obsolete (or adnate to the upper lip?). Capsule linear, either entirely 4- 

 valved, or seedless contracted and entire at the top and sometimes between 

 the seeds. Seeds usually truncate, and more or less angular; testa thick 

 and hard, sometimes almost bony; embryo from half as long to nearly as 

 long as the albumen. — Herbs undershrubs or shrubs. Leaves narrow-linear, 

 entire, scattered or crowded and heath-like. Flowers either solitary and 

 terminal or leaf-opposed or several in compact, leafy terminal corymbs, blue 

 white yellow red or greenish. 



The genus is limited to Australia, aud is readily known as well by the habit as by the 

 indusium, ovary, and fruit-
