Artichoke Artichoke The globe artichoke ("Cynara cardunculus" var. "scolymus") is a variety of a species of thistle cultivated as a food. The edible portion of the plant consists of the flower buds before the flowers come into bloom. The budding artichoke flower-head is a cluster of many budding small flowers (an inflorescence), together with many bracts, on an edible base. Once the buds bloom, the structure changes to a coarse, barely edible form. Another variety of the same species is the cardoon, a perennial plant native to the Mediterranean region. Both wild forms and cultivated varieties (cultivars) exist. This vegetable grows
Variety of finite semigroups an arbitrary set "P" of profinite identity "u" = "v", the set of semigroup satisfying "P" is the intersection of the set of semigroups satisfying all of those profinite identities. That is, it is an intersection of varieties of finite semigroup, and this a variety of finite semigroup. The definition of variety of finite semigroup is inspired by the notion of variety of universal algebra. We recall the definition of a variety in universal algebra. Such a variety is, equivalently: The main difference between the two notions of variety are now given. In this section "variety of (arbitrary) semigroup" means
