Heliaxthcs divakicatus, L. 



Our specimens of this species show a wider range of 

 cauline leaf forms than are included in Gray's descrip- 

 tions. They vary from the ovate-lanceolate form, deeply 

 and regularly serrate, to ovate with ohtuse or rounded tips,

 from typical divaricatus — the truncate, sessile, obtuse 

 leaves, not being even divaricate.
