Question: Are  Syagrus and Ammobium both perennials?

full_context: Document 1: Lactuca perennis: Lactuca perennis, common names: mountain lettuce, blue lettuce or perennial lettuce, is a perennial herbaceous plant species belonging to the genus "Lactuca" of the daisy family. It is widespread across most of central and southern Europe.
Document 2: Aeonium glutinosum: Aeonium glutinosum is a species of flowering plant in the family "Crassulaceae". It has fairly thick leaves and its appearance varies depending on its growing conditions. One characteristic is the very sticky stem of the inflorescence. The main flower is shown but small stalks with flowers continue to appear for several months
Document 3: Ammi (plant): Ammi is a genus of 3 to 6 species of plants in the Apiaceae family. They are native to southern Europe, northern Africa and Southwest Asia. "Ammi spp." (Bishops weed) is prohibited by the Australian New Zealand Food Standards code under standard 1.4.4 due to active constituents:
Document 4: Copernicia: Copernicia is a genus of palms, native to South America and the Greater Antilles. Of the known species and nothospecies (hybrids), 22 of the 27 are endemic to Cuba. They are fan palms (Arecaceae tribe Corypheae), with the leaves with a bare petiole terminating in a rounded fan of numerous leaflets. The species are small to medium-sized trees growing to 5-30 m tall, typically occurring close to streams and rivers in savanna habitats.Govaerts, R. & Dransfield, J. (2005). World Checklist of Palms: 1-223. The Board of Trustees of the Royal Botanic Gardens, Kew.
Document 5: Antennaria: Antennaria is a genus of herbaceous perennial plants in the family Asteraceae, native to temperate regions of the Northern Hemisphere, with one species ("A. chilensis") in temperate southern South America; the highest species diversity is in North America. Common names include catsfoot or cat's-foot, pussytoes and everlasting.
Document 6: Sago palm: Sago palm is a common name for several plants which are used to produce a starchy food known as sago. Sago palms may be "true palms" in the family Arecaceae, or cycads with a palm like appearance. Sago produced from cyads must be detoxified before consumption. Plants called sago palm include:
Document 7: Aldama (plant): Aldama is a genus of flowering plants in the daisy family. 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). Recent molecular phylogenetic studies (Schilling and Panero 2011) showed that these species are within a large group that were formerly classified in the genus "Viguiera", and "Aldama" has been expanded to include a total of 118 species. "Aldama" is characterized by having a perennial herbaceous habit, a pappus usually of awns and scales, and a multiseriate involucre.
Document 8: Syagrus coronata: Syagrus coronata, the Ouricury palm or licuri palm, is a species of palm tree that plays an important role in the diets of tropical seasonally dry forest animals. It is native to eastern Brazil, ranging from the southern part of the state of Pernambuco, into the state of Bahia, south to the Jequitinhonha River in the state of Minas Gerais.
Document 9: Syagrus (plant): Syagrus is a genus of Arecaceae (palms), native to South America, with one species endemic to the Lesser Antilles. The genus is closely related to the "Cocos", or coconut genus, and many "Syagrus" species produce edible seeds similar to the coconut.
Document 10: Cycas revoluta: Cycas revoluta (Sotetsu [Japanese ソテツ], sago palm, king sago, sago cycad, Japanese sago palm), is a species of gymnosperm in the family Cycadaceae, native to southern Japan including the Ryukyu Islands. It is one of several species used for the production of sago, as well as an ornamental plant.
Document 11: Rubieae: Rubieae is a tribe of flowering plants in the Rubiaceae family and contains 969 species in 14 genera. The genus "Galium" is responsible for more than two thirds of the species in the tribe. The second largest genus is "Asperula", which contains about 200 species. Unlike the rest of the Rubiaceae family, the tribe contains predominantly perennial and annual herbs with pseudowhorls of leaves and leaflike stipules and is centered in temperate and tropical-mountain regions.
Document 12: Lytocaryum: Lytocaryum is a monoecious genus of flowering plant in the palm family endemic to Brazil where 4 species are known. Palms once classified as Microcoelum are herein included; the genus is closely related to "Syagrus", from which it is differentiated only by abundant tomentum, strongly versatile anthers, and slight epicarp, mesocarp, and endocarp differences. The name is Greek for "loose" and "nut".
Document 13: Syagrus (beetle): Syagrus is a genus of leaf beetles (family Chrysomelidae) in the subfamily Eumolpinae. They are often attracted by plants in the family Malvaceae; "Syagrus rugifrons" and "Syagrus calcaratus" are pests of cotton. The larvae of "Syagrus calcaratus" attack the roots of the plant and cause it to wilt.
Document 14: Syagrus romanzoffiana: Syagrus romanzoffiana, the queen palm or cocos palm, is a palm native to South America, from Paraguay and northern Argentina (mostly Misiones Province) north to western Brazil and northern Uruguay and west to eastern Bolivia. It had been classified within the "Cocos" genus as "Cocos plumosa", was assigned to "Arecastrum", then moved to "Syagrus". As a result of the nomenclature confusion, they often retain a previous name in popular usage. Its transfer to Syagrus and the subsumation of Arecastrum may have been premature. A genetics team led by Bee F. Gunn found that S. romanzoffiana did not group with other Syuagrus species at all, but instead with Lytocarium weddellianum. S. romanzoffiana is a medium-sized palm, quickly reaching maturity at a height of up to 15 m tall, with pinnate leaves having as many as 494 leaflets, although more typically around 300, each leaflet being around 18 inches (45 cm) in length and 1-2 inches (2.5-5 cm) in width.
Document 15: Ammobium: Ammobium is genus of perennial Asteraceae species described as a genus in 1824.
