Apparently Gratiola ramosa Walt. (Fl. Carol. 61. 1788) in- 

 cludes two incipient species to be distinguished as follows: 



Capsule usually wider than long. Sepals more than twice as long 

 as the capsule, usually subtended by one or two sepal-like bract- 

 lets. Stems 2-4 dm. long, more laxly ascending, its leaves 

 usually 1.5-2.5 cm. long. Plant usually less fleshy. South- 

 western Georgia and northcentral Florida to Texas and Okla- 

 homa. G. ramosa drummondii. 



Capsule as long or longer than wide. Sepals usually about twice as 

 long as the capsule, subtended by one small bractlet or none. 

 Stems 1-2 (-3) dm. tall, strictly erect, its leaves usually less 

 than 1.5 cm. long. Plant more fleshy. South Carolina to South- 

 ern Florida, and, occasionally, westward to eastern Louisiana. 



G. ramosa.
