#prick

• Prickly moses — A species of small thorny shrub endemic to southwestern Western Australia, remarkable for its ecological value and delicate beauty. The plant features true, finely divided, deep green bipinnate leaves, protected by sharp stipular spines located at the stem nodes. Popularly known as the 'prickly moses', this species is famous not only for its brilliant golden-yellow globular inflorescences, but also for its unique capacity to fix nitrogen in the soil and to display a natural resistance against the destructive attacks of the dieback fungus Phytophthora cinnamomi.
• Acanthesthesia — A form of paresthesia or subjective disturbance of tactile and painful sensitivity, characterized by a false, spontaneous, and unpleasant sensation of pinpricks or thorn-like pricks on the skin, occurring in the absence of any external mechanical stimulus. This neurological symptom is typically associated with damage to peripheral nerve fibers, being encountered in neuropathies, radiculopathies, or lesions of the sensory pathways in the spinal cord.
• Aralia spinosa — The scientific binomial name for Hercules' club or devil's walking stick, a large deciduous shrub or small tree in the Araliaceae family, native to the eastern United States. It is recognized in botany by stems and branches armed with very sharp prickles, exceptionally large bipinnate compound leaves (among the largest in North American flora), and massive terminal paniculate inflorescences of white flowers followed by dark purple berries favored by wildlife.
• Argemone — A taxonomic genus of annual or perennial herbaceous plants in the family Papaveraceae, native to the semi-arid regions of the Americas, characterized by spiny leaves resembling thistles and large, decorative flowers with white or yellow petals; species of this genus secrete a bright yellow, highly toxic latex rich in isoquinoline alkaloids with complex medicinal and industrial properties.
• Argemone alba — A species of annual or biennial herbaceous plant in the Papaveraceae family, native to the central and southern regions of North America, commonly known as the white prickly poppy. The plant is structurally characterized by erect, branched stems heavily covered with rigid prickles, lobed leaves with prominent whitish veins, and large, solitary flowers whose immaculate white petals surround a dense center of numerous bright yellow anthers, secreting a toxic yellowish latex.
• Argemone grandiflora — A species of annual or perennial herbaceous plant in the genus Argemone, family Papaveraceae, native to Mexico and neighboring regions, commonly known as the large-flowered prickly poppy. The plant is structurally distinguished by its bluish-grey (glaucous) foliage, robust stems that are less prickly than those of other species in the genus, and spectacular inflescences with large flowers whose delicate, crinkled, immaculate white petals can reach diameters of up to 10-12 centimeters.
• Mexican prickly poppy — A species of pricklepoppy in the family Papaveraceae, native to Mexico and currently widespread across tropical and subtropical regions of the world, commonly known as Mexican prickly poppy. In a structural-botanical sense, this annual plant is adapted to degraded and dry soils, featuring rigid leaves with whitish veins and deeply jagged margins ending in sharp spines, large bright-yellow flowers, and prickly capsules filled with small black seeds; its yellow latex contains toxic alkaloids historically used in traditional medicine and pharmacological research.
• Crested pricklepoppy — A species of pricklepoppy in the family Papaveraceae, native to the mountainous and arid regions of Mexico and the southwestern United States, commonly known as crested pricklepoppy or broad-horned prickly poppy. In a structural-botanical sense, this erect, perennial or annual plant features bluish-silver foliage densely covered with spiny hairs, large, showy flowers with paper-white petals and yellow anthers, and fruiting capsules ending in prominent, flattened horn-like appendages.
• Prickly weed — An extremely rare popular or regional name assigned to certain species of herbaceous plants or weeds whose fruits, stems, or leaves are equipped with coarse hairs, spines, or clinging structures resembling a hedgehog's coat (such as certain thistles or Medicago species). In specific regions, the term can represent a phonetic variant or a structural micro-diminutive derived from the root 'arici', used empirically in ethnobotany.
• Thistles — A popular or regional name used in certain rural or dialectal areas to designate various herbaceous plants whose fruits, inflorescences, or stems are covered with thorns, prickles, or rigid clinging hairs (such as burdocks, thistles, or the Xanthium genus); figuratively, the term can describe rudimentary jagged objects or coarse brushes used in traditional households.
• Prick — The result of bristling or roughening; a shaggy, rough portion or an area full of thistles and spines on a textile, plant, or skin surface. In regional dialects, the term can be used to describe a small puncture, sting, or scratch caused by plant thorns or animal spines, leaving the skin structurally inflamed and rough.
• Prickly — Full of thorns, spikes, or prominent roughness; presenting a rigid and bristled structure similar to the protective coat of a hedgehog. In an extended or figurative sense, the term can describe a grumpy, sharp, or defensive human behavior, characterized by a tendency to repel social interactions with cutting remarks.
