be deemed a subgenus of the last if liked, but 

 is very distinct and may as well be a Genus. 



368. Panctenis peok ularis Ilaf. (or Au- 

 reolaria) Gerardia do L. <fcc. Well known 

 common species very branched and clammy 

 villose, segments of calix crenate serrate or la- 

 ciniate. Var. 1 ramoslsshna, 2 pumila, 3 

 simplex ^c, but 2 other varieties appears to 

 be wide deviations and incipient sp. sprung 

 from this. 



369. Panctenis pectinata Raf. Ger. pedic. 

 var pectinata Nut. leaves ovate pectinatly sub- 

 bipinnatifid softly villose, peduncles short, seg- 

 ments of calix pectinate — found by Nuttal in 

 pine woods of Carolina, by myself in pine woods 

 of Alleghanies, sesquipedal. 



370. Panctenis pumila Raf. dwarf, leaves 

 lanceolate, crenate or pectinate hardly pinnati- 

 fid, petiols elongate, segments of calix only cre- 

 nate — Alleghany Mts. found in bloom later than 

 any other in Autumn, roots large thick branch- 

 ed, stem only 3 inches high, leaves small not 

 bipinnate, flowers as large as usual, whole plant 

 quite hairy but not clammy. Could it be a late 

 Autumnal shoot thus deviating to form a pecu- 

 liar species ? 



371. AGALINIS Raf. (remarkable flax.) 

 Calix campanul. 5 dentate, often truncate, teeth 

 subequal not obliqual. Corolla widely cam- 

 panulate 5 lobes rounded equal obliqual often 

 ciliate. Stamens didyn. villose, anthers bicus- 

 pidate at base, dehiscent lateraly. A style, 

 stigma obtuse compressed. Capsule globose 

 bilocular, bivalve quite split, polysperm. Chie- 

 Jly annuals^ slender stems and leaves, floic- 



ers axillarii and terminal purplish — a very 

 distinct natural Genus having the habit of flax,
