Halford & A.J.Ford (Forster & Halford 2007). 
A third Australian species of Coelospermum , 
from north-eastern Queensland, is here 
described. 
Materials and methods 
The study is based upon the examination 
of herbarium material from BRI and CNS 
(formerly QRS) with field observations by the 
second author. All specimens cited have been 
seen by one or both authors. Measurements of 
the floral parts and fruits of Coelospermum 
purpureum are based on material preserved 
in 70% ethanol. Common abbreviations in the 
specimen citations are: L.A. (Logging Area), 
N.R/R. (National Park/Reserve), S.F.R. (State 
Forest Reserve) and T.R. (Timber Reserve). 
The abbreviation RE in the distribution and 
habitat notes refers to Regional Ecosystem, 
descriptions of which can be viewed at (in 
this case); www.epa.qld.gov.au/projects/redd/ 
landzone.cgi?bioregion=7. 
Extent of occurrence estimates were 
derived from the validation of original 
collection localities. These data points were 
loaded into ESRI ArcView 3.2 and the 
draw polygon feature was used to calculate 
the area between the points. The area of 
occupation estimates were principally 
derived from a digital Regional Ecosystem 
map supplemented by the second author’s 
knowledge of vegetation types and habitats 
within the Wet Tropics bioregion (referred to 
as the Wet Tropics hereafter) (Environment 
Australia 2005).

planis (vice foliorum crassorum viridium vel 
flavoviridium marginibus reflexis) et tubis 
corollarum longioribus (8-13 mm longis vice 
3-7 mm) differt. Coelospermum purpureum

Bushy shrub to 5 m high (usually umbrella¬ 
like) or small tree to 10 m high, stem diameters 
to 8 cm dbh, glabrous. Bark brown, lacking 
distinctive features. Wood yellowish, roots 
brownish. Branchlets laterally compressed 
(elliptic in transverse section), becoming ± 
terete with age; bark on old twigs somewhat 
flaky, leafy twigs varnished to smooth, 
purple when fresh; flattened slightly at nodes; 
raphides present. Leaves petiolate, opposite; 
stipules interpetiolar, sheathing, 1.5-2 mm 
long, produced into a narrow triangular lobe, 
purple when fresh, glabrous, fragmenting as 
node thickens; petioles 7-15 mm long, purple 
when fresh; blades discolorous, leathery and 
thin, narrow-elliptic, sometimes narrow- 
obovate, 7-15 cm long, 1.9-5 cm wide; 
adaxial surface shiny or glossy, dark green; 
abaxial surface much paler than adaxial 
surface; venation brochidodromus with 5-7 
lateral veins per side of midvein; lateral veins 
slightly raised on both surfaces, slightly 
more prominent on abaxial surface; tertiary 
venation not raised; apex acuminate; base 
cuneate; margins entire; domatia absent. 
Inflorescence terminal, 2-4-flowered umbel¬ 
like, pedunculate dichasium (rarely with 
an additional 3-flowered umbel-like cyme); 
peduncle 10-36 mm long, glabrous, terete; 
bracts c. 0.5 mm long, glabrous. Flowers 
faintly perfumed, (3)4(5)-merous, bisexual;
