122 DE. r. MUELLER ON AUSTRALIAN ACACIJE. 



§ 6. Calamiformes. 



2\. Acacia piNiFOhiA {Benth.in Mitch. Subtrop. Austr.Y>. 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, \-^"' tantum crassa. Flores desunt. 

 Pedunculi leguminigeri fere semunciales. Legumina 2-4" longa, 

 1^-2^" lata. Semina matura deficiunt. 



Num eadem sit ac Acacia pinifolia (Bentham in Mitchell, Trop. Austr. 

 p. 342) comparatio speciminum doeebit. 

 [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 ^. 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 Linncea, xxvi. p. 

 612. 



Ad fluvium Murray. 



Corolla calycem ciliolatum semisuperans. Legumen l|-2" longum et 

 totidem lineas latum chartaceum dilute fuscum inter semina flexuoso- 

 constrictum. Semina ovata nitenti-fusca leviter compressa \\"' longa 

 strophiolo livido fere 1'" metiente suifulta. 



A. 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. 



Frutex laxus ramosissimus pluripedalis. Phyllodia in speciminibus cultis 

 multo longiora et magis compressa quam in spontaneis A. chordo- 

 phyllcB, abs quo etiam differre videtur corolla calycem paulo nee semi- 

 superante. Pedunculi capitulo aequilongi appresso-puberuli. 



24. Acacia sericophylla, n. sp. Subsericeo-puberula, ramis tere- 

 tiusculis, phyllodiis filiformi-linearibus elongatis muticis subtilissime 



striolatis, floribus , leguminibus coriaceis elongatis curvatis 



torulosis inter semina conspicue constrictis extus tenuissime cano- 

 puberulis. 



In eremo ad flumen Suttor. 



Phyllodia 5-8'" longa, 1'" lata, compresso-filiformia canescentia. Le- 

 gumen circiter semipedale circiter 4'" latum. Semina et flores non- 

 dum visa. 



Species A. calamifolice proxima. 



[Of this I have seen no specimen. — G. B,]
