Calgary engineer believes he's cracked the mysterious Voynich Manuscript

[Ruby Novacna]

SEMSEM (SEM SEM) is the name of a plant. 
I have not been able to find the Latin version of this plant...

If it's a Turkish name, it must be easy to find, I think. 
Or is it an Arabic name for sesame?
P.S. I didn't understand which page this word is on?
