pssh command with host name

Question

I need to execute a comand in parallel in several machines. this can be done with pssh: parallel-ssh -h hosts.txt -l ubuntu -i echo "hello, world"

this is ok when the command doesn't require the hostname in the parameters. But what if the command need the host name to run like this: my_obscure_cmd --host 10.11.xxx.xx

How can i run this command with pssh?

Any help would be appreciated.
