304 XXVIII, B-UTACE^. - - IZleria. 



Disk with 4 distinct gland-like lobes, alternating with the petals. Stamens 

 4, inserted on the outside of the glands of the disk. Cai-pcis 4, distinct or 

 nearly so ; styles nearly terminal, short and united at least at the top ; stigma 

 capitate, 4-furrowed or shortly 4-lobed. - Ovules 2 in each carpel, supeq^osed. 

 Cocci 4, 2-valved, the endocarp cartilaginous and separating elastically. Seeds 

 solitar}% or rarely 2 in each coccus, oblong; testa crustaceous. — Shrubs or 

 rarely small trees, glabrous hirsute or tomentose. Lf^aves usually opposite, 

 with 3 leaflets, rarely alternate or simple. Flowers white, usually small, axil- 

 lary, in small tricliotomous cymes or rarely solitary. 



The species arc all cudcTnic in Australiaj and F. Mueller considers tlicin as forming a 

 seclion ouly of Boronia ; but the charuckrs and habit appear to iiic sufficicatly distinct to 

 justify the maintenance of so old-established and generally adopted a genus.
