Tj^pe, Biltmore, North Carolina, collected in flower August 27, 

 1897, Biltmore Herbarium 481; in United States National Her- 

 barium. 



Dry oak or mixed woodland, on mountain-slopes, eastern and 

 western Appalachians, from southwestern Virginia and southeastern 

 Kentucky to northern Georgia. 



This differs from Aureolaria pedicularia amhigens (Fernald) Far- 

 well of the southern Lake region in its leaves narrower, more deeply 

 and sharply cut, and its calyx-lobes longer and more deeply lobed. 



Pennell (Tennessee) — 5725. 



2. Aureolaria pectinata (Nutt.) Pennell. 



Gerardia pedicularia pectinata Nutt., Gen. PI. N. Amer. 2: 46. 1818. "Hab. 

 In the sandy pine forests of Carolina and Georgia." Specimen of Nuttall's 

 collecting in the British Museum, labeled "Gerardia millefolia S. Carol.?" 

 may represent the type. It is determined by Dr. S. Moore as the form 

 now considered, agreeing with my number 5638 from Louisiana. 



Aureolaria pectinata (Nutt.) Pennell, Bull. Torr. Bot. Club 40: 414. 1913. 



Dry sandy pine and oak lands, especially hilly, through the Coastal 

 Plain from South Carolina to northwestern Florida and Louisiana; 

 extending inland on sandy soils (as the granite of central Georgia), 

 to westernmost North Carolina and eastern Tennessee, and through 

 the Mississippi Valley westward in our area. Ranges northwest- 

 ward to Kentucky and southern Missouri. The inland forms have 

 larger leaves and fruit, and probably represent several geographic 

 varieties, an enumeration of which will be given in the writer's 

 "Agalinis and Allies in North America." 



Flowering from July to October, fruiting in September and Oc- 

 tober. Corolla yellow, externally more or less tinged with reddish, 

 within not marked with purple -red.

3. Aureolaria virginica (L.) Pennell. 



Rhinanthus virginicus L., Sp. PI. 603. 1753. "Habitat in Virginia."

Aureolaria villosa Raf., New Fl. Amer. 2: 59. 1837. No type locality
