232 CONTRIBUTIONS TO THE FLORA OF AUSTRALIA, 



Acacia Maideni, F.v.2I. — -A quantitj^ of fresh fruiting material 

 of this species has recently been examined by me, and from my 

 observations it would appear that an error has occurred in the 

 delineation (mei) and description (F.v.M.) of the arillus, in the 

 Macleav Memorial Volume. Our collector now admits having 

 inadvertently wrongly matched the pods. Those figured are from 

 A. melanoxylon, R Br. The true seed has a much shorter arillus 

 under it and not encircling the seed at all. It has only two or 

 three short folds. A strict examination, however, revealed 

 nothing to shake its specific rank. The fruits and seeds are quite 

 distinct from those of A. fjlancescen,^, its all}^

For the identification of this species I am indebted to J. G. 

 Luehmann, F.L.S. The only locality given in the Index Kewensis 

 (Vol. i. p. 183) is New Caledonia, so that it is therefore new for 

 Australia. In the above reference Forster is quoted as the 

 author, and it is very probable that it was on this species that 

 the genus was founded (Forst. Char. Gen. 30). Bentham, how- 

 ever, ;^^.^7. ii 437) ascribed the authorship to Labillardiere, but 

 I should like to venture an opinion that A. eUipticum is what is 

 intended (vide Index Kewensis, Vol. i. p. 183). 



There is apparently no description of this species extant. It 

 is a very pretty shrub of about 20 to 30 feet high The branches 

 and inflorescence are clothed with a close silky white tomentum 

 more silvery than in A. Lejourdanii, F.v.M. Leaves ovate, 

 acuminate, varying from 4 to 7, 8 or even 9 inches long and up 

 to 2 inches broad, on a petiole of \ inch long or more, entire or 

 serrate, light green and glabrous above, silvery-white underneath 

 with a close silky tomentum, the pinnate parallel veins and 

 midrib not prominent on the upper surface.

 from New South Wales.
