Trillium lanceolatum Boykin, S. Watson Proc. Am. Acad. 

 14:274, 1879. 



The only station I have ever found for this rare Trillium is on 

 the western slope of Lookout mountain, in Hamilton county, Ten- 

 nessee. It was growing in rocky soil, in shade. 



Euphorbia mercurialina Michx. Flora 2 1212, 1803. 



This species, which seems to be but poorly known, I found 

 among broken rocks on the slopes of Lookout Mountain, near 

 Chattanooga, Tennessee. I have also taken it on the cliffs of the 

 Coosa river, near Rome, Georgia. 



NYMPHiEA sagitttefolia Walt. Fl. Car. 155, 1788. 



Collected near Fayetteville, North Carolina, the past season, 

 where I found it growing in small ponds together with its more 

 common relative, N. advena Soland. 82 



Gerardia georgiana n. sp. 



While collecting in the pine barrens near Cordele, Dooly 

 county, Georgia, in September, 1901, I found a gerardia which 

 was so strikingly different from any I had seen before that I at 

 once decided it must be new. Later comparisons with herbarium 

 specimens bear out this assumption, and I, therefore, adopt the 

 above name and append the following description : 



Annual, 3-5 dm high : stem obscurely four-angled, minutely 

 roughened, much-branched : branches long and ascending, the 

 lower frequently equaling the main axis in length : leaves linear, 

 i-i.5 cm long, acute at the apex, tapering from below the middle to 

 a slender base, about i mm wide, scabrous above, smooth beneath, 

 the margins revolute : flowers mostly alternate : pedicels stout, 

 erect, about as long as the calyx : calyx campanulate, 2-3 mm long: 

 sepals triangular-subulate, i-i.5 mm long: corolla small, rarely 

 over i cm long, the tube funnel-form or but slightly^ swollen, some- 

 what villous in the throat ; corolla-lobes nearly equal, spreading, 

 rounded, ciliate on the margins : stamens nearly equal, the fila- 

 ments of the longer pair together with the anthers, which are mu-
