Is there a suggestion of a square stem towards the top? If so, it may be H. tetrapterum. Difficult to tell, it may just be the two raised lines I am seeing.

I suspect it is at least one of the two raised lines. The leaves don't look right for H. tetrapterum.
Thanks. I was with you really...it was only a thought!
