This species is nearly allied to C. straminea; but may 
readily ra distinguished from it by its shorter, more round, 
and less widely winged fruit, and , its scale, which is 
ovate-lanceolate and mucronate. e scale of C. strami- 
nea is lanceolate or oblong-lanceolate, and its fruit less di- 
verging than that of this species. From C. scoparia and 
Cc. ~~ it is readily distinguished by the eharac- 
ters already given
