Canada Wild Rye, Fort Shaw, Montana

Best I could find in the Montana Field Guides, this is Canada Wild Rye, albeit growing in Central Montana, close to Fort Shaw. 
The opposing curved forms remind me of how horses will stand close, each head to the others’ tail end; if they’re the same colour, the right angle gives view to a single Pushmi-Pullyu. 
(Thank you, Hugh Lofting, for encouraging childhood flights of fancy and unbridled imagination.)
