NOTES ON ACACIA. 245 



A. spodlosperma from the Gascoyne River, Mrs. Gribble, 

 1886, given me by Prof. Ewart, and also a specimen labelled 

 A. sclerosperma P.v.M. (by Mueller) in pod only, Nickol 

 River, W.A. (A. Forrest), given by Mr. Luehmann to me 

 in 1897. I consider them, from the material available, to 

 be identical with (2) and (3). 



In the original description of A. sclerosperma, Mueller 

 says "Foliage resembling that of A. dentigera (misprint 

 for dentifera) and A. pycnophylla. 



(2) A. spodiosperma F.v.M. type, Proc. Linn. Soc. N.S.W. 

 iii, (2nd Ser.) 164 (1888). Near Lake Austin, W.A. H. S. 

 King. Considered by Mueller at the time to be aff. A. 

 scirpifolia and A. calamifolia, but now, I think correctly, 

 placed near A. salicina Lindl. 



(3) A. leucosperma F.v.M. MSS. Quoted by Pritzel in 

 Engler's Bot. Jahrb., xxxv, 302, (1905), and described by 

 him as F.v.M. ined. and Pritzel. See also a note on it by 

 Ewart and White, Proc. Roy. Soc. Vict., xxii, 91 (1909). 



I offer a translation of Diels and Pritzel's remarks, as 

 the species has been otherwise only imperfectly described. 



A. leucosperma F.v.M. ined. et E. Pritzel n. sp. 



In the Melbourne Herbarium I found a specimen collected by 

 H. S. King near Lake Austin, named by F.v. Muller A. leucosperma 

 n. sp. but never publicly described. From more complete specimens 

 collected by us this species may be described : — 



A shrub or tree up to 3-5 m. high, very glabrous, the young 

 parts often glaucescent. Phyllodes spreading, linear, obtuse at 

 the apex, subtruncate or curved back, somewhat thick, without 

 nerves except for the prominent middle nerve, pale or glaucous 

 green. Heads solitary in the axils or shortly (up to 3), racemose, 

 peduncles conspicuous, heads conspicuous about 20 flowered. 

 Flowers 5-merous, calyx shortly truncate, petals smooth. The 

 pod when quite ripe having woody valves strongly arched above
