APPENDIX IV. 339 



In the absence of pods and seeds, its closest relation appears to be A. 

 drepanocarpa, F. v. M., from which it differs in the longer phyllodes with 

 solitary glands. 



The flowers are very different, the lobes of the calyx in the new species 

 being narrow, almost spathulate, while the calyx of A. drepanocarpa is cupuli- 

 f orm as figured by Mueller in the Iconography. In the original description of 

 A. drepanocarpa (Journ. Linn. Sac, iii., 137), Mueller says " Floras desunt." 

 Bentham, however, describes the flower (B.Fl., ii., 402) as " with narrow lobes, 

 half as long as corolla," which description, as far as it goes, would be appUcable 

 to the proposed new species rather than to the figure in the Iconography. 



But No. 802 differs in other respects from Mueller's figure or Bentham 's 

 description, and seems to be worthy of specific rank. 



27. Acacia aneura, F. v. 21.—" 22 (duplicate). Henbury Station, 

 Finke River, 10th March, 1911." A form with narrow phyllodes, up to 9 cm. 

 long. The flower is rather old for examination, but the details appear to be as 

 follows : — 



Calyx very narrow and thin, fringed at the apex and deciduous. 

 Petals united about half waj' up, glabrous. 

 Pistil brown with surface finely granulated. 

 Bracts capitate, fringed at the apex. 



28. A. Cuthbertsoni, Imehmann. — " 273. 60 miles north-east of Camp 2, 

 7th June, 1911." 



" 373. 60 miles west of C (arrow) 14, Lander Creek. Pods only. 



29. A. sihirica, S. Le M. Moore.- — "No. 46. Henbury Station, Finke 

 River, 10th March, 1911." In flower. 



" 119. 12 miles south of Ahce Springs, 23rd April, 1911." In flower. 

 119 bis. Charlotte Waters northward. Grows to 15 feet, Macdonnell 

 Range, 23rd March, 1911." In flower. Some of the phyllodes are com- 

 paratively narrow. 



Following is a note on No. 119 : — 



Flower in spikes, 5-merous. Calyx semi-truncate, granulated edge; 

 woolly at the base ; thin, often persistent when the corolla has faUen off.' 

 Petals smooth, united about haff way up. Pistil smooth or hoary. There are 

 broad concave bracts at the base of the spike. 



The original description of A. sihirica in Journ. Linn. Sac, xxxiv., 189 

 (1899) omits the pods, or rather the pods are doubtful, nor do the specimens 

 now quoted supply the deficiency. 



But Diels and Pritzel (Engler's Bot. Jahrb., xxxv., 308), state under 

 A. sihirica, 



" Different from the preceding ( A. aneura), in having broader leaves, but somewhat 

 sunilar to it. Specimen ] J. 5 1 22 collected near Menzies is a tree 5 m. high, the fruit deformed 

 by some gaU-making insect, but left after a time by the insect with little orbicular doors 

 sometimes cordate and emarginate (cf. Spencer Moore I.e., 189). ' 



" The normal fruits entirely similar to those of .4. aneura F. v. M." 



This not only gives the aflSnity of the species with A. aneura, but it de- 

 scribes the pods of A. sihirica. I have not seen No. D. 5122, but I venture to 

 suggest that it is unlikely that the fruits of one species is likely to be " entirely 

 similar" to those of another. 



A. sihirica is most closely related to A. Kempeana, F. v. M. ( Australasian 

 Chemist and Druggist, 1882). It is figured in the Iconography, but the speci- 

 mens quoted in the original description come from widely separated localities 

 no type being mentioned. '
