8. EUNANUS, Benth. Annuals, either dwarf and depressed, or erect 

 and somewhat strict. Herbage glandular-hairy and somewhat viscid. 

 Flowers axillary and solitary. Calyx prismatic, 5-angled, 5-toothed.

 sule from cartilaginous to almost membranaceous, but dehiscent on one 

 side only, or from that to a little below the apex on the other side, 

 obtuse and shorter than the calyx, or acuminate and surpassing it.
