 times exceeding the tube : corolla light blue, an inch or more long, its broad and roundish 

 short lobes erect, little and often not at all longer tlian the 2-cleft and many-toothed inter- 

 vening appendages: seeds nearly as in the preceding. — Spec. i. 228 (Moris. Hist. iii. 484,

 lobes laneeclate to ovate, usually sj)reading or recurved, shorter than the tube: corolla as 

 the preceding but more oblong and the lobes obliterated or obsolete, the truncate and 

 usually almost closed border mainly consisting of the prominent fimbriate-dentate inter- 

 vening appendages: seeds with a conspicuous wing, oblong in outline. — Gent. 287, & in

 or subcordate, acute, reflexed-spreading, shorter tlian tiie tube : corolla dull white and 

 commonly tinged with yellowish or greenish, often an inch and a half long, like that of 

 G. Saponnrin, but more campanulate and open ; its ovate lobes twice the length of the 

 broad and erose-toothed api)endages. — Cat. ed. 2, 29, & Fl. Lancast. ined. ; Nutt. Gen.
