brochidodromous can form from secondary vein anatomoses in most cases, but in some, such as some species of Gnetum, it forms from anastomoses of tertiary veins and/or/a combination.

Hi Alejandra,
One more question, does this term " rochidodromous arch" only specific to secondary vein or can be used in any vein order?

Hi,
More than brochidodromous vein it is a "brochidodromous arch".

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

Hi Chih-Wei,
For many years paleobotanists have used leaf architecture as one
tool to describe leaf remains.
There are several papers that address the leaf vein architecture
terminology (Dilcher 1973, Hickey 1974 and more recently LAWG 1999).
What the photo is showing is considered to be the typical
brochidodromous venation (secondary veins joined together in a
series of prominent arches).
If you want the papers I mentioned, I can send them to you

Dear PO developers,
We recently got a request from AGRONO-MICS group regarding to the
term " peripheral vein: a vein located toward the margin of the leaf
lamina" (see attached picture).
Pankaj raised a issue about how peripheral vein differs from tertiary
vein or high order vein, it is very tricky to determine the vein
orders when the veins form a continuous structure at the proximal
ends. If you have any thoughts about this structure, please share
wit us, we would like to resolve it as soon as possible.
Best,
Chih-Wei
