About Euphorbia regis-jubae J.Gay
Euphorbia regis-jubae J.Gay is a shrub that grows up to 2 meters (7 feet) tall. It has light brown stems, and narrow oblong leaves arranged in terminal rosettes, with leaf apexes that are either pointed or somewhat blunt. Its inflorescences grow on stalks, are shaped like umbels, and are most often simple with five to eight rays; more rarely, they are compound. The large greenish-yellow floral bracts are not joined at the base, and remain on the plant after fruit forms. The fruit capsules are light brown or red. Its seeds have a stalked elaiosome, also called a caruncle. This species is native to the eastern Canary Islands (Gran Canaria, Lanzarote, and Fuerteventura), western Morocco, and north-western Western Sahara. Its distribution differs from that of Euphorbia lamarckii, which it has often been confused with. E. lamarckii is found in the western Canary Islands: Tenerife, north-western La Gomera, La Palma, and El Hierro. In Spanish, Euphorbia regis-jubae is called tabaiba morisca.
