placed the sub-section Spicatae under the Juliflorae, which seems 

 on the whole a less artificial 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. The above manuscript name 

 was attached to the specimen by W. V. Fitzgerald, but no de- 

 scription of the plant has hitherto l^een published.

Cowcowing, West Australia. Max Koch, 1904, No. 1024a. 



The principal characters in this new varietj- are: — Shrubs 

 \\-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 composed of 10-15, 

 5-merous flowers. Sepals rectangular, united about half their 

 length. Petals free, obtuse, smooth. Ovary sessile, nearly gla- 

 brous. Pods (only seen when young) \-\ 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. Fitz- 

 gerald, but no technical 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. leptonetwa, and hence the heads are smaller. 

 The No. 1338a, of Max Koch appears to be typical A. lejJtoueura, 

 but has no fruits. 



Of two fruiting specimens placed under A. leptoneura by 

 Baron von Mueller, one (Mt. Jackson, Young, 1875), has pods 

 6 centimetres long, by about 2 millimetres broad, not or veiy 

 slightly constricted between the seeds, the other (Mrs. Heal, 

 Swan River, 1890), has pods 3 or 4 centimetres long, little more 

 than a millimeti-e broad, and strongly constricted between the 

 seeds. This was at first considered the type of a new species, but 

 subsequently placed by Mueller under A. leptoneura. If so, it 

 represents a well-marked variety, but both these fruiting speci-
