The inflorescence of a Phalaenopsis orchid is a typical raceme. A raceme (/ r eɪ ˈ s iː m, r ə-/) or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in ...
A raceme is an unbranched, indeterminate inflorescence with pedicellate (having short floral stalks) flowers along the axis. A spike is a type of raceme with flowers that do not have a pedicel. A racemose corymb is an unbranched, indeterminate inflorescence that is flat-topped or convex due to their outer pedicels which are progressively longer ...

Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials . This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain.
The inflorescence bears 6–20 flat star shaped flowers on ascending stems , 3–3.5 cm (1 + 1 ⁄ 4 – 1 + 1 ⁄ 2 in), associated with membranaceous leaflets , 2.5–3 cm (1– 1 + 1 ⁄ 4 in), in an open branching umbrella shaped terminal cluster, described as a corymbose raceme. [3]
The species epithet 'racemosa' refers to the elongated raceme inflorescence of the species, which differentiates it from other species in the genus. [2] Raceme comes from the latin 'racemosus' meaning full of clusters or clustering.
