long as the sepals, free and slightly pointed at the free ends. — 
Stamens numerous. — Fruit much twisted and constricted between the 
seeds, 2,5—3 inches in length, pointed at both ends. — The species 
would come in the Series III, Pungentes of Bentham, on account of its 
possessing phyllodia, spinescent branches and cylindrical inflorescence. 
This last character would place it into the Sub Series D. Spicatae, from 
which, however, it differs in having 5-merous flowers. In this respect 
apparently, the definition of the subseries might be extended. Baron 
von Mueller placed the sub-section Spicatae under the Jwliflorae, which 
seems on the whole a less artifical arrangement than Bentham's. This 
species is the only one of.the Spicatae sub-section found in West 
Australia, whereas the remainder of the Juliflorae includes Western as 
well as Eastern species. — West Australia: Watheroo Rabbit fence,

49. Acacia leptoneura Benth. var. eremophila Ewart and White, l. c., 
p. 286, pl. L, fig. 1—4. (A. eremophila W. V. Fitzgerald, MS.) — The 
principal characters in this new variety are: — Shrubs 1'/,—2 feet 
high, the young stems closely covered with woolly grey hairs. Phyllodia 
almost terete, but slightly flattened, glabrous, about 2 inches long, with 
small recurved points. — The inflorescence is almost sessile, and com- 
posed of 10—15, 5-merous flowers. Sepals rectangular, united about 
half their length. Petals free, obtuse, smooth. Ovary sessile, nearly 
glabrous. Pods (only seen when young) !/,—1 inch in length, and less 
than 1 line in breadth, very much twisted and covered with dense

woolly grey hairs; not constricted between the seeds. — This specimen 
was made into a new species by W. V. Fitzgerald, but no technieal 
description has been published hitherto. — The chief difference between 
it and Bentham's description of leptoneura is that there are fewer flowers 
in the head than in the typical A. deptoneura, and hence the heads are 
smaller. The no. 1338a, of Max Koch appears to be typical A. lepto- 
neura, but has no fruits. — West Australia, Cowcowing, Max Koch,

50. Acacia Ewartiana (W. F. Fitzgerald, MSL White, l. c., 287, pl. L, 
fig. 5—7. A shrub 2—3 feet high. — Stems nearly terete, glabrous. — 
Phyllodia nearly terete, somewhat curved with several longitudinal veins, 
rigid, usually !/—?/, inch in length, rather obtuse at the tip, where 
there is a small straight or very slightly hooked pungent point, dis- 
tinetly articulated on the stem. Scattered stipules either absent or deci- 
duous. The heads are very small and globular, measuring about 1 line 
in diameter, and composed of about 10 small 5-merous flowers, axillary, 
solitary, on slender pedicles of 1—1!/, lines in length. Bracts broad, 
pointed at the ends, brown. — Sepals only united at the extreme base, 
not exceeding half the length of the petals, obtuse, edged with short 
processes, Petals united about !/ their length, the 5 lobes being rather 
smooth, obtuse. — Stamens numerous. Ovary sessile, glabrous. Fruit 
not seen. Acacia Ewartiana seems to fall under Series III. Pungentes
