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

 rigid, mucronate ; inflorescence in pedunculate globular 

 heads containing numerous 5-merous flowers, Avith 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 incurved, with very prominent ribs as in A. gono- 

 phylla, narrowed at the base, and tapering to a short 

 point, 5-125 cm. long by about 1*5 mm. broad, stipules 

 minute, deciduous. Peduncles in pairs in axils, slender, 

 spreading or reflexed, - 7 cm. to 2'2 cm. long, bearing heads 

 of about 6 mm. diameter, containing 40 or 50 florets. 

 Sepals very narrow linear spathulate, ciliate, § as long as 

 petals, which are distinct, tapering below, and smooth. 

 Pod stipitate, linear-oblong, straight, slightly contracted 

 and depressed between seeds, flat, 2*5-5 cm. long by 0*5 cm. 

 broad, valves coriaceous with margins thickened. Seeds 

 longitudinal but sometimes slightly oblique, ovate, flattened, 

 mottled, 025 cm. long; funicle short and slender, dilated 

 at base, but scarcely thickened or folded, about half as 

 long as seed. (Kununoppin, E. Avon district. F. E. 

 Victor.) 



F. v. M. and Tate, in their report on the plants of the 

 Elder Expedition, p. 351, note "Acacia (aff.) gonophylla, 

 Benth., with long phyllodes. W. A. near Barrow Range," 

 and probably this is the same species. As compared with 

 A. gonophylla, Benth.. besides having longer phyllodia, 

 the peduncles are longer, the flower-heads larger and con- 

 taining numerous florets, the ladle-like sepals with a very 

 slender claw and broad orbicular lamina, and about § as 

 long as the petals ; the pod is depressed between the seeds 

 but not contracted on the margins ; the seeds are ovate and 

 flattened, and the funicle is different. 



Acacia uncinella, Benth. — As the fruit of this species 

 is imperfectly known, the following description may be 

 given : — 



Pod (not quite mature) almost sessile, linear, straight, 

 flat, with thickened sutures, slightly contracted between 

 the seeds, obtuse and more or less beaked at the top, maxi- 

 mum length 5*6 cm. by about 02 cm. in breadth. Seeds 

 longitudinal, oblong, funicle thickened and shortly folded
