Not one I saw down in the SW on this trip, but I’ve somehow never discussed it before despite haven’t photographed this one in the Goodale Reserve SE of Perth, a few years back. It’s possible the Tumblr Purge ate the post, though.
Like other Duck Orchids, this species only ever grows a single small leaf, but unlike those, the leaf is still unwithered at the time of flowering. It grows in clearings in woodlands and scrub, between Perth and Albany. Hort's duck orchid was first formally described in 2006 by Stephen Hopper and Andrew Brown who gave it the name Paracaleana hortiorum, but in 2014, based on molecular studies, Joseph Miller and Mark Clements transferred all the Paracaleana species back to Caleana. The specific epithet (hortiorum) honours Jean and Fred Hort who were early collectors of this plant (and happen to be acquaintances of mine).
