164 description of two unrecorded west australian plants. 



Acacia spodiosperma. 



Glabrous ; branchlets whitish, cylindrical ; stipules obliterated ; 

 phyllodes rather long, compressed-cylindrical, without any per- 

 ceptible longitudinal venules, recurved-pointed, through exsicca- 

 tion wrinkled ; headlets few -flowered, solitary or two or three 

 above each other, on rather long stalks; calyx lobeless, considerably 

 shorter than the smooth corolla ; fruits few-seeded, compai'atively 

 broad, much compressed, generally arcuate-curved, only slightly 

 attenuated at the base, deeply constricted between the seeds, 

 hardly or tardily dehiscent ; pericarp rather thick ; seeds roundish, 

 considerably compressed, brownish- white when nearly ripe ; areoles 

 almost as wide as the whole seed ; arillar appendage very small, 

 nearly semi-orbicular ; funicle brown, capillary quite short. 



In the vicinity of Lake Austin (H. S. King, Esq). 



This species diffei's already from A. scirpifolia in shorter phyl- 

 lodes with more curved apex, in fruits much wider dilated between 

 the constrictions and in the minuteness of the arillus ; from A. 

 calamifolia it is distinguished by the form of the calyx, by the 

 broadness of the fruit, and by the roundish form and larger size 

 of the seeds ; from both, moreover, and indeed from all other 

 Australian congeners it is removed by the paleness of the seeds ; 

 the latter, however, in a ripe state were not available, nor well- 

 developed headlets of flowers yet for examination.
