Records of Rumex graminifolius from Alaska in most cases refer to R. beringensis and R. krausei. The occurrence of typical R. graminifolius in northwestern North America remains uncertain. Some literature records of R. acetosella from northeastern North America (Greenland, Labrador, Newfoundland) may refer to R. graminifolius or R. acetosella subsp. arenicola. Rumex graminifolius was reported from Newfoundland also by M. L. Fernald (1950), but that record requires confirmation.

Some plants from northeastern Eurasia (northeastern Russian Far East and northern Siberia) are known in Russian literature as Rumex aureostigmaticus Komarov [Acetosella aureostigmatica (Komarov) Tzvelev], R. acetosella var. subspathulatus Trautvetter, or R. graminifolius var. subspathulatus (Trautvetter) Tolmatchew (see A. I. Tolmachew 1966; N. N. Tzvelev 1989b). They differ from R. graminifolius in having narrower inner tepals and wider spatulate leaves, usually without basal lobes. I have seen only one North American collection approaching this entity. Some specimens (mostly immature or staminate plants) from western Alaska differ from both R. graminifolius and R. beringensis in their habit; they need additional study. Some chromosome counts different from the most typical number (2n = 56) that have been reported for R. graminifolius in the broad sense from northeastern Russian Far East by several Russian authors (see references in Tzvelev) most probably also refer to R. aureostigmaticus. It is also possible that arctic and subarctic plants identified by various authors as R. aureostigmaticus, R. acetosella var. subspathulatus, R. graminifolius var. subspathulatus, and R. acetosella subsp. arenicola belong to one polymorphic complex of plants intermediate between R. acetosella and R. graminifolius.

Rumex graminifolius ( anglais )

fourni par wikipedia EN

Rumex graminifolius, common name grassleaf sorrel,[2] is a species of the genus Rumex and the knotweed family Polygonaceae.

Description

Rumex graminifolius is a slender perennial plant that grows from 0.1 m to 0.5 m high, with roots that run right below the surface, as well as a skinny stems and edible pointy, flat leaves. The leaves, when consumed raw, have a bitter taste. The lower leaves have 4 to 6 centimeters in length with long petioles and a membranous ocrea formed of fused, sheathing stipules. The upper ones are inflorescences, flowers and frequently become a bright reddish color. It has whorled spikes of reddish-green flowers, which bloom in late spring-summer.[4]

Distribution and habitat

Rumex graminifolius is found is arctic regions and costal rocks throughout Northern North America, Alaska and North Europe. It can grow in acid, neutral and basic soils yet prefers moist soil. It can also grow in semi-shade or no shade.[5]

Taxononmy

Rudolph, Johann Heinrich. Transactions of the Linnean Society of London 10(2): 264, pl. 10. 1811. (7 Sept 1811)[6]

Uses

This species is generally used as food plants by the larvae of a number of Lepidoptera species, and are the only host plants of Lycaena rubidus.

Rumex graminifolius J.H.Rudolph ex Lamb. es una especie de plantas de la familia de las poligonáceas.[1]

Distribución y hábitat

Habita en las rocas costeras y las regiones árticas de Terranova en Norteamérica.

Descripción

Es una planta perenne que puede llegar a crecer desde los 0,1 metros a 0,5 metros.

Propiedades

Las plantas pueden contener bastante altos niveles de ácido oxálico, que es lo que da a las hojas de muchos miembros de este género un aroma ácido de limón. Perfectamente aceptado en pequeñas cantidades, las hojas no deben ser consumidos en grandes cantidades, puesto que el ácido oxálico puede bloquear otros nutrientes en los alimentos, especialmente de calcio, lo que provoca las deficiencias minerales. El contenido en ácido oxálico se reduce si la planta se cocina. Las personas con una tendencia a reumatismo, artritis, gota, cálculos renales o hiperacidez deben tener especial precaución si se incluye esta planta en su dieta ya que puede agravar su condición

Tenonsuolaheinä ( finnois )

fourni par wikipedia FI

Tenonsuolaheinä (Rumex graminifolius) on levinneisyydeltään pohjoinen hierakkalaji.

Ulkonäkö

Tenonsuolaheinä on monivuotinen ruoho, joka kasvaa 5–25 senttimetriä korkeaksi. Se kasvaa usein mätästävästi. Juurakko on pysty ja vanhojen lehtien jäänteiden peittämä. Laji muistuttaa pientä ahosuolaheinää, mutta lehdet ovat heinämäiset, tyviliuskattomat ja tasasoukan kapeat, 2–4 millimetriä.[1][2]

Levinneisyys

Tenonsuolaheinä esiintyy varmasti Pohjoismaiden pohjoisosassa Suomessa ja Norjassa[1], Grönlannissa ja Alaskassa. Tiedot Kanadan Newfoundlandista ja Pohjois-Venäjältä kuuluvat mahdollisesti hyvin samankaltaisiin lähilajeihin.[3][4]

Suomessa tenonsuolaheinä kasvaa harvinaisena Inarissa ja Utsjoella Tenojoen laakson soraisilla järven- ja joenrannoilla.[2][5] Laji on Suomen uhanalaisuusluokituksessa silmälläpidettävä.[6]
