Orobanche minor
lesser broomrape
Parasitic plant which sends up a flower spike from fleshy tubers. It does not photosynthesise so has no leaves or green bits. The flowers are usually brown or purple.
The only species of broomrape in NZ. Some orchids have a similar flower, but they have (green) leaves as well.
Naturalised in both islands but rare.
Possibly glycosides, resins and tannins.
Grazing animals. No cases reported in NZ, and very few from overseas, probably because animals do not normally eat it. Feeding trials have shown toxic effects in goats and dogs.
Goats reduced appetite and rumination, depression, prostration and thirst; followed by death.
Dogs diuresis.
