various height, more or less completely anatropous; micropyle 

 extrorsely inferior, sometimes somewhat lateral. Fruit coriaceous or 

 crustaceous, oftener 2-coccous ; cocci separable, dehiscing longitudi- 

 nally within or at the apex, sometimes circumscissous at the ,base

 nerved or subrectinerved ; stipules connate with leaves in variously 

 setose sheath ; flowers in cymes or compound axillary or terminal 

 capituliform glomerules, variously bracteate, sometimes involucrate, 

 more rarely (Octodon) intermingled with scales perceptibly thickened 

 at the base and ciliate. (All warm regions.) — See p. 262.
