Question: Which genus of plant life is more palm like, Pandanus or Eriogonum? 

full_context: Document 1: Borassus: Borassus (Palmyra palm) is a genus of five species of fan palms, native to tropical regions of Africa, Asia and New Guinea. These massive palms can grow up to 30 m high and have robust trunks with distinct leaf scars; in some species the trunk develops a distinct swelling just below the crown, though for unknown reasons. The leaves are fan-shaped, 2–3 m long and with spines along the petiole margins (no spines in "B. heineanus"). The leaf sheath has a distinct cleft at its base, through which the inflorescences appear; old leaf sheaths are retained on the trunk, but fall away with time. All "Borassus" palms are dioecious, with male and female flowers on separate plants; male flowers are less than 1 cm long and in semi-circular clusters, sandwiched between leathery bracts in pendulous catkins; female flowers are 3–5 cm wide, globe-shaped and solitary, sitting directly on the surface of the inflorescence axis. The fruits are 15–25 cm wide, roughly spherical and each contain 1-3 large seeds. Depending on species, fruit color varies from black to brown, yellow or orange; the fibrous pulp is aromatic and sweet to taste. Each seed is enclosed in a woody endocarp, which protects it when the fruit is consumed by elephants, monkeys and other frugivores. At germination, the young seedling extends downwards into the soil and only a few leaves are visible above ground; this provides some protection against frequent fires in its savanna habitat; after an indeterminate number of years (the establishment phase), the seedling forms a stem and quickly grows above the savanna vegetation, where it is then less vulnerable to fire.
Document 2: Polygonum sawatchense: Polygonum sawatchense is a North American species of plants in the buckwheat family. It in the western United States and western Canada, from the Pacific Coast to the western Great Plains, so from British Columbia south to California and east as far as New Mexico, Colorado, Saskatchewan, and the Dakotas.
Document 3: Polygonum californicum: Polygonum californicum is a species of flowering plant in the buckwheat family known by the common name California knotweed. It is native to the west coast of the United States from Washington, Oregon, and northern and central California in the Coast Ranges and Sierra Nevada foothills as far south as Napa and Tulare Counties. It can be found in many types of open habitats.
Document 4: Eriogonum gilmanii: Eriogonum gilmanii is a species of wild buckwheat known by the common name Gilman's buckwheat. This plant is endemic to Inyo County, California, where it is known only from the desert mountain slopes of the Cottonwood, Last Chance, and Panamint Ranges. This is a flat mat-forming, woody perennial herb which grows in patches under 20 centimeters wide on rocky soils. Its tiny fleshy leaves, each under half a centimeter wide, are covered in a dense hairy white wool. The plant blooms in showy erect heads of small, inflated flowers, each a few millimeters wide and yellowish or orange with red stripes.
Document 5: Pandanales: Pandanales (pandans or screw-pines) is the botanical name for an order of flowering plants placed in the monocot clade in the Angiosperm Phylogeny Group and Angiosperm Phylogeny Web systems. Within the monocots Pandanales are grouped in the lilioid monocots where they are in a sister group relationship with the Dioscoreales. Historically the order has consisted of a number of different families in different systems but modern classification of the order is based primarily on molecular phylogenetics despite diverse morphology which previously placed many of the families in other groupings based on apparent similarity. Members of the order have a subtropical distribution and includes palms, trees, shrubs, and vines as well as herbaceous plants. The order consists of 5 families, 36 genera and about 1,300 species.
Document 6: Calamus (palm): Calamus is a genus of the palm family Arecaceae. These are among several genera known as rattan palms. There are an estimated 400 species in this genus, all native to tropical and subtropical Asia, Africa, and Australia. They are mostly leaf-climbing lianas with slender, reedy stems. To aid scrambling some species have evolved hooks on the underside of the midrib, or more commonly by modified "pinnae" or tendrils in the form of stout, backward-pointing spines. These stems may grow to lengths of 200 metres.
Document 7: Polygonum erectum: Polygonum erectum is a North American species of annual plant species in the buckwheat family, with upright or ascending stems, called erect knotweed. It was once cultivated for food by Native Americans as part of the group of crops known as the Eastern Agricultural Complex. It is found primarily in the northeastern and north-central parts of the United States, but with scattered populations in other parts of the US and also in Canada.
Document 8: Pandanus tectorius: Pandanus tectorius is a species of "Pandanus" (screwpine) that is native to Malesia, eastern Australia, and the Pacific Islands. It grows in the coastal lowlands typically near the edge of the ocean. Common names in English include Tahitian screwpine, thatch screwpine., hala tree; pandanus, and pu hala in Hawaiian. The fruit is sometimes known as hala fruit.
Document 9: Phoenix (plant): Phoenix is a genus of 14 species of palms, native to an area starting from the Canary Islands in the west, across northern and central Africa, to the extreme southeast of Europe (Crete), and continuing throughout southern Asia from Turkey east to southern China and Malaysia. The diverse habitats they occupy include swamps, deserts, and mangrove sea coasts. Most "Phoenix" species originate in semiarid regions, but usually occur near high groundwater levels, rivers, or springs. The genus is unusual among members of the subfamily Coryphoideae, with it and "Arenga" being the only ones with pinnate, rather than palmate leaves.
Document 10: Eriogonum inflatum: Eriogonum inflatum, the desert trumpet, is a perennial plant of the family Polygonaceae. The plant possesses very small yellow or pink flowers and an inflated stem just below branching segments. Eriogonum: from the Greek "erion", "wool", and "gonu", "joint or knee", in reference to the hairy or woolly joints of some of the species of the genus, but not particularly "inflatum". It is found in the Mojave Desert and other deserts.
Document 11: Arecaceae: The Arecaceae are a botanical family of perennial climbers, shrubs, acaules and trees commonly known as palm trees (owing to historical usage, the family is alternatively called Palmae). They are flowering plants, a family in the monocot order Arecales. Currently 181 genera with around 2600 species are known, most of them restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts.
Document 12: Pandanus: Pandanus is a genus of monocots with some 750 accepted species. They are palm-like, dioecious trees and shrubs native to the Old World tropics and subtropics. Common names include pandan ( ), screw palm, and screw pine. They are classified in the order Pandanales, family Pandanaceae.
Document 13: Eriocaulon: Eriocaulon is a genus of about 400 species commonly known as pipeworts, of monocotyledonous flowering plants in the family Eriocaulaceae. The genus is widely distributed, with the centers of diversity for the group occurring in tropical regions, particularly southern Asia and the Americas. A few species extend to temperate regions, with ca. 10 species in the United States, mostly in the southern states from California to Florida, and only two species in Canada; China has 35 species, also mostly southern. Only one species ("E. aquaticum") occurs in Europe, where it is confined to the Atlantic Ocean coasts of Scotland and Ireland; this species also occurs in eastern North America and is thought to be a relatively recent natural colonist in Europe. In the Americas, "Eriocaulon" is the only genus in its family that occurs north of Florida. They tend to be associated with wet soils, many growing in shallow water, in wetlands, or in wet savannas like flatwoods. In wet soils, their abundance appears to be related to water levels, fire frequency, and competition from other plants such as grasses. Experiments have shown that they are weak competitors compared to many other wetland plant species. Some species can persist as buried seeds during unfavorable conditions. The scientific name is derived from Ancient Greek εριον, "erion", meaning 'wool', and καυλός, "caulos", meaning 'stalk'.
Document 14: Eriogonum: Eriogonum is the scientific name for a genus of flowering plants in the family Polygonaceae. The genus is found in North America and is known as wild buckwheat. This is a highly species-rich genus, and indications are that active speciation is continuing. It includes some common wildflowers such as the California buckwheat ("Eriogonum fasciculatum").
Document 15: Eriogonum codium: Eriogonum codium is a species of wild buckwheat known by the common names basalt desert buckwheat and Umtanum Desert wild buckwheat. It is endemic to Washington in the United States, where it is known only from Hanford Reach National Monument in Benton County. It was discovered in 1995 during an inventory of the biodiversity of the monument and described to science in 1997.
