A pitaya /pÉ¨ËtaÉª.É/ or pitahaya /ËpÉªtÉËhaÉª.É/ is the fruit of several cactus species. Pitaya  usually refers to fruit of the genus Stenocereus, while  pitahaya  or  dragon fruit  always refers to fruit of the genus Hylocereus. Hylocereus undatus (Pitaya blanca or white-fleshed pitaya) has red-skinned fruit with white flesh. 2  This is the most commonly seen dragon fruit. 3  Hylocereus costaricensis (Pitaya roja or red-fleshed pitaya, also known as Hylocereus polyrhizus) has red-skinned fruit with red flesh.
Pith, or medulla, is a tissue in the stems of vascular plants. Pith is composed of soft, spongy parenchyma cells, which store and transport nutrients throughout the plant. In eudicots, pith is located in the center of the stem. In monocots, it extends also into flowering stems and roots. The pith is encircled by a ring of xylem; the xylem, in turn, is encircled by a ring of phloem.
