subsp.  C.  byzantina  DC.  Prodr.  VI,  453  (1837). 
Boissier,  1.  c.,  coiisiders  C.  hy.zantina  DC.  as  a mere  synonym  of 
C.  arvensis,  saying,  that  it  was  fouuded  upon  a „specimen  autumnale 
induratum,  nec  suffruticosum,  caeterum  a typo  nullo  modo  distinctum.” 
My  father’s  plant  in  other  respects  agrees  well  with  the  type  of  C. 
arvensis,  especially  with  regard  to  the  shape  of  the  achenes,  but  the 
specimens  seem  to  be  perennial  and  are  distinctly  woody  at  the  base 
of  the  stems.  I have  seen  in  the  herbaria  several  such  specimens 
of  C.  arvensis  from  Central  Europe,  as  Boissier  alludes  to  mth  the 
words  just  quoted,  but  the  Armenian  plant  is  distinctly  different 
from  them.  Besides,  my  father’s  plant  was  collected  already  in  May, 
so  that  the  induration  of  the  stems  cannot  be  an  autumn-phaenomen. 
Probably  C.  hyzantina  must  ba  considered  as  a perennial  subspecies 
of  C.  arvensis.  The  original  locality,  where  De  Candolle’s  type 
was  collected,  is  Constantinople ; the  further  distribution  of  our  plant 
ought  to  be  examined  in  larger  herbaria. 
Near  Trebizond,  floweriug  in  May,  1878.
