[Po-dev] Re: Peripheral vein vs tertiary vein or high order vein

[Chih-Wei Tung]

Hi Alejandra,

Thank  you for quick reply.
I also found a review paper "Evolution and Function of leaf venation  
architecture", it has a  "brochidodromous venation" picture (see pdf  
attachment). I will also look into those papers you mentioned here.

One thing I am puzzled is the photo has a pink highlight at the  
peripheral region, it's likely AGRON-OMICS are interested in that  
particular structure (peripheral vein), do you know if there is any  
specific terminology to describe such joined vein structure? Can we  
call it "brochidodromous vein" ?

Thanks,

Chih-Wei
