''Lathyrus linifolius'' is a species of pea, commonly called bitter vetch or heath pea. The name bitter vetch is also sometimes used for ''Vicia ervilia'' and also for ''Vicia orobus''. The tubers of ''Lathyrus linifolius'' were formerly used as an appetite suppressant in medieval Scotland, and this use has brought the plant to recent medical attention. Attempts are being made to cultivate the plant on a commercial scale. ==Description== ''Lathyrus linifolius'' is a perennial plant with dark-coloured tubers attached to the roots. The stem grows to and is erect, winged and nearly hairless. The leaves are alternate with short winged stalks and large stipules. The leaf blades are pinnate with two to four pairs of narrow lanceolate leaflets with blunt tips, entire margins and no tendrils. The inflorescence has a long stem and two to six red flowers, each long, turning bluer as they age. These have five sepals and five petals and are irregular. The uppermost petal is known as the "standard", the lateral two as the "wings" and the lowest two are joined to form the "keel". There are ten stamens and a single carpel. The fruit is a long reddish-brown pod containing up to ten seeds. This plant flowers in May and June.〔(【引用サイトリンク】title=Bitter vetch: ''Lathyrus linifolius'' )〕
