MONOECIA TRIANDRIA. 6'^ 



\^lved, the valves compressed, hairy along the 'midrib, conspicuous when 

 young almost concealing the fertile florets; corolla two-vaK ed, valves very 

 minute, slender; of the stamen, styles, or nectary, scarcely a vestige. Fer- 

 tile florets sessile, two-valved, exterior valve orbicular, cartilaginous, entire, 

 ([not emarginate at the sides,) corrugated by irregular transverse ridges, the 

 interior oblong, firmly attached to the rachis; corolla two-valved, valves 

 equals membranaceous; nectary one? leaved, very small; stamens three, ex- 

 serted; styles two; stigmas feathered. Seed one, round, enveloped by the 

 persistent calyx. 



It appears to me somewhat doubtful whether ^this plant and the M. Myu- 

 rus of India are really congeners. 



I am not certain whether this plant is really indigenous, or has been intro- 

 duced from the West Indies. I have only seen it around Charleston, where, 

 however, it is ver}^ common in dry pastures. 



Flowers August — October. .
