2. Acacia Muelleri, Benth. in Linnea, xxvi. p- 603. (Acacia mega- 
phylla, Ferd. Mueller, MS.) 
In ditione districtus Portus Lincoln, C. Wilhelmi. 
Phyllodia crasso-coriacea raro oblongo-lanceolata. Capitula lete lutea. 
Calyz 1" circiter longus glaber campanulato-cylindraceus ; dentes 
breves triangulares cosmiventes. Petala lanceolato-linearia inferne 
coherentia. Legumina coriacea fusca compressa oblonga ad crassum 
marginem flexuosa oligosperma circ. 1j" longa, fere }" lata, iu 
stipitem brevem contracta, intus continua. Semina compresso-ovata 
e sordide cano et nigro variegata. Strophiolum lividum cymbiformi-

[In publishing this species as A. Muelleri, I stated my reasons for not 
adopting Dr. Müller's manuscript name, which appeared to me too little 
appropriate in a genus which contains so many species with phyllodia 
twice or three times as large.—G. В.]

4. ACACIA PRAVIFOLIA, п. sp. Puberula, ramulis rigidis spinescen- 
tibus teretibus striatis, stipulis brevibus setaceis v. subulatis deciduis, 
phyllodiis parvis triangularibus crasso-coriaceis paucinerviis acutis 
mucronatis, angulo superiore valde protracto obtuso eglanduloso, 
capitulis subsessilibus v. breviter pedunculatis axillaribus solitariis, 
bracteolis magnis subcordatis, sepalis spathulatis diu cohwerentibus 
corollam dimidiam squantibus margine ciliolatis, leguminibus pubes- 
centibus spiraliter contortis. 
In montibus Flinders et Elder's Range, et ad Crystal Brook. 7 
Phyllodia 11-3" longa et lata, iis A. decipientis non absimilia, nervo 
infimo magis prominente. Flores l"'longi. Calyz satis laxus. Le- 
gumina circ. 11'" lata. | 
Tilustris Bentham forsan optime judicans hancce speciem cum sua 4. 
sublanata combinat, tacens autem de bracteolarum indole et ramo- 
rum rigiditate pungente. Nee vidit pedunculorum brevitatem. Le-
