Parasitic on clovers and other legumes; stems up to 60cm, yellowish and usually strongly tinged with red or purple; corolla (flower petals as a unit) 10-18mm, yellow, usually strongly tinged with purple; stigma usually purple (Stace,1997).
Parasite of a number of leguminous and non leguminous plants including red and white clover, burley tobacco, carrots, and several species of ornamental shrubs and herbs (Frost & Musselman, 1980).
Grasslands and landscapes dominated by forbs, mosses or lichens; Inland unvegetated or sparsely vegetated habitats
Flowers late May to mid September (Rumsey & Jury, 1981).
Pathway and vector description
Reportedly introduced to Ireland in clover seed (Reynolds, 2002), its spread here is likely to have been in seed contaminates similar to the pattern of spread in Britain (Rumsey & Jury, 1991).
Mechanism of impact
Parasite of other plants, mainly found in grasslands (Reynolds, 2002).
Europe, Temperate Asia
Established - Widespread & Fairly Common, found mainly in grassland (Reynolds, 2002). Pattern of distribution in the south east where botanical recording effort is high would suggest that this species is more common than records would indicate or is at the northern limit in Ireland.
Native to most of Europe, including Britain, but also into temperate Asia (Rumsey & Jury, 1991).
