Medicago lupulina, commonly known as black medick, nonesuch, or hop clover, is a plant of dry grassland belonging to the legume or clover family. Plants of the genus Medicago , or bur clovers, are closely related to the true clovers ( Trifolium ) and sweet clover ( Melilotus ). Like the true clovers, black medick has three leaflets and a small, yellow flower closely resembling those of lesser trefoil. Black medick belongs to the same genus as alfalfa. [2]

Names

The generic name Medicago is derived, via Latin medica, from Ancient Greek Μηδική (Mēdikḗ) "Median", because alfalfa was believed to have been introduced from the region of Media (now in Iran) in antiquity. The specific name lupulina means "wolf-like", and refers to the hop, or willow-wolf. Its scientific name is a translation of the common name hop clover (or hop-clover), which is also used for several members of the genus Trifolium. [3] [4]

Also spelled "medic" or "meddick", the plant is known by a number of alternate names, including nonesuch, black nonesuch, black medic clover, hop clover, hop medic, black clover, black hay, blackweed, English trefoil, hop trefoil, and yellow trefoil. Some of these names are also applied to wildflowers of the related genera Trifolium and Melilotus. [5] [6] [7] [8]

Description

Medicago lupulina is an annual or short-lived perennial plant, [9] : 168  growing each year from adventitious buds on the roots. Mature plants measure from 15 to 80 cm (6 to 31 in) in height, with fine stems often lying flat at the beginning of growth and later erecting. The leaves are compound, each with three oval leaflets, carried on a short petiole; the center leaflet usually has a longer petiole. [10] [3] The leaflets are hairy, toothed toward the tip, and differ from those of the similar Trifolium dubium in that they end in a short point. [11] : 148  [9] : 175 

Black medick has small (2–3 mm) [9] yellow flowers grouped in tight bunches (compact racemes). On larger plants the flower heads may reach 8 mm (5⁄16 in) or more. [3] The fruit is a single-seeded pod, 1.5 to 3 mm in diameter, [9] that does not open upon maturation, but hardens and turns black when ripe. Each pod contains a single amber-colored seed. [10]

Like other legumes, the roots of black medick contain nodules hosting nitrogen-fixing bacteria. Plants that survive for more than one year may develop a deep tap root. [10]

Distribution

A native of the old world, black medick is found throughout Europe, north Africa, the Near East, and most of Asia, including India, China, and Korea. It is naturalized in central Asia, Japan, South Africa, Australia, New Zealand, the United States, Canada, and much of South America. [5] Black medick is found throughout the United States, including Hawaii and Alaska. [6]

Black medick thrives in dry to moist, well-drained soils [12] containing sand, loam, or clay, and is a pioneer plant, often growing on disturbed ground. It grows in alkaline, neutral, and mildly acidic conditions. It does not grow in shady areas. [13] Black medick grows well in limestone soils and on coastal sand dunes, where it suffers less competition from the other plants, and as such is found on many islands, such as Taiwan, the Canary Islands, the Azores, and Madeira. [5] It is resistant to cold and can be found on mountains up to 1,800 meters.[ citation needed ]

Uses

Black medick is a good source of nectar for bees to use to make honey. It is frequently found in natural pastures, and may be planted in order to create artificial meadows, especially on dry land. The presence of black medick in large concentrations as a lawn weed may indicate that the soil is poor in nitrogen. However, because black medick and other clovers fix nitrogen in the soil, this deficiency can improve over time due to the presence of these plants. [5] [14]

Black medick is sometimes used as a fodder plant. Its hardiness and ability to grow in poor soils, as well as its tendency to fix nitrogen in the soil, make black medick a good choice for pasturage, although its fodder value is limited. [5] It is grazed by sheep but is not very palatable to cattle. [15]

Similar plants

Black medick may be confused with other plants that have three leaflets and small yellow flowers, such as hop trefoil (Trifolium campestre), large hop trefoil (T. aureum), lesser hop trefoil (T. dubium), and yellow woodsorrel (Oxalis stricta).

<span class="mw-page-title-main">Clover</span> Genus of legumes

Clover, also called trefoil, are plants of the genus Trifolium, consisting of about 300 species of flowering plants in the legume family Fabaceae originating in Europe. The genus has a cosmopolitan distribution with highest diversity in the temperate Northern Hemisphere, but many species also occur in South America and Africa, including at high altitudes on mountains in the tropics. They are small annual, biennial, or short-lived perennial herbaceous plants, typically growing up to 30 centimetres (12 in) tall. The leaves are trifoliate, with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx. Other closely related genera often called clovers include Melilotus and Medicago.

<span class="mw-page-title-main">Forage</span> Plant material eaten by grazing livestock

Forage is a plant material eaten by grazing livestock. Historically, the term forage has meant only plants eaten by the animals directly as pasture, crop residue, or immature cereal crops, but it is also used more loosely to include similar plants cut for fodder and carried to the animals, especially as hay or silage.

<i>Trifolium repens</i> Flowering plant, bean family Fabaceae

Trifolium repens, the white clover, is a herbaceous perennial plant in the bean family Fabaceae. It is native to Europe, including the British Isles, and central Asia and is one of the most widely cultivated types of clover. It has been widely introduced worldwide as a forage crop, and is now also common in most grassy areas of North America, Australia and New Zealand. The species includes varieties often classed as small, intermediate and large, according to height, which reflects petiole length. The term 'white clover' is applied to the species in general, 'Dutch clover' is often applied to intermediate varieties, and 'ladino clover' is applied to large varieties.

<i>Medicago truncatula</i> Species of legume

Medicago truncatula, the barrelclover, strong-spined medick, barrel medic, or barrel medick, is a small annual legume native to the Mediterranean region that is used in genomic research. It is a low-growing, clover-like plant 10–60 centimetres (3.9–23.6 in) tall with trifoliate leaves. Each leaflet is rounded, 1–2 centimetres (0.39–0.79 in) long, often with a dark spot in the center. The flowers are yellow, produced singly or in a small inflorescence of two to five together; the fruit is a small, spiny pod.

<i>Lotus corniculatus</i> Plant species in the pea family

Lotus corniculatus is a flowering plant in the pea family Fabaceae, native to grasslands in temperate Eurasia and North Africa. Common names include common bird's-foot trefoil, eggs and bacon, birdsfoot deervetch, and just bird's-foot trefoil, though the latter name is often also applied to other members of the genus.

Hop-clover is a common name for several different plants and may refer to:

<i>Trifolium arvense</i> Species of flowering plant in the bean family Fabaceae

Trifolium arvense, commonly known as the hare's-foot clover, rabbitfoot clover, stone clover or oldfield clover, is a flowering plant in the bean family Fabaceae. This species of clover is native to most of Europe, excluding the Arctic zone, and western Asia, in plain or mid-mountain habitats up to 1,600 metres (5,200 ft) altitude. It grows in dry sandy soils, both acidic and alkaline, soil with dry-mesic conditions and is typically found at the edge of fields, in wastelands, at the side of roads, on sand dunes, and opportunistically in vineyards and orchards when they are not irrigated.

<i>Trifolium campestre</i> Species of flowering plant in the bean family Fabaceae

Trifolium campestre, commonly known as hop trefoil, field clover and low hop clover, is a species of flowering plant native to Europe and western Asia, growing in dry, sandy grassland habitats, fields, woodland margins, roadsides, wastelands and cultivated land. The species name campestre means "of the fields".
