Exempel på hur man kan använda ACHENES i en mening

• The fleshy and edible part of the "fruit" is a receptacle, and the parts that are sometimes mistakenly called "seeds" are achenes and therefore the true botanical fruits.
• The fruits are ovoid to obovoid shaped achenes that are collected together in a tight cluster, ending variously lengthened stalks; though many species have sessile clusters terminating the stems.
• Seeds are achenes and are borne in a globe like that of a dandelion but larger, and are dispersed by the wind.
• Some achenes have accessory hair-like structures that cause them to tumble in the wind in a manner similar to a tumbleweed.
• These differ from other thistle genera (Carduus, Silybum and Onopordum) in having a seed with a pappus of feathered hairs on their achenes.
• The silky-hairy, fusiform achenes form a crown with a double pappus in two series, the inner one with long, barbellate bristles, the outer one with short bristles or minute scales.
• Once pollinated by a fig wasp, the individual florets inside the syconium develop into achenes or drupes, in which the seeds are enclosed by a layer of endocarp.
• The classic examples of these dispersal mechanisms, in the temperate northern hemisphere, include dandelions, which have a feathery pappus attached to their fruits (achenes) and can be dispersed long distances, and maples, which have winged fruits (samaras) that flutter to the ground.
• The achenes bear a beak-like tubercule (hence the name “beak-rush”, although the plants are sedges, not rushes) and are sometimes subtended by bristles.
• False mayweed achenes usually have less space between the ribs, the resin glands cannot be seen from the top of the achene, and the resin glands are often brown and oval rather than round and reddish compared to scentless chamomile.
• The minute, sharply-pointed, bristly pappus hairs easily detach from the top of the achenes and are carried by the slightest breeze – attaching to skin, mucous membranes, and eyes where they can cause severe dermal irritation, possible respiratory manifestations, and ophthalmia.
• At other seasons in California, it predominantly eats chamise achenes and also berries of mistletoe (Phoradendron) and California Buckthorn.
• The fruits (seeds) of Symphyotrichum lateriflorum are not true achenes but are cypselae, resembling an achene and surrounded by a calyx sheath.
• Calendula arvensis produce three types of achenes (fruits of the sunflower family), they are rostrate, cymbiform and annular.
• Members of Steviopsis are perennial herbs that have heads composed entirely of disk flowers, a pappus of capillary bristles, narrow corollas with spreading lobes, and glands on the cypselae (achenes).
• The fruit is a club-shaped achene just under a centimeter long; achenes arising from the disc florets have pappi of scales.
• They are subshrubs, shrubs, or small trees with a base chromosome number of 9, whose fruits are either an achene or an aggregate of achenes.
• The genus was originally described to include one (later two) species of subtribe Helianthinae that were characterized by having pales that tightly enclosed the cypselae (achenes) (see Feddema, 1971).
• Florestina is distinguished from Palafoxia by its 3-5 lobed leaves, whitish corollas, and cypselae (achenes) which are only sparsely pubescent and with the trichomes curled (rather than straight).
• Each seed head (or infructescence) on female plants consists of multiple achenes (an aeterio) with each seed bearing a plumose awn 2–4.
