Further we have :— 
A. crassiuscula (Wendl. Biss. 31, t. 8), glaberrima, junior subglaucescens, ramulis angulatis, 
phyllodiis linearibus brevissime mucronatis basi longe angustatis crassiusculis submarginatis uninerviis 
venis obscuris, glandulaa basi parum d : stante, racemis phyllodio br. vioribus, capitulis sub-20-floris, calyce 
truncato-dentato crassiusculo ciliato. Phyllodia 1|—2-pollicaria, l|-2 bn. lata, multo crassiora et rigidiora 
quam in A. linijolia, angustiora quam in A. rostelliftra. Raccmi 3-8-cephali. Ovarium g'abrum v. 
toinentosum. Legumen lineare, 2-2£ lin. latum, planum, crassiusculum, glabrum, inter semina contractum, 
valvulis coriaceis.—Blue Mountains, New South Wales, Sieber, n. 464, Cunningham, Fraser, Mitchell. 
(Hooker’s London Journal of Botany, vol. i, (1842), p. 356.) 
Tn the above three extracts, A. crassiuscula is assumed to be an exact 
Australian species, and to be identical with Sieber’s No. 464, and specimens collected 
by others. 
Also we have ( ‘A. crassiuscula, Wendl.,” described in B.F1. ii, 372 (1864) :— 
A. crassiuscula, Wendl. Comm. Acac., 31, t. 8. A shrub of several feet, glabrous and often 
rather glaucous when young; branches usually acutely angled. 
Phyllodia numerous, linear, often falcate, with a small oblique point or the lower ones obtuse and 
almost lanceolate, rather thick, 1-nerved and veinless, the nerve-like margins often but not 
always ciliate, 14 to 2 inches long in some specimens, above 3 inches in others, 1| to 2 or in 
larger ones 3 lines broad, the marginal gland below the middle. 
Racemes shorter than the phyllodia, with several small dense globular heads of 20 or more flowers. 
Calyx turbinate, fully half as long as the corolla, ciliate and readily separating into spathulate 
sepals. 
Petals often separating, with prominent midribs. 
Pod linear, rather thick, about 2J lines broad, contracted between the seeds. 
Seeds in the centre of the pods, but not seen perfect. 
He repeats this in Trans. Linn. Soc., xxx, 473. 
This is in part Sieber’s No. 464, as stated by him, but it includes Queensland 
and Tasmanian plants of whose identity I am in doubt at present, as I have been 
unable to obtain satisfactory specimens. 
I will show, later, that Sieber’s No. 464 is A. obtusata , Sieber, var. Hamiltoni , 
var., nov., which I will figure and describe in Part XLVIII of this work. 
Then Bentham (B.F1. ii, 368, 1864) gives A. crassiuscula, Meissn., in PI. 
Preiss, i, 16 (not of Sieber), as a synonym of A. pycnophylla, Benth. He repeats 
this in Trans. Linn. Soc., xxx, 471 (1875). Meissner’s specimen was collected near 
Albany, W.A. (Princess Royal Harbour). 
So that we have:— 
(1) A. crassiuscula, Wendl. This is A. pycnophylla, Benth. 
(2) A. crassiuscula, Meissner. This is A. pycnophylla, Benth., also (as indeed 
stated by Bentham). 
(3) A. crassiuscula, Sieber. This is No. 464, and is, I repeat, A. obtusata, 
Sieber, var. Hamiltoni, Maiden.
