2023年2月2日 · iv) Spike: Sessile flowers borne acropetally over an elongated peduncle. Examples – Malabar nut, chaff-flower, bottle brush, Amaranthus, and Verbena. v) Spikelet: It is a compact dry spike with only one or a few sessile flowers born on a specialized axis called the rachilla. It remains surrounded at the base by two scaled bracts called glumes.

Many verticillasters with reduced bracts can form a spicate (spike-like) inflorescence that is commonly called a spike.
Spike | inflorescence | Britannica
In inflorescence: Indeterminate inflorescence. A spike is a raceme, but the flowers develop directly from the stem and are not borne on pedicels, as in barley (Hordeum). A spike is a raceme except that the flowers are attached directly to the axis at the axil of each leaf rather than to a pedicel.
6 Major Types of Inflorescence (With Diagrams) | Botany
Spikeletes are arranged in a spike inflorescence which is composed of several to many spikelets which are combined in various manners on a main axis called the rachis. Some are in compound spikes (i.e., in wheat—Triticum aestivum), others are in racemes (e.g., in Festuca), while some are in panicles (e.g., in Avena).

The inflorescence is a compact unisexual, often hanging, spike which matures and falls down as a single unit, e.g., Mulberry (Morns, vern. Shahtoot), Poplar (Populus), Willow (Salix), Red Hot Cattail (Acalypha hispidd), Betula, Quercus.
