Branched: Aerial stems are described as being branched or unbranched. Bud: An embryonic shoot with immature stem tip. Bulb: A short vertical underground stem with fleshy storage leaves attached, e.g. onion, daffodil, and tulip. Bulbs often function in reproduction by splitting to form new bulbs or producing small new bulbs termed bulblets.
The latter term is an affix found in other modern words such as cladodont (prehistoric sharks with branched teeth), cladode (flattened leaf-like branches), or cladogram (a branched diagram showing relations among organisms).
The stem of a plant, especially a woody one; also used to mean a rootstock, or particularly a basal stem structure or storage organ from which new growth arises. Compare lignotuber. caudiciform Stem-like or caudex-like; sometimes used to mean "pachycaul", meaning "thick-stemmed". caudicle diminutive of caudex.
Herbaceous plants (also called herbs or forbs): a plant whose structures above the surface of the soil, vegetative or reproductive, die back at the end of the annual growing season, and never become woody. While these structures are annual in nature, the plant itself may be annual, biannual, or perennial. Herbaceous plants that survive for more ...
Prickles on a blackberry branch. In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called spinose teeth or spinose apical processes), are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically defending plants against herbivory.
The reconstruction shows horizontal and upright stem-like structures; no leaves or roots are present. The upright stems or axes branch dichotomously and have pairs of spore-forming organs attached to them. Cross-sections of the upright axes showed that vascular tissue was present. He later described other specimens.
The woody central stem is branched or unbranched depending on the variety and may be green, red or purple. The flowering panicles arise from the top of the plant or from leaf axils along the stem. Each panicle has a central axis from which a secondary axis emerges either with flowers (amaranthiform) or bearing a tertiary axis carrying the ...
The upright stems contains small green filaments, and the branched horizontal stems is where the tree-like structure (2-10cm) grows out from. [2] Their capsules are upright and oblong-cylindric, ranging from 1.5-4 mm, they are quite rare to encounter since male plants are more rare than female ones.
