NOTES ON ACACIA. 241 



Attention may be invited to the tendency of the flower- 

 heads to be oblong in the type. 



The Cowcowing specimens (1030) are inequilobed (as 

 regards the calyx) but not so much so as the type. 



The Kellerberrin specimens are in fruit, which may be 

 described as follows, as the fruit has not been previously 

 described. Straight or slightly curved, 5 or 6 cm. long 

 (but not fully ripe), 5 mm. broad, margins slightly thickened, 

 moniliform. Seed (not quite ripe), longitudinally disposed, 

 with a broadish funicle once or twice folded terminating 

 in large grauular basilar arillus. 



Affinities. 



1. With A. genistoides A. Ounn. Mr. Fitzgerald's own 

 unpublished remarks are "The foliage and general appear- 

 ance are those of specimens of A. genistoides. It differs 

 from that species in the bracteate peduncles, conspicuous 

 differently shaped bracteoles, fewer mostly 4-merous flowers 

 in the heads, markedly distinct calyx, and broader thin, 

 unribbed petals." 



2. With A. Prainii n. sp. It is not necessary to fully 

 repeat the remarks under A. incequiloba at p. 240. The 

 two species present considerable resemblance, but the 

 inflorescence is racemose in A. Prainii and the flower-heads 

 globular, while they are slightly oblong in A. incequiloba,, 

 which also possesses leafy bracts, and also long black hairs 

 on the petals, neither of which characters occurs in A. 

 Prainii. 



Uninerves (Triangulares). 



IV. Acacia Rendlei n. sp. 



Frutex spinosus, glaucus, 2 J' altus; phyllodiis sub-triangularibus 

 vel irregulariter trapeziformibus, ca. 7 mm. longis, apice ca. 7 mm. 

 latis, phyllodiis plerumque spinis tenuibus, flexibilibus, brunneis, 

 stipularibus ca. 1 cm. longis suppletis; phyllodiis duobus nervis
