Exempel på hur man kan använda RACHIS i en mening

• For example, once-divided leaf blades having leaflets arranged on both sides of a rachis are pinnately compound leaves.
• In botany, this leaf stalk is generally called a petiole, but in regard to fronds specifically it is called a stipe, and it supports a flattened blade (which may be called a lamina), and the continuation of the stipe into this portion is called the rachis.
• Lygodium are unusual in that the rachis, or midrib, of the frond is thin, flexible, and long, the frond unrolling with indeterminate growth and the rachis twining around supports, so that each frond forms a distinct vine.
• It takes its common name from its dark, reddish-brown, glossy stipe and rachis (leaf stalk and midrib), which support a once-divided, pinnate leaf.
• These properties suggest that the individual feathers consisted of a central quill (rachis) with thinner barbs branching off from it, similar to but more primitive in structure than modern bird feathers.
• A pollen cone consists of a slender rachis with numerous spirally arranged microsporophylls around it.
• In flowering plants, as well as the blade of the leaf, there may be a petiole and stipules; compound leaves may have a rachis supporting the leaflets.
• In the gonad of the invertebrate nematode Caenorhabditis elegans, a rachis is the central cell-free core or axis of the gonadal arm of both adult males and hermaphrodites where the germ cells have achieved pachytene and are attached to the walls of the gonadal tube.
• Wild barley has two rows of spikelets, hulled grains, and a brittle rachis; domestication produced, successively, non-brittle, naked (hulless), and then six-rowed forms.
• The lamina (leafy area of the fronds) are simple or pinnate, and the individual pinnae are articulate to the rachis.
• The stimulus is transmitted as an action potential from a stimulated leaflet to the leaflet's swollen base (pulvinus), and from there to the pulvini of the other leaflets, which run along the length of the leaf's rachis.
• Sori are typically bilaterally symmetrical, though leaf forms have been observed with pinnae fertile only on a single side of the rachis.
• They use the petiole and leaf rachis to make blowgun darts and sleeping mats, the petioles for torches, the pinnae for kindling and the stems for firewood.
• The rachis bears rachillae, which are smaller branches which themselves bear the flowers, while the peduncle is the main stalk connecting the rachis with the stem of the plant.
• Wild barleys have clusters of three spikelets, and the callus is the portion of the rachis to which they attach.
• Senna obtusifolia is usually self pollinated as many flowers being fertilized before opening, Senna obtusifolia has one (in Caribbean and North American forms) to two (in South American forms) extrafloral nectaries on the upper surface of the rachis that usually attract ants, but occasionally attracts wasps, flies and small bees.
• When a peduncle arises from the ground level, either from a compressed aerial stem or from a subterranean stem (rhizome, tuber, bulb, corm), with few or no bracts except the part near the rachis or receptacle, it is referred to as a scape.
• Inflorescences racemes, of 3--9 whorls, each 3--15-flowered, decumbent to arching, to 62 ´ 8--18 cm, often proliferating; peduncles terete, 35–56 cm; rachis triangular; bracts distinct, subulate, 10–21 mm, coarse, margins coarse; pedicels erect to ascending, 2.
• In botany, a scape is a peduncle arising from a subterranean or very compressed stem, with the lower internodes very long and hence few or no bracts except the part near the rachis or receptacle.
• Nonetheless, differences between other ant-acacias can be seen through elongated cylindrical inflorescences, somewhat small stipular spines, terete—cylindrical—spines that wrap around a cross section, 3-5 often dome-shaped petiolar glands, a lack of rachis glands, and leaflets with lateral veins.
