 Found in flower by H. H. D. Griffith on the edge of swamps near 

 Cape Borda and Starvation Creek, Kangaroo Island, October, 1908. — 

 This is a very distinct species, standing nearly midway beetween Bo- 

 ronia and Zieria. It has the thick, entire disk of the former genus, but 

 only the 4 stamens of the latter. It has been decided to place it in 

 Boronia, on account of the undivided disk, the collateral ovules, and the 

 filaments ciliate for three-fourths of their length, and glandular at the 

 apex. The two firstnamed characters are never found in Zieria, and 

 ciliate filaments are rare in that genus. In habit the new species clo- 

 sely resembles B. parvifiora Sm., but is distinguished from that and al 

 other Boronias by the 4 stamens, and from most of them by the sepals 

 being longer than the petals.
