Apply HMM on iris dataset?

can some one show me how to apply hidden markov model on iris dataset. I was just going through when looking for hmm on real world datasets. If someone could explain me step by step as of how the data needs to be fetched to make predictions it would be of great!

Note: I know about the three problems related to HMM well enough. I am looking for how to apply hmm on large dataset say iris. What i am thinking is to use the sepal width alone to predict the species of the flower. Am I correct ?

PLEASE help. Thnx
