The term used to describe a cluster of flowers along an elongated stem is "raceme." A raceme is a specific type of inflorescence where flowers are attached by short stalks along the central stem, allowing for a linear arrangement. This structure allows the flowers to bloom along the length of the stem, often starting from the bottom and moving towards the top, giving it a distinctive appearance.

Understanding the morphology of floral structures like racemes is essential, especially in the context of plant identification and horticulture, as it helps in recognizing various plant species and their growth patterns. Other options, while related to flower arrangements, refer to different forms; for example, a spike is similar but features flowers that lack individual stalks, directly attached to the stem, while inflorescence is a broader term that encompasses all types of flower arrangements. Cluster may be a general term but does not specifically define the elongated stem arrangement.
