Since Mr. Beeby's remarks, ^. neglectuin has been found 

 in West Lancashire by Messrs. Salmon, Thompson, and 

 Wheldon. 



New or imperfectly described Species of Acacia 

 from Western Australia. By Alex. Morrison.^ 



Acacia densiflora, n. sp. — Phyllodia subulate, terete, striate; 

 flowers in globular sessile heads, 5-merous, with a short turbinate- 

 lobed calyx. 



A rigid shrub with terete, closely woolly-pubescent branches, 

 phyllodia subulate, somewhat spreading, terete but slightly flattened, 

 rigid, mucronate but scarcely pungent, slightly narrowed at base, 

 with 15-20 rather prominent striae and minutely pubescent, o-8- 

 2 '5 cm. long and about i mm. thick. 



Inflorescence in globular sessile flower-heads crowded in pairs in 

 the upper axils ; flowers about 20 or fewer in the head, 5-merous, 

 calyx turbinate with short lobes, woolly, less than half as long as the 

 petals, which are subacute, smooth, with the midrib somewhat 

 prominent near the top. Pod not seen. (Kellerberrin, E. Avon 

 district. R. B. Leake.) 



Meissner describes a barren specimen from the interior (Preiss, 

 No. 976, "PI. Preiss," i. 12) as a possible variety of ^. leptoneura, but 

 Bentham in " Fl. Austral" has placed this under A. aciphylla 

 without, however, having seen Preiss's specimen. Our plant, 

 if it should be the same as that collected by Preiss, differs in 

 aspect from A. aciphylla, being a scrubby, rigid shrub, with the 

 flower-heads distinctly globular, so that Meissner seems to have been 

 nearly right in placing it under A. leptoneura. Moreover, although 

 the calyx is that of A. aciphylla, the globular flower-heads and the 

 phyllodia approach those of A. leptoneura, so that this plant may be 

 set down as a distinct species. 



Acacia longispinea, n. sp. — Phyllodia linear tetragonous, rigid, 

 mucronate ; inflorescence in pedunculate globular heads containing 

 numerous 5-merous flowers, with free sepals and petals ; pod flat, 

 straight, seeds ovate attached by a short funicle without folds or aril. 



A glabrous shrub with terete branches, the phyllodia being in- 

 curved, with very prominent ribs as in A. gonophylla, narrowed at 

 the base, and tapering to a short point, 5-12*5 cm. long by about
