something growning out of my rock

There are something that looks like 3 blades of grass but much smaller growing in two different patches on my live rock , its not algae or anything like that its some kind of plant , Ive never seen anything like this before , anybody know what it could be? I dont have a digital cam or Id leave a pic.
