The venation is certainly more like that of the latter species, as 
is also the vestiture, but the long peduncles, phyllodes and straight 
pod remove it far from that species. If there were any varietal 
forms it might perhaps be made a variety of A. lanigera, but as 
specimens of that species obtained from the interior of the Colony 
and from many parts of the Dividing Range show no perceptible 
variation, it is impossible to look upon our plant as a variety. 
We may also mention that the sucker or switch-like appearance 
of the stems of A. Baeuerleni in no way resembles the close thickset 
shrub A. lanigera. The bracteoles appear also to be wanting or 
are very deciduous. 
The individual flowers and head are also larger than those of 
A. lanigera, while the stamens have white filaments and light 
yellow anthers. 
The pods also show no tendency to curve. 
Had it come under the Plurinerves, then its affinities would be 
with A. elongata and A. Simsii, from which species it differs 
mostly in the shape of the phyllode, length of peduncle, calyx, 
and shape of seed and aril. 
Dedication. — This species is named after Mr. William Baeuerlen, 
the painstaking botanical collector of the Technological Museum. 
Albizzia (Pithecolobium) Muelleriana, sp.nov. 
(PL LII.) 
A tree glabrous in all its parts, height about 50 to 70 feet, as- 
seen, diameter 2 feet, locally known as "Ash." 
Pinnae one pair, rarely two pairs, the common petiole mostly 
under one inch, each rhachis often short, rarely exceeding two 
inches. Gland wanting. Leaflets glabrous, usually one pair sub- 
tended by an odd one, exceptionally composed of three or four 
leaflets irregularly placed along the rhachis, ovate acuminate, obtuse, 
or oblanceolate, acuminate, the cuneate base narrowing into a 
distinct hairy or pubescent petiolule, articulate with the rhachis; 
1 to 5 inches long, reticulately penniveined on both sides, but 
much more prominently so on the underside, paler above.
