3 anthers on very short stamens

As the stamens are very short and anthers totally enclosed by palea and lemma I wonder if it is self pollinated.

Am asking it just out of curiosity as I am totally ignorant about grasses.

During anthesis (flower opening), the lodicules will push the lemma and palea apart and the stamens will elongate and the anthers will protrude out of the floret. The stigmas of the same floret matures at a different time. Thus cross pollination is favoured.

Dear Manoj Ji,

Many thanks for your kind explanation.

So far in spite of my best efforts I have yet to see a spike in which flowers have undergone anthesis and have protruding anthers. Perhaps it is still early. I will keep looking and if I find one I will post a photo.

With sincere regards
