaline teeth 
at the summit of the hypanthium, persisting in fruit; 
10-22 mm long incl. pedicel, 7-11 mm wide; 
operculum hemispherical, rounded, 4-8-ribbed. 
Capsules on pedicels 0-6 mm long; hypanthium ovoid 
to campanulate, 10-20 mm long, 9-14 mm wide; 
valves + level with orifice. Flowering: June - Oct; 
fruiting: Sept - Oct. Fig. 53 Darwin Stringybark. 
Distributed from the Kimberley to Cape York. With 
E. miniata, a dominant species in open forest on well 
drained soils. One of only two species in the genus 
which reproduces by root suckers. 
E. tintinnans (Blakely & Jacobs) L.A.S.Johnson & 
K.D.Hill 
Tree, often deciduous, 3-12 m high; bark smooth, 
bright orange when newly exposed, becoming 
greyish white. Petioles 22-45 mm long. Leaf blades 
broadly lanceolate, ovate or deltoid to almost 
orbicular, (50)75-125 mm long, 35-75 mm wide, L/B 
1-3. Inflorescence of 7-flowered umbels solitary in 
current seasons leaf axils. Buds sessile or shortly 
pedicellate, globular, 5-7 mm long, incl. pedicels, 
4-5.2 mm wide; operculum hemispherical, rounded 
or rarely minutely apiculate. Peduncles terete, 4-8 mm 
long. Capsules sessile or on pedicels to 4 mm long; 
hypanthium + hemispherical, 3-4 mm long, 5-6 mm 
wide; valves exsert. Flowering: July - Aug; fruiting: 
Aug - Oct. Fig. 53 
Endemic to the NT. In the DR on rocky ridges at 
the Mary R. and on similar sites from Batchelor 
southwards. Formerly known in Darwin as E. alba 
and cultivated under this name. 
E. umbrawarrensis Maiden 
Tree to 8 m, rarely taller; bark smooth and white 
throughout, peeling to pale orange. Petioles 9-18 mm 
long. Leaf blades concolorous, shiny, narrowly

wide, L/B 4-9. Inflorescence of solitary axillary 
7-flowered umbels; peduncles 6-8 mm long. Buds 
fusiform, 8-9 mm long incl. pedicel, 2.5-3.5 mm wide; 
operculum equal to hypanthium in length, narrowly 
conical to rostrate. Capsules on pedicels 1-4 mm long;

3-4.5 mm wide; valves triangular with fine exserted 
fragile tips. Flowering: Jan - Feb; fruiting: Feb - Oct. 
Fig. 53 
NT endemic. Rare in the DR; on sandstone ridges 
in the Pine Creek area.
