OROBANCHE. Broomrapes. [Orobanchaceae]

Fourteen species of Orobanche are recorded in Britain. These include the native Thyme Broomrape (O. alba), Oxtongue Broomrape (O. artemisiae-campestris), Bedstraw Broomrape (O. caryophyllacea), Knapweed Broomrape (O. elatior), Ivy Broomrape (O. hederae), Common Broomrape (O. minor), Yarrow Broomrape (O. purpurea), Greater Broomrape (O. rapum-genistae) and Thistle Broomrape (O reticulata). The BSBI provide a downloadable plant crib for Orobanche.

Oxtongue Broomrape (O. artemisiae-campestris), Bedstraw Broomrape (O. caryophyllacea) and Thistle Broomrape (O reticulata) are protected under Schedule 8 of the Wildlife and Countryside Act, 1981.

Ivy Broomrape (O. hederae) is protected in Northern Ireland under Schedule 8 of the Wildlife (Northern Ireland) Order, 1985.

No miners are recorded on Orobanche.

One dipterous miner, Chyliza extenuata, is said to live in the swollen underground stem of Orobanche rapum-genistae Thuill., a perennial root parasite of leguminous shrubs, especially Ulex europaeus and Cytisus scoparius, but also known to occur occasionally on Genista tinctoria in Britain (Collin, 1944. Ent. mon. Mag. 80: 214-224.). It is not known whether it mines or not.

The agromyzid Phytomyza orobanchia is recorded feeding in both the seed-heads and stems of Orobanche spp. elsewhere.
