A study on the physiology of root parasitism in sandal (Santalum album L.) was conducted by comparing a six-year-old sandal grown alone and along with a host (Casuarina equisetifolia). Although maximum haustorial connections were observed when grown along with the host, sandal formed haustorial connections with plants including grass up to a distance of 3 m. Anatomical studies on haustoria indicated a vascular connectivity between the host and sandal.
