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 ...
In reference to an inflorescence (a shoot specialised for bearing flowers, and bearing no leaves other than bracts), an indeterminate type (such as a raceme) is one in which the first flowers to develop and open are from the buds at the base, followed progressively by buds nearer to the growing tip. The growth of the shoot is not impeded by the ...

The plant lives about forty years, blooming about every fourth year. The inflorescence springs up from a corm weighing up to 257 lbs 6 oz. (117 kilograms). A corm grown by Dr. Louis Ricciardello of Gilford, New Hampshire is claimed to have weighed 305 pounds (138 kilograms) and produced an inflorescence 10 ft 2.25 in (3.1052 meters) in height.
The leaves range in colour from red to green, but always have distinctive "H-shaped" spots. The flowers are similarly variable in colour, ranging from bright red to yellow, but are always bunched in a distinctively flat-topped raceme. The inflorescence is borne on the top of a tall, multi-branched stalk and the seeds are reputedly poisonous.
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. [4]
The inflorescence is a raceme at the end of the stalk. Individual flowers are borne on 1–3.5 millimetres (0.039–0.138 in) long pedicels. The banner petal is oblong to circular, typically blue with the center white, 5–7 millimetres (0.20–0.28 in) long.
