6. SCROPHULARIA.

Calyx in 5 acute segments ; corolla subglobose, limb contracted, 

 sub-bilabiate, lip with an internal, intermediate scale (sterile filament) ; 

 capsule 2-celled ; valves with 2 inflated margins. — Herbs or suffruti-

 green scale (sterile filament) adnate to the upper side. July— Oct.— The plant 

 is quite variable in the Ibrm of the upper leaves and in the development of the 

 panicle; but having observed it in numerous localities in the Middle and
