Most certain plant ID's?

[Koen G]

F33v, Helianthus annuus.

You bully 

JKP: The heliotrope example does illuminate quite well the problem we are facing, although based on the images you provide I'd say the VM leans more towards naturalistic depiction of the fern.

It's the first time I hear about some of the examples you list, while others I've heard before. Let's see, I'll cross-check with the You are not allowed to view links. Register or Login to view. of old ID's at Rene's site:

• Knapweed for f2r seems about as universally accepted as you can get.
  
• Tragopogon for f65v, there Rene's list gives chamomile among others. Maybe it's not so clear?
  
• For Cannabis/hemp, do you mean f16r?
  
• Cuscuta/dodder for f49r: seems reasonable to me, I'll include it unless there are objections.
  
• Castor oil seems almost certain to me, especially since I saw its image in the Trinity herbal. Also general agreement in Rene's list.
  
• Althaea: which folio is this again? I can't find it or marsh-mallow in Rene's list.
  
• thyme and portulaca: which ones are those? 
  
• For You are not allowed to view links. Register or Login to view. they give Smilax, Tamus communis (= Dioscorea communis, black bryony). Especially the latter seems like a decent possibility as well?
  
• Spigelia seems like a very good match for the leaves of f15v, but isn't this an American plant? Also, the VM plant has one large flower bud from which two protrusions emerge, this seems different than the many flowers of Spigelia (although the appearance is similar).
  
• Your You are not allowed to view links. Register or Login to view. agrees with Rene's list, I'll add it.
  
• They are giving a ton of possibilities for You are not allowed to view links. Register or Login to view. , all apparently based on the shape of the leaf (like mint). 
  
• f18v malva: seems like a decent match, I'll add it until someone shoots it down
  
• for You are not allowed to view links. Register or Login to view. Rene's list contains prunella vulgaris as well but also mint. If you look through the green paint, you see that the leaves are actually slightly serrated. Maybe more like mint? Although upon closer inspection slightly lobed edges are more like prunella after all.
