BRENES-PRENDAS, Steven  and  AGUERO-ALVARADO, Renán. Description and distribution of genus Dieffenbachia associated to banana plantations in Costa Rica. Agron. Mesoam [online]. 2012, vol.23, n.1, pp.55-61. ISSN 2215-3608.

Twenty three banana farms were  sampled between 2006 and 2009 for Dieffenbachia species. Field samples were taken to the laboratory for identification. Field distribution and frequency were  recorded and the frequency - cover index  (IFC) was obtained  for  each  species.  Three   species   associated  to banana  plantations  were  found,  Dieffenbachia  oerstedii, Dieffenbachia tonduzii and Dieffenbachia concinna; besides, a  potential hybrid from D. oerstedii and D. tonduzii  was observed.  D.  oerstedii  showed  the  highest  IFC  (40,8%), followed   by D. tonduzii (8,2%) and  D. concinna (0,5%). Currently,  D.  oerstedii  appears  as  the  dominant  species of this genus in banana  plantations in the agroecosystems evaluated.
