122 DR. F. MUELLER ON AUSTRALIAN ACACLE. 
§ 6. Calamiformes. 
21. ACACIA PINIFOLIA (Benth.in Mitch. Subtrop. Austr. p.342.—Acacia 
tenuissima, n. sp.). Glabra, ramulis teretiusculis, phyllodiis tenuis- 
simis elongatis tetragono-filiformibus curvato-mucronulatis, stipulis 
minutis deltoideis diu persistentibus, pedunculis brevibus solitariis 
monocephalis, leguminibus chartaceis lato-linearibus rectis compressis 
marginatis enerviis ad suturas vix flexuosis breviter stipitatis basi et 
apice acutis. 
In locis lapidosis aridis ad originem fluvii M'Arthur sinus Carpentaria 
Gulf. No. 5. 
Frutex 5-8’. Phyllodia 3-8" longa, 1-1" tantum crassa. Flores desunt. 
Pedunculi leguminigeri fere semunciales. Legumina 2-4" longa, 
14-21" lata. Semina matura deficiunt. 
Num eadem sit ac Acacia pinifolia (Bentham in Mitchell, Trop. Austr. 
p. 342) comparatio speciminum docebit. 
[These specimens are in fruit; Mitchell's were in flower; but they 
appear in other respects identical. Dr. Mueller had inadvertently given 
the name of A. tenuissima to two species; but the present one proving 
to be already published, his name will be retained for the one described 
below (No. 74).—G. B.] 
22. Acacia chordophylla, Ferd. Muell. ex Benth. in Linnea, xxvi. р. 
612. 
Ad fluvium Murray. i 
Corolla calycem ciliolatum semisuperans. Legumen 11-2" longum et 
totidem lineas latum chartaceum dilute fuscum inter semina flexuoso- 
constrictum. Semina ovata nitenti-fusca leviter compressa 13" longa 
strophiolo livido fere 1"' metiente suffulta. 
4. ephedroidi inter Juliferas valde cognata. 
23. Acacia leptoneura, Benth. in Hook. Lond. Journ. i. p. 340. n. 64. 
Ad sinum Spencer's Gulf, C. Wilhelmi. 
Frutez laxus ramosissimus pluripedalis. Phyllodia in speciminibus cultis 
multo longiora et magis compressa quam in spontaneis 4. chordo- 
phylle, abs quo etiam differre videtur corolla calycem paulo nec semi- 
superante. Pedunculi capitulo zequilongi appresso-puberuli. 
24. ACACIA SERICOPHYLLA, n. вр. Subsericeo-puberula, ramis tere- 
tiusculis, phyllodiis filiformi-linearibus elongatis muticis subtilissime 
striolatis, floribus. ...... › leguminibus coriaceis elongatis curvatis 
torulosis inter semina conspicue кандан extus tenuissime сапо- 
puberulis. 
In eremo ad flumen Suttor. 
Phyllodia 5-9" longa, 1" lata, compresso-filiformia canescentia. Le- 
gumen circiter semipedale circiter 4" latum. Semina et flores non- 
dum visa. 
Species A. calamifolie proxima. 
[Of this I have seen no specimen.—G. B.)
