distance it would be impossible to distinguish them. In view 

 of the unisexual character of many, if not of all the flowers, 

 it is evident that Moore's generic description must be partially 

 altered.

Angianthus Whitei, J. M. Black. Broken Hill, N.S.W.. 

 (A. B. Black). As this plant has now been found so close to 

 our eastern border, and as the type comes from Corunna 

 Station, E.P., it probably inhabits some of the intervening 

 country (Tate's District S).

 All the efforts I have made to distinguish satisfactorily these 

 two species have failed, and I think they should be united. 

 Mueller first sought to distinguish them by stating (Trans. 

 Phil. Inst. Vict., iii., 59) that //. decurrens "differs from 

 ]] . retusum in shorter more wrinkled leaves, with broader 

 decurrent lines, in neither shining nor glabrous nor heterogam- 

 ous floAverheads, and in more copious pappus-bristles." Later, 

 in Fragm. viii., 46, he adopted another formula: — "Ab 

 77. ret n so distinguendum est capitulis paulo longioribus apice 

 magis apertis, sqnamis involucri minus flavescentibus 

 nunquam laxis." As regards the supposed presence of female 

 flowers in TJ . reiusum and their absence in H . decurrens, out 

 of ten specimens examined only two (from Murray Bridge 

 and Kangaroo Island) had no female flowers, and these two 

 were not distinguishable by any other characteristic from 

 specimens which had both bisexual and female flowers in each 

 head. The leaves, which vary from 5 to 15 mm. in length 

 and are usually spreading, have a narrow groove along the 

 upper surface and a small point which is more or less recurved, 

 so that the leaf appears either truncate or notched at the 

 summit. The upper-surface varies from rough to almost 

 smooth, and the margins are always more or less revolute r 

 sometimes almost hiding the tomentose under-surface. The 

 decurrent lines are often as long as the leaf itself and are 

 always conspicuous, at least below the young leaves, for the 

 prominence or otherwise of the lines is almost entirely a 

 question of the age of the leaf, just as the looseness or 

 otherwise of the involucral bracts is a matter of floral
