Root, stigma, filament veins.

[Pankaj Jaiswal]

Hi Donghui,

Can you give us the PMID/citation of the paper that requires these 
terms. So far my understanding is that vein is nothing but a continuous 
stretch of vascular system, thus it is just a synonym.

However, we would like to go through the paper that refers to these 
things as vein, before making any more comments.
