Wow, I was expecting to see leaves -- OK I'm pretty sure these look to me like dried oregano flower stalks but I would be more comfortable if there was a size scale/reference -- you may be able to obtain seeds if they had matured and have not been scattered already. If you crumble and sniff, you should be able to detect characteristic aroma of thyme or oregano.
I'm not sure what the rest of the question means. If you mean can we tell species or cultivar from these, I kind of doubt it?
