Consequently, the supremum is also referred to as the least upper bound (or LUB). [1] The infimum is, in a precise sense, dual to the concept of a supremum. Infima and suprema of real numbers are common special cases that are important in analysis, and especially in Lebesgue integration.
Various folk cultures and traditions assign symbolic meanings to plants. Although these are no longer commonly understood by populations that are increasingly divorced from their rural traditions, some meanings survive. In addition, these meanings are alluded to in older pictures, songs and writings.

The supremum/superior/outer limit is a set that joins these accumulation sets together. That is, it is the union of all of the accumulation sets. When ordering by set inclusion, the supremum limit is the least upper bound on the set of accumulation points because it contains each of them. Hence, it is the supremum of the limit points.
The supremum of B is then equal to the infimum of X: since each element of X is an upper bound of B, sup B is smaller than all elements of X, i.e. sup B is in B. It is the greatest element of B and hence the infimum of X. In a dual way, the existence of all infima implies the existence of all suprema.
Infima and suprema do not necessarily exist. Existence of an infimum of a subset S of P can fail if S has no lower bound at all, or if the set of lower bounds does not contain a maximal element. However, if an infimum or supremum does exist, it is unique. Is the below not a counterexample. (if a rather odd one)
Illustration from Floral Poetry and the Language of Flowers (1877). According to Jayne Alcock, grounds and gardens supervisor at the Walled Gardens of Cannington, the renewed Victorian era interest in the language of flowers finds its roots in Ottoman Turkey, specifically the court in Constantinople [1] and an obsession it held with tulips during the first half of the 18th century.
The leaves are opposite, 5–12 cm long, pinnate with 5–11 leaflets. The flowers are produced in open cymes, the individual flowers are white having corolla with a basal tube 13–25 mm long and five lobes 13–22 mm long.
