Biology:Ochrea
From HandWiki
An ochrea (Latin ocrea, greave or protective legging), also spelled ocrea, is a plant structure formed of stipules fused into a sheath surrounding the stem.[1][2] It is typically found in the buckwheat family Polygonaceae and in some members of the orchid family Orchidaceae.[3][4] In the palm family Arecaceae, it is an extension of the leaf sheath beyond the petiole insertion.[5]
