Sha (S. "Ningalen", Q. "Nelcica") was a very hard to find member of the water lily family native to the high altitude boglands of Eriador.It had the characteristic flat, green, upper part that was visible above the surface of the water. Below the water hang dozens of roots. A single, pink blossom in the center of the floating plant appeared in spring.
When dried, powdered and imbibed with any beverage, the sha flower confered the ability to see in all but total darkness (up to 300') for 10-50 seconds. 11 -20 hours after consumption, the sha imbiber was stricken with severe diarrhea for 1-5 days, reducing him (at best) to an ineffective state until he recovered.
