 P.fiexilis, approaching by its short cones close to P. Cemhra. The large 

 seeds of P. fiexiUs are, as Dr. James already stated and as Dr. Hayden 

 confirmed, eaten by the Indians. They are distinguished from those of 

 any other of our Pines by a persistent, sharp, keeled margin, representing 

 the wing.

 Jbkaulis and (E. pinna ti/da. In Plantce Wrightiance I had come to 

 the. conclusion that Pursh was right, not then knowing the seeds of (t. 

 pinnatijida, Nutt. Consequently, when good fruit of the latter came to 

 hand, in Wright's second collection, in Pi. Wright, 2, p. 56, I carelessly 

 referred the specimens to (E. coronopi/olia, on account of their seeds, not- 

 withstanding their longer capsules, overlooking the other character, and 

 wrongly supposing that Nuttall's description of the seeds of his (E.pif- 

 natifida or Bradburiana somehow belonged to (E. coronopifoUa, which, 

 as 1 had shown in PI. Fendlerian*, has such seeds, while those oi(E. «'- 

 hicaaUs are longer and smooth. Dr. Engelmann has recently corrected 

 this oversight, and in the following memorandum has established the three 

 species upon a good foundation. I greatly doubt the distinctions based 

 upon the duration of the root, although CE. albkaulis and CE. coronopj^ 

 lia generally, if not always, have the appearance of being perennial, while
