lanceolate-ovate to crenate, rounded at base. Plant pubes- 

 cent with several-celled hairs. 1. G. pilosa. 

 Corolla at least twice as long as the calyx. Capsule broader, 

 acute to rounded. Pedicels longer. Stem glabrous or pubes- 

 cent with one-celled hairs, these frequently gland-bearing. 

 Corolla within throat on posterior side densely pubescent with 

 knobbed hairs. Capsule ovate in outline, 1-5 mm. long. 

 Seeds .3-.5 mm. long, semi-globose to oblong. Pedicels 

 slender, at least twice the length of the sepals. 

 Capsule 1-2 mm. long, much exceeded by the sepals. Stem- 

 leaves clasping by a broad base, denticulate, usually at least 

 the upper with resinous dots. Root-stocks developed, peren- 

 nial, slender. 2. G.ramosadrummondii. 

 Capsule 3-5 mm. long, about equaled by or longer than the 

 sepals. Stem-leaves narrowed to a sessile or slightly clasp- 

 ing base, obscurely or not resinous-dotted. Roots appar- 

 ently annual, the main root short. 

 Corolla-lobes white, the tube yellowish. Capsule globose- 

 ovate, about equaled by the sepals. Seeds yellowish, the 

 reticulations relatively fine and not making the seed 

 rough in contour. Stems relatively thick and fleshy. 

 Corolla externally glandular-puberulent. Leaves 2-5 cm. 

 long, ovate-lanceolate, serrate-dentate distally. 



3. G. negleda. 



Corolla externally glabrous (apparently). Leaves .5-1-5 

 cm. long, nearly linear, entire. 



4. G. gracilis. 



Corolla goldsn yellow throughout, glabrous externally. 



Capsule ovate-pjTamidal, nearly twice as long as the 



sepals. Seeds brown, the reticulations relatively coarse 



and making the seed rough in contour. Stem thin, not 



fleshy. 5. G. flava. 



Corolla within throat on posterior side pubescent with unknobbed 



hairs. Capsule globose, 5-6 mm. long. Seeds .7 mm. long, 



linear. Pedicels stout, less than twice the length of the 



sepals. Leaves and root as in negleda. 



6. G. virainiana. 



1. Gratiola pilosa Michx. 



Gratiola pilosa Michx., Fl. Bor. Am. 1: 7. 1803. "Hab. in Carolinae inferioris

 all petals. Flowering from June to September, and soon ripening
