APPENDIX IV. 337 



Petals separated irregularly from -^ to | way down. Nerves strong and 

 thickened at the tips, with long hairs not quite half way down the flower. 



Pistil exceedingly small and smooth. 



Intermediate forms between the normal form and var. Dunnii were seen at 

 Pine and Horseshoe Creeks (E. J. Dunn). 



After the above was written, I saw " Notes on a new Acacia from Victoria 

 River, Northern Territory," by E. J. Dunn, Proc. Boy. Soc, Vict., xxviii. 

 (new ser.), 228, with two plates. The Acacia is the var. Dunnii just described. 



SERIES JULIFLORAE. 



Sub-Sbbies Rigidulae. 



2i . A. lysiphlosa, F. v. M. — '" 418. 130 miles north of Northern Territory 

 Survey Camp iv., N.T., 10 feet, spreading, rough bark." In flower. 



S2. A. Kelleri, i^. v. 1/.— Described in Proc. Linn. Soc, iV./S.lf ., xvi.,468 

 (1891), from the Durack River, near the better-known Prmce Regent River, 

 M'hich runs into the Cambridge Gulf, North-West AustraUa. 



I have received it from the Lower Victoria River from R. J. Winters and 

 E. J. Dunn, 1913, which is a new record for the Northern Territory. 



23. A. stipuligera, F. v. M. — " 258. 35 miles north-east of Camp 2, 

 7th June, 1911, 10 feet high." In flower. 



■' 358. 40 miles west of Lander Creek, Camp iv., slender bush." 

 In flower. 



Sub-Sebies Stbnophvllae. 



24. A. cyperophylla, F. v. M. — 9. Under this number we have two 

 specimens : — 



(A). " Christmas Creek, Dalhousie Springs Station, S.A., 15th February, 

 1911." Phyllodes only. 



(B). " Bark and seeds," really bark, seeds and pods. 



We are endeavouriag still to ascertain the range and other particulars of 

 ^4. cyperophylla, and I invite attention to part LX. of my " Forest Flora of 

 New South Wales" in this connection, which deals (pp. 275, 276) with its 

 distribution (inter alia) in southern portion of the Northern Territory. 



Dalhousie Springs is a httle south of the Northern Territory boundary, 

 but in the work quoted are some locaUties for this species within the Territory. 



The pods, seeds, and red, curly bark, are those oiA. cyperophylla without a 

 doubt, and the name " Red Mulga" is that generally appHed to this species, 

 but the phyllodes may perhaps belong to another species. I say ,this with 

 some doubt, as we do not yet«laiow for certain the amount of variation in A. 

 cyperophylla phyllodes. 



25. A. pityoides, F. v. M.—" No. 260. 35 miles N.E. of C (arrow) 2, 

 7th June, 1911, 4 feet high." Flower and pod (without seed). 



This specimen agrees with Bentham's description (B. Fl., ii., 400) verj"- 

 well, except in one particular. 



Bentham's words are " Calyx very thin and transparent, deeply lobed, or 

 the sepals quite free but not spathulate, fully two-thirds as long as the corolla." 



Mueller's original description (Jouin. Linn. Soc, iii., 136) simply says : 

 " Sepalis tenerrimis hberis oblongis, corolla triente brevioribus." 



The calyx is truncate, with an irregular edge ; it is thin. It agrees with 

 Mueller's description. (At the same time it is closer to Mueller's Iconography 

 figure of A. xylocarpa than of A. pityoides.)
