 of all known species but one [Anthurium violaceuin) are glabrous, but in other respects 

 very variable, sometimes recalling Spiiri/nuiete (Acorus), sometimes ATarantacea 

 (Aglaonema niarantfcfoliura), sometimes Smilacece (Goniurus), sometimes Taccacea 

 (l)iacunculus, zVmorphophallus), and sometimes even some Dicotyledonous plants, as 

 Aquilarinea (Heteropsis sulicitblia), or Cycadece (Zanioculcas).
