[The fewer pinnz and pubescent peduncles in the Australian speci- 
mens induced me formerly to doubt whether they really belonged to 
the 4. Farnesiana, especially as I had not then seen the fruit, and 
the specimens generally were bad. But I have since seen both East 
Indian and South American specimens agreeing precisely with the 
Australian form, and passing gradually into the commoner Tropical 
varieties.—G. B.] 
115. ACACIA PALLIDA (F. Muell., non Willd. que Prosopis species). 
Arborea, glabra, ramulis parum angulatis, spinis crassis curvato- 
divergentibus interdum abolescentibus, pinnis pauci- novem-jugis, 
glandula scutellari inter paria infimum et supremum ovata, foli- 
olis 8-29-jugis oblongis obtusis glaucis venulosis uninerviis, pedun- 
culis axillaribus solitariis monocephalis folio brevioribus angulatis 
medio bracteatis, capitulo globoso glabro, corolla ad quadrantem 
divisa calycem argute dentatum fere triplo excedente, legumine an- 
gusto-oblongo basi attenuato satis compresso recto lzvi enervi, semi- 
nibus verticalibus dilute fuscis quadrato-ovatis. 
In locis minus fertilibus presertim campis apricis Australi: intratropicze 
non rara, No. 76. 
Arbor minor, cortice suberoso sordide cano rugoso et rimoso. Spine 
2-3'" longe basi valde incrassate. Foliola 11-3" longa, 1-1j'" lata. 
Capitula majuscula. Legumina 2-4" longa, circiter }" lata. Semina 
3-4” longa nitoris expertia. 
4. suberose propinqua. 
[The specimens marked 76, from Victoria River, are nearly allied 
to A. Bidwelli, but differ in the longer leaflets, the shorter pods, and
