Found this pic on another forum but my plant has several of these to could anyone please tell me what these are?

 

[Phytoplankton]

Those are caylxes, female parts, a bud is made up of hundreds of them! You often see them at the nodes before true flowering starts. The two brown things sticking out of it are shriveled pistils.
