Piperales is an order of flowering plants. It necessarily includes the family Piperaceae but other taxa have been included or disincluded variously over time. Well-known plants which may be included in this order include black pepper, kava, the many Peperomias, pepper elder, lizard's tail, birthwort, and wild ginger. The two perianthless families Piperaceae and Saururaceae are mainly herbaceous plants possessing highly reduced flowers.
The Aristolochiaceae are a family, the birthwort family, of flowering plants with seven genera and about 400 known species belonging to the order Piperales. The type genus is Aristolochia L.
Dutchman's pipe is a common name for some unrelated flowering plants, which have flowers, inflorescences or stems resembling a pipe:
Cistus creticus is a species of shrubby plant in the family Cistaceae. Though it usually has pink flowers, of 4.5–5 cm diameter, this species is very variable. It is widely known as a decorative plant. It is frequently called "Cistus incanus".
Calymmanthium is a monotypic genus of primitive tree-like cacti from northern Peru. The only species is Calymmanthium substerile. It belongs to the tribe Lymanbensonieae. Calymmanthium is absolutely unique among flowering plants in the mode of its floral development. The young flower is completely encased within the plant's stem until it is fully developed, at which time a crack develops in the stem, allowing pollinators access.
Aristolochia californica, the California pipevine, California Dutchman's-pipe, or California snakeroot is a perennial woody vine of western North America.
Hydnoroideae is a subfamily of parasitic flowering plants in the order Piperales. Traditionally, and as recently as the APG III system it given family rank under the name Hydnoraceae. It is now submerged in the Aristolochiaceae. It contains two genera, Hydnora and Prosopanche:
Nepenthes boschiana, or Bosch's pitcher-plant, is a tropical pitcher plant endemic to Borneo. It is most closely allied to N. faizaliana. Nepenthes borneensis is considered a synonym of this species. Nepenthes boschiana has no known natural hybrids. No valid forms or varieties have been described. Nepenthes boschiana belongs to the loosely defined "N. maxima complex", which also includes, among other species, N. chaniana, N. epiphytica, N. eymae, N. faizaliana, N. fusca, N. klossii, N. maxima, N. platychila, N. stenophylla, and N. vogelii.
Nepenthes diatas is a tropical pitcher plant endemic to Sumatra, where it grows at an altitude of 2,000–2,900 metres (6,600–9,500 ft) above sea level.
Aristolochia littoralis, the calico flower or elegant Dutchman's pipe, is a species of evergreen vine belonging to the family Aristolochiaceae.
Cistus monspeliensis is a species of rockrose known by the common name Montpellier cistus or narrow-leaved cistus. It is native to southern Europe and northern Africa, in the Mediterranean forests, woodlands, and scrub ecosystems of matorral—maquis shrublands.
Aristolochia serpentaria is a species of perennial flowering plant in the Aristolochiaceae (birthwort) family. The species is commonly known as Virginia snakeroot and is native to eastern North America, from Connecticut to southern Michigan and south to Texas and Florida.
Aristolochia maxima is a plant species native to Central and South America, naturalized in southern Florida. Common names include Florida Dutchman's-pipe (US), canastilla (Guatemala), guaco, and tecolotillo (Mexico). In Florida, it grows in hammocks in the Everglades at elevations below 50 m.
Aristolochia macrophylla, Dutchman's pipe or pipevine, is a perennial vine native to the eastern United States. A. macrophylla belongs to the plant family Aristolochiaceae and is found primarily along the Cumberland Mountains and Blue Ridge Mountains in the eastern portion of the United States, as well as Ontario, Canada. This species of plant has received considerable attention in the past few decades for the discovery of a potent compound called aristolochic acid, which has been the focus of debate due its harmful side effects.
Cistus palmensis is a shrubby species of flowering plant in the family Cistaceae.
Cistus populifolius is a shrubby species of flowering plant in the family Cistaceae.
Cistus pouzolzii is a shrubby species of flowering plant in the family Cistaceae.
Cistus sintenisii is a shrubby species of flowering plant in the family Cistaceae. It was named in honor of Paul Sintenis.
Aristolochia reticulata, the Red River snakeroot, Texas Dutchman's pipe, or Texas pipevine, is a species of perennial herb in the family Aristolochiaceae, and endemic to Arkansas, Louisiana, Oklahoma, and Texas. Its habit is erect to sprawling, up to 0.4 meters in height. It flowers in summer and late spring, and summer and grows in moist, sandy soils.
Aristolochia gorgona is a recently discovered (2002) flowering plant in the Dutchman's pipe family (Aristolochiaceae) found in the Atlantic-facing rainforests of Costa Rica and Panama. It differs from Aristolochia grandiflora in lacking the sometimes very long "tail" that hangs down from the trumpet of A. grandiflora, in being darker and in being covered with inch-long (2.5 cm) tendril-like enations which have suggested a comparison to Medusa and her sisters. With a trumpet up to 12.5 inches (32 cm) top to bottom, twelve inches (30 cm) wide and about 15 inches (38 cm) deep A. gorgona is one of the largest flowers in the New World. Its discoverer, Blanco thought its very late discovery might be due to its similarity to A. grandiflora. This resemblance must be that of the foliage, for as we have seen the flowers are very different.
