Petaladenium

Petaladenium urceoliferum is a species of flowering plant in the legume family, Fabaceae. It belongs to the subfamily Faboideae. It is the only member of the genus Petaladenium.[2][3][4] It produces three chemical compounds in its leaves that are not found in other members of the Amburaneae: (2S,4S,5R)-5-hydroxy-4-methoxypipecolic acid, (2S,4R,5S)-5-hydroxy-4-methoxypipecolic acid, and (2S,4R,5R)-4-hydroxy-5-methoxypipecolic acid.[5] Petaladenium urceoliferum is unique among legumes in having fimbriate–glandular wing petals.[6]
