Malva sylvestris is a species of the mallow genus Malva in the family of Malvaceae and is considered to be the type species for the genus. Known as common mallow to English speaking Europeans,[3] it acquired the common names of cheeses, high mallow and tall mallow (mauve des bois by the French)[4] as it migrated from its native home in Western Europe, North Africa and Asia through the English speaking world.[5] M. sylvestris is a vigorously healthy plant with showy flowers of bright mauve-purple, with dark veins; a handsome plant, often standing 3 or 4 feet (1 m) high and growing freely in fields, hedgerows and in fallow fields.[6]

Habit

Description

Malva sylvestris is a spreading[3] herb,[12] which is an annual in North Africa,[7] biennial[5][8] in the Mediterranean[7] and a perennial elsewhere[7][12] Three feet (one meter) tall,[3][6] (3 meters has been observed in a wild or escaped from cultivation setting, and several cultivated plants of 2 meter or more in height[7]) with a growth habit which can be straight[8] or decumbent,[3][12] branched and covered with fine soft hairs or none at all,[8] M. sylvestris is pleasing in appearance when it first starts to flower, but as the summer advances, "the leaves lose their deep green color and the stems assume a ragged appearance".[6]

Stems and leaves: A thick, round and strong stem.[6]

The leaves are borne upon the stem,[6] are roundish,[3][6][12] and have three[5] or five to seven[6][12] or five to nine[8] shallow[3] lobes, each 2 to 4 centimeters (1 to 2 inches) long, 2 to 5 centimeters wide (1 to 2 inches)[5] and 5 to 10 centimeters (2 to 4 inches) in diameter.[12] Downy, with hairs radiating from a common center and prominent veins on the underside.[6]
Petiole either 2 to 6 centimeters (1 to 3 inches)[5] or 2 to 13 centimeters (1 to 5 or 6 inches) long.[8][12]

Flower



Flowers
Described as reddish-purple,[8] bright pinkish-purple with dark stripes[3] and bright mauve-purple,[6] the flowers of Malva sylvestris appear in axillary clusters[12] of 2 to 4[5] and form irregularly and elongated along the main stem with the flowers at the base opening first.[12]
M. sylvestris has an epicalyx (or false calyx) with oblong segments, two-thirds as long as calyx[12] or 2–3 millimeters long and 1.5 millimeters wide.[5] Its calyx is free to the middle, 3–6 millimeters long,[5] with broadly triangular lobes[5] or ovate mostly 5–7 millimeters long.[12] The flowers are 2–4 times as long as the calyx;[8]
Petals are wrinkly to veined on the backs,[8] more than 20 millimeters long[3] or 15 to 25 millimeters long [12] and 1 centimeter wide,[5] eggshaped, margin notched with a fringe of hairlike projections.[5]
Slender flower stalks[8] that are either 2 centimeters long[5] or 1 to 3 centimeters long.[12]
Ten broad carpels in axillary clusters;[8] stamen about 3 millimters long, radiating from the center with short soft hairs.[5]

Fruit
Fruits
Nutlets strongly reticulate (10–12 mericarps, usually without hair, with sharp angle between dorsal and lateral surfaces, 5–6 millimters in diameter.[3][5]
Seeds or 'cheeses,'[6] are brown to brownish green when ripe, about 2.5 millimeters long and wide[5][12] 5 to 7 millimeters in diameter[12] and are shaped like a cheese wheel which is where several of its common names came from.[citation needed]
Chromosome number
2n=42.[3]

Distribution

As a native Malva sylvestris spreads itself on waste and rough ground, by roads and railways throughout lowland England, Wales and Channel Islands, Siberia and scattered elsewhere.[3][8] It has been introduced to and has become naturalised in eastern Australia,[12] in the United States, Canada and Mexico probably escaped from cultivation.[8]

Uses

<templatestyles src="Template:Quote_box/styles.css" />

Mauve, n. F., mallow, L. malva. So named from the similarity of the color to that of the petals of common mallow, {Malva sylvestris}.

Webster's Dictionary

M. sylvestris in a 19th-century illustration

In 1931 Maud Grieve wrote that the "use of this species of Mallow has been much superseded by Marsh Mallow (Althaea officinalis), which possesses its valuable properties in a superior degree, but it is still a favourite remedy with country people where Marsh Mallow is not obtainable."[6]

Decoration
In the past, the flowers were spread on doorways and woven into garlands or chaplets for celebrating May Day.[6]
Food
The young leaves when boiled is a wholesome vegetable[6] and was eaten in several parts of Europe in the 19th century.[13]
Medicinal
M. sylvastris has been used medicinally since ancient times,[14] and is still used in modern phytotherapy.[15][16] Mucilage is present in many of the Malvaceae family including M. Sylvastris,[17][18] especially the fruit.[19] The seeds are used internally in a decoction or herbal tea[20] as a demulcent and diuretic,[13][19] and the leaves made into poultices as an emollient for external applications.[19] Mallow can also taken internally for its laxative effect.[14][16][21][15]
Other
The species has long been used as a natural yellow dye,[22] perhaps more recently, cream color, yellow and green dyes can be obtained from the plant and the seeds.[23] A tincture of the flowers can make a very sensitive test for alkalis.[6]

Subspecies

Plants previously often described as Malva sylvestris var. malaca are now considered a Cultivar Group Malva sylvestris Mauritiana Group.[7]

Cultivation

Swedish: mauretansk rödmalva, Estonian: mauri kassinaeris, Slovene: Mavretanski slezenovec, Croatian: mórmályva Malva mauritiana used to be recognized as a species whose range is Iberia, Italy and Algeria. Garden plants are often called Malva sylvestris var. mauritiana and they make a cultivar group that includes:
  • 'Bibor Felho'
  • 'Moravia'

Malva sylvestris L. Eriocarpa group
Hairy seeds and hairy stems found between Italy and the Himalayas, Central Asia and China.
Malva sylvestris L. Canescens group
Every part except for the flower is covered with dense white woolly hair, growing in the Montpellier region of France, and on the Balearic Isles. Some 19th-century botanical works called this group Malva sylvestris L. var. canescens.
Malva sylvestris L. Sterile Blue group
Vegetatively propagated pale violet-blue flowered cultivars:
  • MARINA 'Dema'
  • 'Primley Blue'

Virus
Malva vein clearing potyvirus which is transmitted by mechanical inoculation in a non-persistent manner via insects: Aphis umbrella (syn. Aphis malvae Koch) and Myzus persicae (all are Aphididae). The virus can be found in Tasmania, Brazil, the former Czechoslovakia, Germany, Israel, Italy, Portugal, California, Russia and the former Yugoslavia.[25][26]

Chemistry

M. sylvestriscontains malvin and malonylmalvin.[27] It also contains the naphtoquinone malvone A, which is also a phytoalaxin.[28]
