The habit of the two species is different, A. longifolia being a somewhat spindly 
shrub, with comparatively broad phyllodes and intensely yellow flowers. A . floribunda 
has narrower phyllodes, is more bushy, and even attains the size of a small tree. The 
young growth of A. floribunda has a clothing of very fine hairs, not seen except by 
magnification. 
Since Part LVI was written, I am indebted to Prof. A. J. Ewart for the loan of a 
copy of Mueller's " Plants Indigenous to the Colony of Victoria," Vol. ii, of which only 
pages 25 to 32 appear to be extant, and copies of these pages are excessively rare. The 
imperfect work is quoted by Bentham in the Flora Australiensis. 
Following is the description of Acacia longifolia, which is worthy of quotation 
because of the difficulty of obtaining access to it : 
Acacia longifolia Willd. Spec. Plant, iv, 1052 ; Bot. Regist. t. 362 ; Lodd. Cabin, t. 678 ; Bot. Magaz. 
t. 1827 and 2166 ; Maund's Botanist, iv, 197, xii, 269 ; Turpin, Diet. Scient. Nat. t. 259 ; Benth. in 
Hook. Lond. Journ. of Bot. i, 373; Mimosa longifolia, Andr. Rep. t. 207; Vent. Malmais. t. 62; Kern.

Wales, 345. 
Shrubby or arborescent; brancblets very angular; stipules minute, semilanceolate, extremely 
fugacious ; Phyllodia elongate and, narrow oblong-lanceolate, almost straight, with two or three primary some- 
what prominent and several thinner secondary vein-like nerves, imperfectly and distantly reticular-venulose, 
glabrous ; marginal gland conspicuous, above the base or from it somewhat remote ; spikes rather laxly 
many-flowered, solitary, geminate or ternate, sessile ; calyx broader than long, as well as' the minute roundish 
or rhomboid sessile bracteole much shorter than the four-cleft corolla, quadrifid or four-toothed or subtruncate; 
pods thin-cylindrical, almost straight, rostrate, rigid-coriaceous; bivalved, inside continuous, between the 
seeds slightly or hardly contracted ; seeds placed lengthwise, shining, brown-or intense-black, oval, with 
large lateral areoles ; strophiole livid, somewhat cupular, oblique- and short-bilobed, clasping the base of 
the seed, confluent with the short funicle. 
In forest- valley s of the eastern part of Gipps Land ; extending thence through New South Wales. 
A very tall shrub or small tree. Phyllodia thin-coriaceous or subchartaceous, when well developed 
3-8 inches long, 4-12 lines broad, rarely longer or broader, saturated-green-somewhat shining, usually blunt, 
not ^osely streaked, terminated by a minute curved tabescent apiculum. Petioles attaining the length of 
3 lines, usually, however, shorter or quite obliterated. Spikes fragrant, 1-2 inches long, comparatively 
slender ; the single flowers before expansion not closely packed, but leaving little interstices between them. 
Rachis glabrous. Bract at the base of the spike semiovate, concurved, about 1 line long, dropping. Brac- 
teoles often shorter than the calyx, dense- and short-ciliolate. Calyx l-J line long ; teeth usually deltoid, 
as long as or shorter than the tube or evanescent, glabrous or ciliolated. Corolla deeply four-cleft, glabrous, 
about 1 line long. Ovary velvet-downy. Pods 1J-4| inches long, 1J-2 lines broad, squalid-brown; 
valves rather hard, not prominently margined, sometimes very scantily appressed-hairy. Seeds 1J-2 lines 
long ; their areolar lines indicated by paler colour. Strophiole conspicuous, -occasionally truncate, partially 
formed by the closely conduplicated (unicle. 
The bark of this species is used in tanning ; the seeds were formerly used for food by some of the native 
tribes 
The description here furnished is intended for the typical form of A. longifolia. It would appear, 
however, that the following plaftts can merely be regarded as varieties of this species; for although inter- 
mediate forms clearly connecting them are not always known, it must nevertheless be admitted that their 
distinctions rest on so trifling characters as to render it, judging from analogy and considering the effect 
of locality on the different forms, much more advisable to arrange them under A. longifolia as varieties, than 
to vindicate their specific differences.
