CONTRIBUTIONS TO THE QUEENSLAND FLORA, NO. 9.

Acacia aulacocarpa A. Cunn. as understood by Australian botanists 
is one of the most widely distributed of wattles. Unfortunately, I have 
not seen any types and have placed A. crassicarpa A. Cunn. as a synonym 
of Bentham ’s variety macrocarpa following his description and a drawing 
of the pod of the type of A. crUssicarpa A. Cunn. by Maiden (Proc. Roy. 
Soc. Queensl. xxx, pi. VII : 1918). In the field this variety can generally 
be distinguished by its larger broader phyllodes up to 5 cm. wide, but 
this is not an invariable character, the only true distinction being the 
very broad and woody pod. It has not been found outside the tropics. 
Acacia aulacocarpa A. Cunn. var. fruticosa var. nov. 
Frutex 0.75-3 m. altus, ramulis validis acute triangularibus ; 
phyllodia ad 9 cm. longa, 1.5-2. 5 cm. lata, 3-5-plo longiora quarn lata; 
spicae 2.5-4 cm. longae, floribus aurantiacis ; legumen ca. 5 cm. longmm 
et 1 cm. latum, valvis crassis subligneis lineis obliquis valde elevatis 
notatis. 
Moreton District : Ngun Ngun, Glasshouse Mts., alt, 800 ft., common 
on top and rocky slopes of the mountain, C. T. White 7651 (type: 
fls. and old pods), 20-3-1931 (shrub or small tree up to 3 m. high, fls. 
deep orange) ; Mt. Coolum, on the summit, Mrs. M. S. Clemens (very 
young fl. spikes and old pods), April 1945 (shrub 2 ft.) ; Wide Bay 
District: Mt. Cooroora, alt, abt. 800 ft., C. T. White 1889 (fls.), March 
1923 (small bushes 3-4 ft. high with very bright flowers). 
This variety is distinguished by its shrubby habit, strong acutely 
triangular branchlets, deep yellow flowers, as opposed to the very pale 
yellow of typical A. aulacocarpa A. Cunn., narrow pods with somewhat 
more woody valves and the oblique lines or costae on them thicker and 
in consequence more prominent. 
As I understand the three varieties they can be distinguished as 
follows : — 
Trees, phyllodes including the petiole 7-18 cm. long, 1-5 cm. wide, 
4£-9 times as long as broad, spikes with the peduncle 2.5-7 cm. 
long, flowers pale yellow. 
Pods usually about 1.5 cm. wide but varying from 1-2 cm., 
valves rather thin, scarcely woody . . . . . . A. aulacocarpa. 
Pods usually about 2.5 cm. wide but varying from 1.5-3 cm., 
valves thick and woody . . . ." . . . . . . A. aulacocarpa 
var. macrocarpa. 
Shrub or at most a small tree 3 m. high, phyllodes including the 
petiole 5-9 cm. long, 1.5-2.5 cm. wide, 3-5 times longer than 
broad, spikes with the peduncle 2.5-4 cm. long, flowers bright 
yellow. Pods about 1 cm. broad, valves woody or almost so A. aulacocarpa 
var. fruticosa. 
Bossiaea microphylla 8m. in Trans. Linn. Soc. ix, 303 (1808). 
Darling Downs District: Nr. Ballandean, Mrs. M. S. Clemens (fls.), 
Oct. 1944. 
A very common shrub in N.S. Wales and Victoria, not previously 
recorded for Queensland. 
Maniltoa sp. 
Cook District: Chilli Creek, 5 miles S.W. of Portland Roads, 
^ apt. W. L. Scott (leaves and leaf-buds), 10-4-1944. 
The above specimens are sterile and therefore cannot be accurately 
identified specifically, but they are recorded here as the genus is new 
to Australia,
