I've found the author of Voynich manuscript. He was Giovanni Aurispa.

[Rustandi]

There is no name in the page because the name welwitschia mirabilis itself were given in around 18th century. My conclusion about the name based on the description in my translation. Yes the picture ( from bi3mw ) is the plant Welwitschia mirabilis, but i think you could post a much better picture. 

I almost forget I have not answered question from bi3mw about the ciphers. I did it manually without computer software or AI.
