Lathyrus/ˈlæθɪrəs/[3]is agenusofflowering plants in thelegumefamilyFabaceae,and contains approximately 160 species. Commonly known aspeavinesorvetchlings,[1]they arenativetotemperateareas, with a breakdown of 52 species in Europe, 30 species in North America, 78 in Asia, 24 in tropical East Africa, and 24 in temperate South America.[4]There areannualandperennialspecies which may be climbing or bushy. This genus has numerous sections, includingOrobus,which was once a separate genus.[5]The genus has numerous synonyms, includingPisum,the ancientLatinname for the pea.[6]

Uses

[edit]

Several species are grown for food, including thepea(Lathyrus oleraceus),Indian pea(L. sativus), and thered pea(L. cicera), and less commonlycyprus-vetch(L. ochrus) andSpanish vetchling(L. clymenum). Thetuberous pea(L. tuberosus) is grown as aroot vegetablefor its starchy edibletuber.Theseedsof someLathyrusspecies contain the toxicamino acidoxalyldiaminopropionic acidand if eaten in large quantities can causelathyrism,a serious disease.[7]

Many species are cultivated as garden plants. The genus includes the gardensweet pea(Lathyrus odoratus) and theperennialeverlasting pea(Lathyrus latifolius).Flowerson these cultivated species may be rose, red, maroon, pink, white, yellow, purple or blue, and some are bicolored. They are also grown for their fragrance. Cultivated species are susceptible tofungalinfections includingdownyandpowdery mildew.

Ecology

[edit]

Lathyrusspecies are used as food plants by thelarvaeof someLepidopteraspecies, including thegrey chi(Antitype chi) and thelatticed heath(Chiasmia clathrata), both recorded onmeadow vetchling(Lathyrus pratensis), andChionodes braunella.Lathyrusgrowth abundance and size both decrease in response to increased temperatures in montane meadows.[10]
