Serenna veriformans

Vermiform is a victional plant taxa that is breafly mentioned in Jurassic Park. Upon arrival at Isla Sorna Ellie Sattler sees some Vermiform plants and says they are supposed to be extinct since the Cretaceous period. InGen recreated this extinct plant.

Script quotes
IN THE LEAD JEEP,

Ellie stares off to the right, fascinated by the thick tropical plant life around them. She tilts her head, as if something's wrong with this picture.

She reaches out and grabs hold of a leafy branch as they drive by, TEARING it from the tree.

IN THE FRONT JEEP,

Ellie stares at the leaf, amazed, running her hand lightly over it.

ELLIE

"Alan - -"

ELLIE (cont'd)(still staring at the leaf)

"This shouldn't be here."

ELLIE (cont'd) (still looking at the leaf)

"This species of vermiform was been extinct since the cretaceous period. This thing - -"

Jurassic Park film
The taxa name has been changed from vermiform into vermiforman.

Interpretation
This scene is puzzling for multiple reasons. Why is the script name vermiform changed into vermiforman? It is a bit counter-intuitive that InGen would recreat extinct plants and let them grow in the open fields and let tourists touching it. Moreover, there has never been described a plant taxa name vermiform(an).

The leaf Ellie holds belonges to a species of vermiforman. Indicating that 'vermiforman' is the name of a genus or higher taxa. In which case, it should be written with a capital letter (which isn't the case in the subtitles or the script). The term vermiform usually refers to something that is worm-like, like in Vermiform appendix, not really appropriate for the leaf Ellie holds.

Because the name is made up by David Koepp it can be understood that the stage-manager didn't take much care if the fictional name was pronounched correctly. This could explain how vermiform changed into vermiforman.

This fictional name is maybe chosen becouse a non-existing name was needed. Maybe Ellie was supposed to have discovered and named this new species or even a new group of Mesozoic plants. And veriforman is part of it. That could explain how she got her Ph.D so early and why Hammond includes her as one of the top minds in her field. Such a discovery could have made her a rock star in the botanical world.

Did InGen not only recreated extinct animals, but also extinct plants? It is clear from the quote "this species of vermiform was been extinct since the cretaceous period" that this vermiform species was extinct. In the 'lunch scene' Ellie referse to the fact that these ancient plants are now back and the dangers of that:

The question is - - how much can you know about an extinct ecosystem, and therefore, how could you assume you can control it? You have plants right here in this building, for example, that are poisonous. You picked them because they look pretty, but these are aggressive living things that have no idea what century they're living in and will defend themselves. Violently, if necessary.

Ancient DNA from plants could have been gained from leaf fragments or pollen in amber or from leaf suice that insects had sucked before they got trapped in amber. It is stated in The Lost World novel that InGen had a special facility for breeding plants for the park. Furthermore, recreating plants it much easier than recreating higher animals.
