Euphorbia Lamarckii
''Euphorbia lamarckii'' is a species of flowering plant in the family Euphorbiaceae, native to the western Canary Islands (Tenerife, north-western La Gomera, La Palma and El Hierro). It resembles ''Euphorbia regis-jubae'', with which it has been confused. Both have been called ''Euphorbia obtusifolia''. Description ''Euphorbia lamarckii'' resembles ''Euphorbia regis-jubae''; their distributions do not overlap. It is a shrub up to tall, with light brown stems, undivided leaves and small yellowish-green floral bracts. The inflorescence is usually a compound umbel. The elaiosome (caruncle) attached to a seed is sessile or has only a very short stalk. It differs from other Canary Island species of ''Euphorbia'' in the shape of the compound, umbel-like inflorescences, that are yellow-greenish in colour, and by the floral bracts falling off before the fruit ripens.
