Each female marijuana flower has two stigmas that protrude from a single ovule; they are “fuzzy” (hirsute), about ¼ to ½ inch long, usually white, but sometimes yellowish, or pink to red and, occasionally, lavender to purple.
Male plants also form all of these trichomes, and until flowering, concentrations of cannabinoids are similar in male and female plants. With the onset of flowering, female plants produce much more cannabinoids than males, primarily because of the concentration and size of capitate-stalked resin glands on female flowers and associated small leaves (bud leaves) that intersperse flower clusters.
A well-pollinated typical bud develops from 50 to 150 seeds, a cola easily holds many hundreds, and even a small, but thoroughly pollinated female can bear thousands of seeds.

By definition, a perianth consists of a corolla and a calyx. In more familiar showy flowers, the corolla is the brightly colored petals we generally appreciate when looking at flowers, and the calyx is the smaller green cup (sepals) holding the petals at the flower’s base.
Capitate-stalked glands are the largest, are the main source of cannabinoid accumulation, and are plainly visible on female flowers. While almost all cells in a cannabis plant are capable of producing minute amounts of cannabinoids, capitate-stalked glands contain at least 50% of the total cannabinoids in a plant. Since female flowers (buds) are the main smokeable product, and buds are the main locus of capitate-stalked glands, these glands are our main source of cannabinoids and terpenes.
Cannabis female flowers do have calyx cells, but not a defined calyx. The female cannabis calyx cells are one part of the perianth, a nearly transparent, delicate tissue that partially encloses the ovule (prospective seed).
Cannabis flowers are not brightly colored, large, or enticingly fragrant (at least to most non-humans); marijuana plants are wind-pollinated with no need to attract insects or animals to carry the males’ pollen, hence these plant parts never evolved into significant, attractive, or showy parts.
Cannabis has six kinds of trichomes: three are non-glandular and three are glandular and resin-bearing. Cystolith hairs are the most visible of the non-glandular as these needle-like “hairs” prominently cover all of the above-ground plant parts: stems, branches, leaves, petioles and flowers.
The Cannabis Female Flower From O’Shaughnessy’s Winter 2018/19 By Mel Frank In the cannabis industry, the general terms—bud, cola, nug— are easy enough and universally accepted,

Definition – What does Calyx mean?
Flowers have a particular physical design that helps to support and protect them, while ensuring access to pollinators. The calyx is the base of the flower, the part that forms first.
In cannabis cultivation, the calyx, or calyxes (plural), is important for another reason – it contains high concentrations of resin.
The calyx is part of the bud on a cannabis plant, and is usually part of the larger cola, as well.
MaximumYield explains Calyx
All flowering plants must ensure that their flowers are protected, stable, and able to grow large enough to attract their preferred pollinators. The calyx is the part of the flower that forms first, and eventually becomes the base that supports the rest of the flower.
Within the cannabis calyx, you will find all of the important reproductive organs, including the pistil and stigmas. You’ll also find resin glands, which are responsible for producing cannabinoids, including THC.
In most instances, the bud that is harvested from the cannabis plant is primarily composed of the calyx, although the pistils are also included in most cases. This is because these two flower components contain the highest concentrations of THC. They are very important in nug-run concentrate production, but are rarely used in trim-run concentrates, which are made up of general trimmings and other secondary plant matter.
In a mature female plant, the calyx will grow, and eventually open to expose the pistils, which look like long, white hairs. In a male, this does not occur. Instead, the buds droop down and form pollen. Over time, the pistils begin to change color, moving from white to white/yellow, and then reddish yellow, before eventually turning brown and dying. The calyx should be harvested prior to the final stage (browning), usually after six to seven weeks.
