Acacia Cuthbertsoni, Luehmann (section, Juliflorse rigidulae). 



A shrub of about 10 feet ; branchlets nearly terete, slightly 

 tomentose ; phyllodia lanceolate or linear-lanceolate, almost 

 straight, narrowed at both ends, with a small oblique point, 

 coriaceous, i 1 /, to 2)4 inches long, 2 to 4 lines broad, ashy-grey 

 from an extremely fine appressed silky pubescence, with about 

 5 to 8 sometimes hardly conspicuous veins. Spikes mostly in 

 pairs, shortly pedunculate, cylindrical, about ^ inch long, not 

 very dense. Flowers mostly 5-merous. Calyx hardly one-quarter 

 as long as the corolla, very thin, with lanceolar slightly ciliate 

 lobes ; petals smooth, free to the base. Pod hard and woody, 

 turgid, gently curved, 3 to 4 inches long, )4 inch broad over the 

 seeds, contracted between them. Seeds longitudinal, broadly 

 ovate, 3 to 3)4 lines long, turgid; funicle short, thin, the second 

 fold dilated into a boat-shaped aril. 



Western Australia, between the rivers Murchison and Gascoyne ; 

 W. Cuthbertson. Near Mount Narryer ; Isaac Tyson. 



The phyllodia are in shape similar to those of A. Kempeana, 

 but with less numerous veins ; the fruit is quite different. 



Acacia palustris, Luehmann (section, Juliflorse stenophyllae). 



Glabrous : branchlets terete, or nearly so. Phyllodia linear- 

 subulate, stout and rigid, terete, pungent, with fine but rather 

 prominent nerves, 3 to 6 inches long. Spikes mostly in pairs, 

 shortly pedunculate, dense, ovoid or oblong, about 3 lines long. 

 Flowers mostly 4-merous. Sepals spathulate, bract-like, about 

 half as long as the corolla. Petals thin, smooth, soon separating. 

 Pod straight, coriaceous, turgid, 4 to 5 inches long, about 4 lines 

 broad over the seeds, much contracted between them. Seeds 

 about 2j4 lines long, 2 lines broad, very turgid, laterally flattened, 

 encircled by a conspicuous raised line, attached by a small ovate 

 arillus without any filiform funicle. 



Near A. aciphylla. 



Western Australia, in swampy places on the Upper Murchison 

 River ; Isaac Tyson.
