			L. Cicera, Linn., and L. Ochrus, DC., are annual forage plants.—L. tuberosus, Linn., has been imported. It differs from all described above by having tubers. It is a native of the northern parts of the Old World, and bears red flowers which are generally fewer and smaller than those of L. sylvestris.}}

			Lathyrus (name used by Theophrastus for some leguminous plant). Leguminosae. Annual and perennial, climbing and upright herbs and shrubby plants with pinnate leaves, half-sagittate stipules and showy papilionaceous flowers.

			Stems flat or winged, in some species: leaves. equally pinnate, ending in a tendril or in a point; lfts. 2 or several; stipules leafy, large and prominent, half-sagittate : flowers. solitary or racemose, on long axillary peduncles; calyx oblique-campanulate, 5-parted, the upper teeth often shorter; corolla dark blue, violet, rose, white or yellow, or a union of these, the standard large, broadly obovate or roundish, notched, with a short claw, the wings falcate-obovate or oblong, the keel shorter than the wings, incurved, obtuse; stamens diadelphous (9 and 1) or monadelphous below; ovary 1-celled, the pod several-seeded; style curved, usually twisted, flattened, hairy along the inner side: pod flat or terete, 2-valved, dehiscent.—A genus according to the Index Kewensis, of more than 200 species, occurring in the northern hemisphere, Amer., Eu., Asia, and in Afruits and 8. Amer. Orobus niger and O. vernus are common garden names, but Bentham & Hooker, also Engler & Prantl, make Orobus a subgenus of Lathyrus, characterized in part by the lack of tendrils. See Orobus.

			The genus is best known by the sweet pea. Most other forms are perennial, although some of these are cultivated as annuals. All are free-growing plants, so independent in their ways that they require a place to grow by themselves, apart from other plants of like habit or size. Hence they are to be grown alone, on trellises or against walls, in rock-gardens, or allowed to form a wild tangle among strong shrubs. The chief value of the annuals is for cut-flowers, although their part in the garden is not to be ignored. As a temporary screen in summer for shutting out unsightly objects, they are valuable, or for quickly covering trellises or rough places otherwise unsightly.

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. This genus has numerous sections, including ''Orobus'', which was once a separate genus.<ref>{{cite book | author = Fred, Edwin Broun; Baldwin, Ira Lawrence; McCoy, Elizabeth | date = 1932 | title = Root Nodule Bacteria and Leguminous Plants | publisher = UW-Madison Libraries Parallel Press | location = | id = ISBN 1-893311-28-7 | pages =142}}</ref>

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.
