290. PHUYMA PUBESCENS Raf. pubescent, 

 leaves subsessile ovate or elliptic, subcordate 

 acuminate ciliate unequally crenate, last pair 

 entire, bracts subulate equal to calix Allegha- 

 ny mts. pedal, flowers purplish.

 leaves difforme lower petiolate ovate base acute 

 deeply serrate, upper sessile ovate often en- 

 tire, bracts equal to calix the most common 

 kind, from New York to Carolina, 1 or 2 feet 

 high. If all the above are mere varieties of 

 this, they afford a fine illustration of incipient 

 species forming under our eyes in our woods. 



293. THECANISIA Raf. a N. G. of Spi-

 Fruit 1 to 5 thecas unequal stipitate oblong 1- 

 3seeded. Herbaceous perennial plants with 

 lobed or palmate leaves subpinnate, stipulate, 



flowers paniculate. The essential character

 the last 71obed, lobes lanceolate doubly serrate, 

 panicle cymose compound from Carolina to
