Added some information about how the Nijnhuis tensor obstructs the existence of pseudoholomorphic mappings
Jun 18, 2014 at 8:20 comment added Robert Bryant Unfortunately, I don't know any specific references where this is discussed in detail, but there's nothing deep about it. I'll add some remarks to my answer above that may be helpful.

Jun 17, 2014 at 14:27 comment added Ritwik @Bryant: Thank you... I should have thought about the example you just gave with the identity map! Can you give a reference where I can read a bit more about the second thing you said (non vanishing of the Nijnhuis tensor sometimes implying that any pseudo holomorphic map is constant)?
