Edison Rubber Quest Finds Madagascar Tree
Dr. Charles Swingle and a French colleague found Euphorbia intisy in Madagascar after a two nation expedition. The plant yields high grade rubber from cuts and survived the island’s rubber rush era while its desert adaptations include water jug roots. Seeds and cuttings now total about fifty plants in the U S Department of Agriculture and some are trialed outdoors near Miami Yuma and San Diego to test hardiness.
