Morin is a yellow chemical compound that can be isolated from "Maclura pomifera" (Osage orange), "Maclura tinctoria" (old fustic) and from leaves of "Psidium guajava" (common guava).
 In a preclinical "in vitro" study, morin was found to be a weak inhibitor of fatty acid synthase with an IC of 2.33 μM.
 Morin was also found to inhibit amyloid formation by islet amyloid polypeptide (or amylin) and disaggregate amyloid fibers.
Moreae is a tribe within the plant family Moraceae.
 It includes 6–10 genera and 70–80 species, including "Morus", the genus that includes the mulberries, and "Maclura", the genus that includes the Osage orange.
Lathyrus sylvestris, the flat pea or narrow-leaved everlasting-pea, is a plant species of the genus "Lathyrus".
 It is native to parts of Africa, Europe, and Asia.
Lathyrus laevigatus is a flowering plant of the genus "Lathyrus" in the legume family Fabaceae.
 It is native to middle, eastern, and southeastern Europe.
Maclura is a genus of flowering plants in the mulberry family, Moraceae.
 It includes the inedible Osage orange, which is used as mosquito repellent and grown throughout the United States as a hedging plant.
Pomiferin is a prenylated isoflavone that can be found along with osajin in the fruits and female flowers of the osage orange tree ("Maclura pomifera").
Lathyrus nissolia or grass vetchling is a plant species of the genus "Lathyrus".
 It is native to the most areas in Europe, Maghreb, Levant and the Caucasus.
Sweet pea (Lathyrus odoratus) is a flowering plant in the genus "Lathyrus" in the family Fabaceae (legumes), native to Sicily, Cyprus, southern Italy and the Aegean Islands.
Lathyrus (commonly known as peavines or vetchlings) is a genus in the legume family Fabaceae and contains approximately 160 species.
 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.
 There are annual and perennial species which may be climbing or bushy.
 This genus has numerous sections, including "Orobus", which was once a separate genus.
Maclura pomifera, commonly known as the Osage orange, is a small deciduous tree or large shrub, typically growing to 8 to(-) tall.
 The distinctive fruit, from a multiple fruit family, is roughly spherical, bumpy, 3 to(-) in diameter, and turns a bright yellow-green in the fall.
 The fruits secrete a sticky white latex when cut or damaged.
 Despite the name "Osage orange", it is only very distantly related to the orange, and is instead a member of the mulberry family, Moraceae.

Question: Between Maclura and Lathyrus, which plant genus includes the inedible Osage orange?
Answer: Maclura
