This thread of photos of Crocus seeds - mostly photographed on a 1mm scale graph paper - are compiled from the SRGC "Seed Identification : photos of named seed varieties" (http://www.srgc.net/forum/index.php?topic=4426.0)project , many of them taken by Tony Goode, some by Armin Ruby as well as from a new set of pictures taken by Wim Boens of the Crocus Group.
Where there were photos missing from either set, these have been added to the appropriate page.

Ruben Billiet, who helped Wim Boens with the packing of the CG seed for their seed exchange, made these comments in the VRV (Flemish ) Forum (http://www.vrvforum.be/forum/index.php?topic=1354.msg69026#msg69026): =
" When preparing the orders of the seeds for the Crocus Group both Wim and I were very surprised at the diversity of seeds. Even within a species (eg. Goulimyii) seeds could have a very different appearance. (Maybe that may denote a hybrid - or just variability?)
As we worked on this project packing seed for the Crocus Group, Wim had the super idea to photograph the seeds as we went went along. In the future Crocus may possibly be determined on the basis of the seeds.
Classification criteria that were striking: Shape + diameter: perfectly round, large seeds (hadriaticus), huge or small seeds (sieberii), sickle-shaped seeds, spear-shaped ...
Color: Satin red, black, brownish - never white.
Smell: some seeds had a very specific hay-like odour , most were odourless.
(I hope if I have made errors in translation the Wim or Ruben will help me out!)

Are those pictures made from seeds sent to seed-exchange or they are from your own plants?

Janis,
they were from seeds sent to the exchange.

May be this is reason why seeds of some species from various sources looks different. Quite often plants grown from seed exchange seeds turns incorrectly named. Usually Crocus seeds are quite uniform and their shape, size, colour, surface structure are quite characteristic to species.

That is of course a possibility, Janis. Those with varying seeds within the same species were not included in the pictures since I wasn't sure if they were rightly named.

Janis might be right, that sometimes wrong seeds are included in a seed exchange.
But it must not be done with bad faith of the donors:
I remember that I noticed the seeds of speciosus (bright red) and speciosus
Albus (brownish-red) look totally different, same with Crocus chrysanthus
(bright red) and chrysanthus Afyon (dark red) - sorry, I don't have photos.
Later I have learnt from Helmut Kerndorff, that the seeds are also a valuable
feature to distinguish different species.
Meanwhile it has turned out, that the Turkish 'ex'chrysanthus plants really are different
species, and I think, that the plants in trade sold as speciosus Albus (from the Caucasus)
could also be another species....
