Distribution and habitat : Eucalyptus 
woollsiana is widespread from southern 
Queensland (e.g. Injune, Chinchilla) to 
southern inland New South Wales (Map 
1). The actual southern extent is blurred by 
intergradation with Eucalyptus microcarpa. 
In Queensland and northern New South Wales, 
it frequently grows on flat land with brigalow 
{Acacia harpophylla ) or belah {Casuarina 
cristata ), on heavy black clay soils. Further 
south, it tends to grow on undulating terrain 
with other eucalypts, notably Eucalyptus 
Austrobaileya 8(1): 25-34 (2009) 
populnea. The soils, while still clayey, vary in 
colour and texture. 
Typification: There has been considerable 
confusion about the typification and 
application of this name since its publication 
on 20 th May 1901. 
Maiden (1921: 202) wrote “I have 
received, in response to my request for types 
[of E. woollsiana ], specimens labelled by 
Mr. Baker, Condobolin and Girilambone to 
Condobolin” The two sheets mentioned by 
Maiden, namely “Condobolin” (NSW118270) 
and “Girilambone to Condobolin” 
(NSW118269) both belong to a taxon in the 
Eastern grey box group, allied to E. moluccana 
and E. microcarpa. Gillison (1976) and 
Chippendale (1988) accepted Baeuerlen’s 
“Girilambone to Condobolin” specimen as 
the type of E. woollsiana. 
However, Article 9.10 of the International 
Code for Botanical Nomenclature states that 
the lectotype must be chosen from amongst 
the syntypes, if such exist. Baker’s protologue 
corresponds to a minimum of five specimens, 
some collected by W. Baeuerlen and some 
by R. Cambage. It is apparent that only three 
gatherings matching the protologue details are 
now extant at NSW, where Baker’s herbarium 
is now housed. They are 1. Girilambone, 
March 1900, Baeuerlen 2578] 2. Girilambone, 
January 1900, Baeuerlen s.n.] and 3. Nyngan, 
June 1900, R.H. Cambage s.n. 
Both of the Baeuerlen gatherings are 
referrable to Eucalyptus viridis R.T. Baker. 
Only the Cambage gathering is referrable to 
the species of tree-form with the short pedicels 
and lanceolate juvenile leaves. Article 9.17 
of the Code states that when the synytpes 
comprise more than one taxon, the chosen 
lectotype must be in accordance with the 
taxon that best matches the description given 
in the protologue. In this case, the species of 
tree-form with short pedicels and lanceolate 
juvenile leaves is clearly the intended species. 
Therefore, the Cambage specimen at NSW is 
designated as the lectotype. 
Notes: It is not surprising that Baker and 
later workers confused herbarium material 
of Eucalyptus woollsiana and E. viridis.
