3. With A. Kempeana F.v.M. This species is figured in Mueller's " Iconography 
of Acacias." The phyllodes of the two species are a good deal similar, particularly 
the bluntly lanceolate Girilambone specimens of A. Burrowi, but the calyx in 
A. Kempeana is much smaller in proportion to the petals, the ovarium is smooth, while 
the broad pod and arrangement of the seeds in A. Kempeana are sharply different from 
those of A. Burrowi. In the absence of pods, the western New South Wales specimens 
have gone under the name of A. Kempeana. 
4. With A. homalophylla A. Cunn. This species is figured at Plate 133, Part 
XXXV, of the present work. (The pod is wrong, but is corrected at Plate 189, Part L.) 
A. homalophylla is the true Yarran (a name under which A. Burrowi sometimes passes); 
it will be seen that A. homalophylla belongs to the Plurinerves, while A. Burrowi belongs 
to the Juliflora3. The two species differ in every important particular. 
Botanical Name. Acacia, already explained (see Part XV, p. 104) ; Burrowi, 
in honour of Gordon Burrow, District Forester, Narrabri, who collected the species 
in the Pilliga district. Mr. Burrow has frequently given me assistance in the elucidation 
of the forest flora of his district. 
Vernacular Name. It is known as " Yarran " in parts of New South Wales, 
being looked upon as a broad-leaved form of the common Yarran (Acacia homalophylla, 
see Part XXXV of the present work). I do not encourage the use of the name for 
A. Burrowi, and therefore propose the name " Burrow's Wattle." 
Flowers. The Queensland form displays the following interesting morphological 
character : The flower falls from the rachis without a calyx ; in other words, the 
corolla conies out " clean." This appears to be caused by a fusion of the truncate 
calyx with the floral bract. This forms a ferruginous honeycomb-like membrane 
(membrana favosus), which surrounds the flowers on the rachis, and separates into 
irregular pieces, becoming deciduous some time after the flower (corolla) has fallen. 
Size. It attains a height of 30 feet and perhaps more. 
Habitat. The type came from the Pilliga, New South Wales (Gordon Burrow). 
The species is known so far from moderately dry parts of New South Wales and 
Queensland. It is known from the Bogan district (Nyngan to Coolabah), and it is 
plentiful in the Pilliga district. In Queensland the typical form is only known from 
Inglewood. 
The slightly anomalous form from Chinchilla, Taroom, and Eidsvold brings it 
more northerly. I have no doubt that search will find many other localities, particularly 
in Queensland. 
New South Wales. Coolabah and Girilambone (R. W. Peacock). " Small trees 
of 12-20 feet, growing in rough stony places at the foothills, near the Railway Station. 
Much resembles Yarran (A. homalophylla) in general appearance." Girilambone 
(J.H.M. and J. L. Boorman). " Currawang." " A scrub, short leaf, Mallee-like growth. 
Nyngan. " (Forest Guard E. F. Rogers).
