NOTES ON ACACIA. 267 



flatter, the areole more distinct and from oblong to elliptical 

 in shape. The funicle is longer and the seeds are more 

 persistent; remaining hanging from the pod. 



E. Pritzel's No. 559, recorded as A. signaia in Engler's 

 Bot. Jahrb. xxxv, 308, is A. lasiocalyx. 



3. With A. stereophylla Meissn. There is a general 

 similarity of appearance between A. stereophylla and A. 

 signata when in flower, but the phyllodes of the former are 

 much more rigid and thick, with hardly visible nerves, and 

 there is an absence of the reddish nerve-like margins seen 

 in A. signata. As regards the structure of the flower, the 

 calyx and pistil of A. signata are far more hairy than that 

 of A. stereo phijlla, and the shapes and relative sizes of the 

 calyces are different. 



4. With A. Beauvercliana Ewart and Sharman. There 

 is considerable superficial resemblance with the broader 

 phylloded forms of this species. The phyllodes of both 

 species have numerous parallel veins, but those of A. signata 

 have a more prominent central one. The spikes of A. 

 Beauvercliana are nearly sessile and more ovoid, while the 

 structure of the flowers is different, the calyx of A, Beau- 

 vercliana being truncate.

Contrasted by the describer with A. dorat'oxylon A. Cunn. 

 The pod was not seen, and the type came from sand plains 

 near the Gairdner and Hammersley Rivers (at Jerramungup). 



Pods have been received from Kununoppin, January r 

 1917 (Dr. F. Stoward). They differ from those of A. signata 

 in being slightly larger, with thicker, more oblong and 

 larger seeds marked by a spherical areole. The funicle is 

 shorter and the seeds are not pendulous from the pod, as 

 in A. signata.
