 — Florida, erect smooth, leaves uncial, flowers 

 and silicles very small but profuse. t

 Dec. &c. — Ohio. This G. although shown to 

 Torrey in 1826, has not been admitted by him, 

 and merely noticed as doubtful. It is near the 

 last G. but the silicle is shorter not nervose, 

 stigma entire, petals yeliow. t

 Florida. I have revised this sp. to contrast it 

 with the next. This curiuos G. does not bebng 

 to Scrofularides ; but is very near Veronica, 

 differing by habit like Scleranthus, corolla equal 

 and 4 stamens, are they opposited ? when it 

 would be of family Primulides.
