Petaladenium urceoliferum is a species of flowering plant in the family Fabaceae. It is a tree native to northern Brazil. It grows in tropical lowland Amazon rainforest in the basin of the Rio Negro, a northern tributary of the Amazon.[2] It is the only member of the genus Petaladenium.[3][4] The genus belongs to tribe Amburaneae in subfamily Faboideae.[5]
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.[6] Petaladenium urceoliferum is unique among legumes in having fimbriate–glandular wing petals.[7]
