Most certain plant ID's?

[Koen G]

Following the water lily thread, I wondered: which plants in the VM can be identified with an above average degree of certainty and consensus? Note that I don't say complete certainty and consensus since both are unlikely. Also, I don't mean specific subspecies (that's not the right question to ask) just general plant type. Let's say as specific as possible without straying too far into "maybe" territory.

Edited list so far (proposals where there appears to be especially great agreement are in bold):

• f1v Belladonna, Deadly nightshade
  
• f2r Centaurea (subspecies uncertain: knapweed, cornflower...)
  
• f2v Water lily
  
• f5r paris quadrifolia 
  
• f6v Ricinus (castor oil plant) 
  
• f9v Viola 
  
• f16r Cannabis 
  
• f17v tamus (dioscorea)
  
• f18r Calendula / Mountain aster 
  
• f18v Malva (JKP)
  
• f21r Polygonum Aviculare, a Herniaria species or similar plant. The drawing is broadly considered lifelike, but there are too many plants that look similar. See You are not allowed to view links. Register or Login to view..

• f25v plantago 
  
• f26r Sedum telephium (JKP)
