#2718 - Orobanche minor - Common Broomrape
Bit puzzled that I don't seem to have covered this species before, since it's extremely widespread and a common sight here in Perth, too. I've posted photos of it before, certainly. Possibly the original post got eaten in the Great Tumblr Purge for no good reason.
AKA hellroot, and clover broomrape.
A parasitic plant native to Europe, N. Africa, and Macaronesia, but now found everywhere else that's warm enough. It parasitises plants in the pea and daisy family for the most part, but is known to attack plants in many other famiies as well - in the photo above it's probably sucking the juices from the thistle next to it.
Flowers red-brown, yellow-brown, yellow, or purple.
One of almost 200 in the genus, and by far the most widespread. It's the only one that's made it to New Zealand, where it has been naturalised since 1870 and is regarded as a weed. Some species are considered serious threats to agriculture, and in some Australian states all species are considered noxious weeds that need to be reported and destroyed.
