The [[genus]] '''''Lathyrus''''' consists of the '''sweet peas''' and '''vetchlings''', [[flowering plant]]s in the [[legume]] family [[Fabaceae]]. There are approximately 160 species of ''Lathyrus''; they are native to [[temperate]] areas, 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.<ref>{{cite journal |author=Asmussen, Conny B; Liston, Aaron| title= Chloroplast DNA Characters, Phylogeny, and Classification of Lathyrus (Fabaceae)| journal= American Journal of Botany| year=March 1998 | volume=85| issue=3| pages= 387| url=}}</ref> There are [[Annual plant|annual]] and [[Perennial plant|perennial]] species which may be climbing or bushy.

The genus includes the garden [[sweet pea]] (''Lathyrus odoratus'') and the [[Perennial plant|perennial]] [[everlasting pea]] (''Lathyrus latifolius''). [[Flower]]s on these cultivated species may be rose, red, maroon, pink, white, yellow, purple or blue and some are bicolored; they are also fragrant, which makes them a very popular garden plant. Cultivated species are susceptible to [[fungal]] infections including downy and powdery [[mildew]]. ''Lathyrus'' species are used as food plants by the [[larva]]e of some [[Lepidoptera]] species including [[Grey Chi]], [[Latticed Heath]] (both recorded on [[Meadow Vetchling]]) and ''[[Chionodes|Chionodes braunella]]''.
Other species are grown for food, including ''[[Lathyrus sativus|L. sativus]]'' and ''L. cicera'', and less commonly ''L. ochrus'' and ''L. clymenum''. ''[[Lathyrus tuberosus|L. tuberosus]]'' is grown as a [[root vegetable]] for its starchy edible [[tuber]].
The [[seed]]s of some ''Lathyrus'' species contain a toxic [[amino acid]] and if eaten in large quantities can cause [[lathyrism]], a serious disease.
