Flower of the underworld

I’m just back from my first sighting of the “flower of the underworld”, Dactylanthus taylorii or pua o te reinga.

This was a Manawatu Botanical Society trip, led by Todd McLay of Massey University, to see a nearby, accessible population.

It was exciting to be shown Dactylanthus taylorii, which is a very odd plant! It is a root parasite, and produces no leaves. A distinctive scar – a “wood rose” – is formed on the host’s root where it is attached. The flowering inflorescences are comparatively large, and can betray the presence of what is otherwise a very cryptic plant. The flowers are bat-pollinated.

Unfortunately, Dactylanthus taylorii has become very rare, because of introduced mammals (including humans), and it is rated as “Nationally Vulnerable”.

I saw a related plant, Balanophora, in Queensland during my field-work there last year.

    I’ve never seen a Dactylanthus flower in the field, so I don’t have my own photos. However, you can see images of flowers at these websites:

    A photo of the flower of the underworld would be good.
