Yes, male flower. Even if it does shed pollen, there will not be enough time for seeds to grow and if they did, they would be female seeds. This is a last ditch effort by your plant to reproduce and is common in older unfertilized females. For pictures of what they will grow into, go to my Sweet, Sweet Seed #3 diary and pictures 29, 30 and 31 will show you.
Unless your plant is infested with them, there is no real need to do much, but it is probably safer to remove any you see. They are still 2-3 weeks away from being able to release viable pollen and then it takes another 4-6 weeks for the seeds to form, so unless you are more than 6-9 weeks away from harvest, I wouldn't stress too much. Just pick them out as you find them and all will be well. If you are really keen, you could let one grow until it sheds pollen, fertilize a flower or two and this will stop your plant from producing any more male flowers. This is due to the plant "recognizing" a change in hormones associated with seed growth and this will "tell" her there is no more need to produce male flowers, as success has occurred and seeds are being made.
These sneaky male flowers are also the reason why one or two seeds show up in plants that were nowhere near any males at any time. Isn't cannabis so clever!
