DIANDRIA. MONOGYNIA. 3

 Cal. 5 parted. Cor. tubular- campanulate; border 4 lobed, unequal. Caps, ovate, acuminate/, 

 L. viRGimCA. Bart. Fl. Phil. Stem erect; leaves verticillate; spikes terminal, long. 

 Sunon. Veronica virginiea. Auctorum. Vulgo— Till Veronica. Virginian Speedwell. 

 FL Middle of July, and after. Fr. mat. Latter end of September. 



Hub. Low grounds, and borders of woodlands: frequent. 2 to 5 feet high: flowers white. 



Obs Mr Nuttall, who separated this from the foregoing genus, remarks that the leaves are " nev0 sim- 

 ply opposite, or ternate;" but I have several specimens with the leaves altogether ternate. 



7. GRATIOLA. Nutt. Gen. 14. 

 [Lat. Gratia, grace, or favor; on account of its supposed medical virtues.] 



Cal. 5 parted. Cor. tubular, resupinate. Slam. 4, 2 sterile. Caps, dissepiment contrary to the valves; 

 G. viRGiNiCA. Ell. Stem assurgent, mostly terete; leaves oval-lanceolate, attenuate at base, toothedv 

 FL Beginning of June, and after. Fr. mat. Last of June, and after. 



Hub. Low, muddy places; ponds, &c. frequent. 4, to 10 or 12 inches high: flowers yellow, or dirty white. 

 Obs. There is considerable variety in the appearance of this plant; and, I think, some confusion and 

 obsnuritv in the descriptions of it. I submitted my specimens to Mr. Schwemitz, who thmks they are all, 

 probably, mere varieties of G. virginiea; although the stems, in some mstances are subtetragonous, and the 

 peduncles nearly as long as the leaves. One specimen from the forks of Brandy wme, flowenng as late as 

 October, {tube yellow, limb white, with a linge of red,) Mr. S. thmks is the G. carolmtana, of Le Conte, 

 but in its general features it resembles the others.

Hub. Low, swampy grounds: Patton's ; Brandy wine : frequent. 4 to 8 inches high: flowers pale blue. 

 nh. This plant closely resembles Gratiola, in habit. The capsules in my specimens are gm/e as long 

 ?h P.lrl ■ f See Parsh ) and in no instance is the peduncle " longer than the leaves." (bee Elltott.) Yet 

 I have the auOiority of Mr. Schweinitz for the above designation. 



9. CATALPA. Nutt. Gen. 16. 

 [A name said to have been derived from our Southern Indians.]
