 Let it be remembered that these discoveries of 

 Kin and Baldwin had been made 20 and 30 

 years ago, laying dormant like those of Bar- 

 tram in herbals. 



POLYGONUM and akin Genera. 

 This Genus the shame of botanists as be- 

 longing to 10 linnean classes ! was illustrated in 

 my flora tellur. 401 to 434. I have described 

 there many N. Amer. sp. and the new Genera 

 Tracaulon, Spermaulaxen, Stopinaca, Ante- 

 noron, Tovara, Pleurostena, Chulusium, 

 Peutalis SLC. 1 shall merely add some other 

 remarkable new species formerly included in 

 Polygonum and Rumex divided also in 7 Gen-

 about 100 sp. of these G. akin and reformed, I 

 may yet revise the whole. 



848. PEUTALIS or MITESIA LIGULARIS Raf. 

 smooth filiform, leaves lanceolate acute, sessile 

 sheaths simple obsolete, racemes axil, and ter- 

 minal filiform pauciflore,flowers remote, sheaths 

 tubular ligulate obtuse equal to pedicels. A 

 curious little species, half pedal, deemed Polyg. 

 mite by Collins, very different, leaves few uncial 

 quite smooth, racemes with 3 to 7 flowers, each 

 out of a singular sheath, calix incarnate 5lobed 

 seeds lenticular. Apalachian Mts. of Carolina, 

 Iron Mts. found by Lyons ? Mitesia may be a 

 subg. of Peutalis, this appears a Peutalis by 

 seed, I cant count the stamens usualy 6 in Peu- 

 talis and Mitesia, but with 3 styles and trigone 

 seeds in Mitesia. 



849. PEUTALIS or MITESIA FLORIDANA Raf. 

 Polyg. N. sp. Baldw. smooth erect simple,leaves 

 sessile narrow lanceolate nearly obtuse margin 

 rough, sheaths tubular bristly, flowers in a sin-
