the list contains some omissions, mistakes and misunderstandings. Here are some additions, corrections and clarifications:
Hemp bears nuts. The seed is found within the nut.
A bud in the narrow definition is a certain non-sexual or sexual organ, for you know an unripe shoot or flower.
A flower is a staminate or a two-sexual organ.
Pistils and nut are enclosed by the bract. The bract is NOT a "small reduced leaflet in Cannabis that appears below a pair of calyxes".
Sinsemilla is mostly made up of parthenocarpic bracts. But the narrow definition of parthenocarpy is the development of seedless fruits, in the case of cannabis this was hollow nuts -- not nutless bracts.
The calyx is the "skin" of a bud. The calyx is NOT the bract. The staminate calyx' shelter the flower. In the case of hemp which is a dioecious species, one pistillate calyx is found below each bract.
As a comparison, pistillate hop (HUMULUS LUPULUS) grows big calyx'. A bunch of them form a cone-shaped fruit. I do not know if hop grows bracts at all. The translucent nut skins resemble the tiger-striped nut skins of hemp. Hop flowers look exactly like hemp flowers except for a rounder shape and slightly smaller size.
In monoecious species, say plants with two-sexual flowers, the pistillate parts are the innermost parts of the flower, while the staminate parts surround the pistillate parts.
A trichome is a tri-comet, a three-pike. It is not a hair, a thric. C, K and CH are interchangeable. T and TH are not. Practically, a trichome is a hard, sharp needle on a plant. It fights off predators. It is made of one cell and hardened by compounds containing silicon, calcium or carbon. The stinging nettle has trichomes filled with ant-acid. Trichomes of hemp cause the one-way rough feel of the leaves. They are NOT filled with resin and cannabiniods at all, unless you define it that way.
Resin glands are cells and inter-cell spaces which produce or accumulate resin.
Hemp has resin gland cells called latifers (from latis which means long), long cells within the plant tissue. It also has resin glands on the surface. Starting with one cell each they grow into clusters of 8 to 32 cells when they are finally raised on stalks. One such stalk is made of several epidermal cells and is soft, not hard like a trichome. The resin glands put resin into a ballon in front of the cells. When touched by anything, for instance by a predator, the ballon breaks and spills the resin fluid. When the ballon is left intact on the dying, drying plant, the resin hardens.
