1. Eucalyptus incrassata Labill., Nov. Holl. PI. Sp. 2: 12 (1806), tab. 150; non Sieber ex 
DC., Prodr. 3: 217 (1828), nom. illegit. 
Type: south-western Australia, J.J.H. Labillardiere s.n. (holo FI; iso BM, G, LINN, MEL). 
Cited as 'Habitat in terra Van-Leeuwin', and specimen annotated 'Nova Hollandia'. 
The type of E. incrassata matches specimens of the taxon we are designating as 
E. incrassata sens, strict., which is intermediate in morphology between E. angulosa and 
E. captiosa (Fig. 1, and see Table 4). It occurs sporadically from the Stirling Ranges to 
east of Esperance along the south coast of Western Australia (Fig. 2), but appears to 
form distinct populations in a complex geographic mosaic with E. angulosa near the 
coast and E. captiosa further inland. 
Mallee to 6 m tall. Bark smooth, grey to grey-brown, shedding in ribbons. Juvenile 
leaves disjunct, elliptical to ovate, to 8 cm long, 5 cm wide. Adult leaves disjunct; 
broad-lanceolate to elliptical, acuminate, glossy bright green, 5.0-11.0 cm long, 9-30 nun 
wide; petioles terete, 15-20 mm long; lateral veins at 35-45° to midrib, moderately 
spaced, ± degenerate; oil glands dense and distinct; intramarginal vein 1-3 mm from 
margin. Umbellasters axillary, 3-7-flowered; peduncles flattened, apically expanded, 
10-28 mm long; pedicels terete to slightly quadrangular, 15-23 mm long. Mature buds 
ovoid, weakly to moderately costate, 12-16 mm long, 4-7 mm diam.; calyptra conical, 
often beaked, c. Vz as long to as long as hypanthium. Fruits cup-shaped to cylindrical, 
weakly costate, 3-4-locular, 9-16 mm long, 7-12 mm diam.; calyptra scar and 
stemonophore flat, c. 0.5-1 mm wide; disc steeply depressed, 1.5-3 mm wide; valve 
tips raised to rim level. Seeds ± pyramidal, deeply and regularly pitted, not winged, 
black, 1.0-2.0 mm long; hilum ventral; chaff red brown, smaller, angular (Fig. la, b)

Intergrades: E. angulosa <h> E. incrassata 
Selected specimens (from 2 examined): Western Australia: 14.2 km S of highway on track to Eyre 
telegraph station (now Eyre bird observatory), Hill 2171 & Johnson, 3 Nov 1986 (NSW, CANB, MEL, 
PERTH). 
2. Eucalyptus angulosa Schauer, in Walp., Repert. Bot. Syst. 2: 925 (1843). 
Type: Western Australia: Swan River Colony, J. Drummond 4: 75 (lectotype BM, here 
designated; isolecto CGE, FI, K, PERTH, W). No type was cited in the protologue, and 
Schauer may have used collections by Brown, A. Cunningham, Labillardiere or 
Drummond in drawing up the description. This typification clearly fixes the name to 
the coastal taxon generally understood to be represented by this name.

E. angulosa was reduced to a variety of E. incrassata by Bentham (1867), which 
treatment was followed by Maiden (Crit. Revis. Eucalyptus 1903-1933, 1: 101). Blakely 
reverted to Schauer's treatment, then Burbidge (1947) followed Bentham with a 
narrower circumscription. Pryor and Johnson (1971) included E. angulosa in
