During the 2013 field season I was hoping to find Hyobanche thinophila in West Coast National Park. I had previously predicted the distribution would go as far as the dune fields near Langebaan.  We searched the dunes for two days. On the second of those days, I found a stand of Metalasia, which, in my mind, meant good Hyobanche thinophila territory.

After climbing up this steep dune, my prediction panned out and I spotted a lovely pink dot amidst the Metalasia growing on the side of this active dune.

It was a very welcome sight, indeed.

The rhizome extends several meters into the dune. This is a lovely morphology, in my humble opinion.

Dissecting the flowers for photography was one of my objectives during the field season. I didn’t have a ruler with me, so a two rand coin is there for scale. The calyx morphology is a little different than what I drew in my description of the species. The calyx is more deeply divided to nearly a 2+2+1 configuration of the sepals.

The manuscript with the species description is available here:
