NOTES ON ACACIA. 181 



Pod pale brown, covered with a fine tomentum, broadish, 

 curved, up to 11 cm. long and more, about 5 mm. broad, 

 chartaceous, reticulate, convex over the seeds. 



Seeds brown, ovoid, longitudinally arranged; funicle long, 

 filiform-flattish, crimped, encircling the seed round the 

 longer half, and terminating in a short aril. 



This description has been drawn up, as regards habit, 

 phyllodia and fruit, from the Port Augusta specimens 

 (J.H.M.) which I constitute the type. The details of the 

 flower have been described from the Eucla specimen. 



This very interesting South Australian species has been 

 named in honour of Sir William James Sowden, of Adelaide, 

 President of the Australian Wattle Day League. 



Range. 



Its range appears to be confined to South and Western 

 Australia. We know it from the head of Spencer Gulf in 

 South Australia, then roughly following the Transconti- 

 nental Railway Line it extends just in to Western Australian 

 territory at Eucla. It is one of those species which on its 

 foliage alone has been passed by as something else, and 

 there has been so much confusion in regard to our Acacias 

 that only the trained collector can pick out suitable 

 material to collect and make appropriate notes. And our 

 country is so vast, and the botanical workers so few, that 

 it is but rarely the trained collector passes over our sparsely 

 peopled areas. 



South Australia. 



Ten to fifteen feet or even twenty feet. Shapely, con- 

 sisting of many stems, almost like a Mallee. Very hand- 

 some, with its silvery somewhat weak foliage. Port 

 Augusta (J.H.M., Jan, 1907). 



"Myall." North of Kingoonya, East West Railway to 

 Commonwealth Hill, north east of Ooldea (Dr.H. Basedow, 

 No. 95, April, May, 1917). Some valves and phyllodia.
