Rhamnus (plant family Rhamnaceae) sect. Cervispina

Mon Jun 3 16:56:52 CDT 2002

We have collected a number of specimens of Rhamnus sect. Cervispina (mostly
Asian -- R. cathartica and related species) growing as escapes from
cultivation in our area (central Iowa, USA). Can anyone suggest either keys
to the species in this group besides those in Rehder (1947) or Swink &
Wilhelm (1994), or a specialist whom we might contact?

With many thanks!
