Montia fontana, blinks is a herbaceous annual to perennial plant that grows in freshwater springs in upland regions, and in seasonally damp acid grassland in the lowlands. It is widespread throughout the world, except in southern Asia. It is rather variable in morphology, which is reflected in a complex history of taxonomy. Currently, there are three accepted subspecies which are defined largely by the appearance of the seedcoat. It is edible and consumed as a salad in some areas, but is otherwise of minimal economic impact. Because of its association with clean water habitats, it is often viewed as a species of conservation value.
Description
Blinks is an annual to perennial prostrate herb with branching stems, sometimes forming mats up to 50 cm across in short, seasonally damp grassland or floating in streams and hollows. The stems are thin (0.5 mm diameter) and reddish, sometimes rooting in water. The primary roots are fleshy and pink, and there are numerous secondary roots with fibrous hairs.
The spatulate leaves are succulent and glabrous, arranged in opposite pairs, between 2–20 mm long and 1.5–6 mm wide, with a hydathode at the tip. On some plants, particularly those floating in water, the leaves have a distinct petiole, whereas on those (mainly subsp. chondrosperma) which grow in dry grassland, the leaves narrow towards their bases and fuse with the opposite one at the stem (i.e. they are connate).

The inflorescence consists of a terminal cyme of two or three tiny white flowers 2–3 mm in diameter with five petals, two sepals, 3-5 stamens, 1-3 styles, each with one stigma.
The fruit capsules are 2 mm in diameter and contain 3 round seeds. The architecture of the seeds differentiate the four varieties of blinks.{{cite book |last1=Stace |first1=C.A. |title=New Flora of the British Isles |date=2019 |location=Suffolk |publisher=C & M Floristics |edition=4th |isbn=978-1-5272-2630-2}}{{cite book |last1=Sell |first1=Peter |last2=Murrell |first2=Gina |title=Flora of Great Britain and Ireland, vol 1 |date=2018 |publisher=Cambridge University Press |location=Cambridge|isbn=978-0-521-55335-3}}{{cite book |last1=Poland |first1=John |last2=Clement |first2=Eric |title=The Vegetative Key to the British Flora |date=2009 |publisher=John Poland |location=Southampton |isbn=978-0-9560144-0-5}}
Taxonomy
The name Montia fontana was coined by Linnaeus in 1753 in Species Plantarum, but it has had many synonyms before and since; Linnaeus lists "Montia aquatica minor", "Cameraria aquatica minor" and "Portulaca arvensis" among them.{{Cite book |last=Linnaeus |first=C. |title=Species Plantarum |year=1753 |url=https://www.biodiversitylibrary.org/item/13829#page/99/mode/1up}}{{Cite web |title=Montia fonatana L. |url=https://www.gbif.org/species/9004024 |access-date=10 February 2024 |website=Global Biodiversity Information Forum}}
The generic name Montia is a tribute to Giuseppe Monti (1682-1760), a professor of botany at Bologna.{{cite book |last1=Leighton |first1=W.A. |title=A Flora of Shropshire |date=1841 |publisher=John van Voorst |location=London}} The epithet fontana derives from the Latin fontanus, a spring, and refers to its habitat. The common name "blinks" may come from the phrase "blink and you miss it", due to its very small size, alternatively it may be from the Old English "blincan", to shine or twinkle. Other common names for it include "water blinks", "water chickweed" or (in the US) "annual water miner's lettuce".
Because blinks is such a widespread and variable species, many synonyms have been coined, and many subspecies have been described which reflect this variability. The currently accepted account is largely based on that of Max Walters in the British journal Watsonia in 1953.{{Cite journal |last=Walters |first=S.M. |date=1953 |title=Montia fontana L. |url=https://archive.org/details/wats-3p-1 |journal=Watsonia |volume=3 |pages=1–6}} In this paper he described 4 subspecies:
- subsp. fontana, which has smooth, shiny seeds 1.1-1.35 mm in diameter and occurs in very wet places worldwide, often growing as a floating plant with petiolate leaves.
- subsp. chondrosperma (Fenzl) Walters, which has less shiny seeds 1.0-1.2 mm diameter and occurs on sandy soils in lowland places. It is a small plant (~1 cm tall) with connate leaf bases.
- subsp. intermedia (Beeby) Walters, which has shiny tuberculate seeds 0.85-1.1 mm diameter and grows in very wet places in Western Europe and Australia. This is now called Montia fontana subsp. amporitana Sennen.
- subsp. variabilis Walters, which has smooth seeds 0.9-1.1 mm diameter and grows grows in wet places in Britain and possibly elsewhere. This is no longer considered a valid taxon.
Distribution and status
Blinks has an almost world-wide distribution, and it is considered a native species in most places, and in all continents except Antarctica. It is apparently considered an introduction only in Venezuela and the Falkland Islands, and it is absent only from southern Asia.{{Cite web |title=Montia fontana L. |url=https://www.gbif.org/species/9004024 |access-date=17 February 2024 |website=Global Biodiversity Information Forum}}{{Cite web |title=Montia fontana L. |url=https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:311155-2 |access-date=17 February 2024 |website=Plants of the World Online}}

Habitat and ecology
File:Montia fontana (mezenc, 43, France)2.JPG
Blinks grows in a wide range of wetland habitats, from permanently wet pools, springs and streamsides to winter-wet, sandy grassland. It mostly grows in acid places, but is tolerant of mildly alkaline conditions. Its altitudinal range in Britain is from sea level to 996 m in Coire Leachavie, Glen Affric.{{Cite book |last=Schou |first=J.C. |title=Aquatic Plants of Northern and Central Europe including Britain and Ireland |last2=Moeslund |first2=B. |last3=van de Weyer |first3=K. |publisher=Princeton University Press |year=2023 |isbn=978-0-691-25101-1 |location=Princeton, N.J.}}{{cite web |last1=Pearman |first1=D.A. |title=Altitudinal Limits of British Plants, 2021 |url=https://bsbi.org/altitudes}} The flowers are either pollinated by insects or (especially if underwater, when they are often cleistogamous) will self-pollinate.
Its Ellenberg values in Britain are L = 7, F = 9, R = 5, N = 3 and S = 0, which show that it occurs in fairly sunny places with slightly acid damp soils and low nutrient conditions. It is not tolerant of salt.{{cite book|last1=Hill|first1=M.O.|last2=Mountford|first2=J.O.|last3=Roy|first3=D.B.|last4=Bunce|first4=R.G.H.|title=Ellenberg's indicator values for British plants.

Under the European system for classifying habitats, EUNIS, Blinks is a characteristic species in three habitats, comprising four communities: C2.18 acid oligotrophic vegetation of spring brooks; C2.25 acid oligotrophic vegetation of fast-flowing stream; and D2.2C soft water spring mires, including D2.2C11 montane soft water moss springs.{{Cite web |title=Montie des fontaines |url=https://inpn.mnhn.fr/espece/cd_nom/108785 |access-date=20 February 2024 |website=Inventaire National du Patrimoine Naturel}} Within the British NVC blinks (particularly subsp. fontana) occurs in several types of upland spring-fed vegetation, most characteristically M35 Ranunculus omiophyllus-Montia fontana rills,{{cite book |last1=Rodwell |first1=J.S. |title=British Plant Communities, vol. 2: Mires and heaths|year=1991 |publisher=Cambridge University Press |location=Cambridge |isbn=0-521-39165-2}} and (mainly subsp. chondrosperma) in summer-dry, rain-fed U1 Festuca ovina-Agrostis capillaris-Rumex acetosella grassland in sandy, more lowland habitats.{{cite book |last1=Lockton |first1=Alex |last2=Whild |first2=Sarah |title=The Flora and Vegetation of Shropshire |date=2015 |publisher=Shropshire Botanical Society |location=Montford Bridge |url=https://archive.org/details/flora-and-vegetation-of-shropshire-2015|isbn=978-0-9530937-2-4}}{{cite book |last1=Trueman |first1=I.C. |last2=Poulton |first2=M.W. |last3=Hodder |first3=M.|title=The Flora of Sutton Park |date=2023 |publisher=Pisces Publications |location=Newbury |isbn=978-1-913994-09-9}}

Blinks is occasionally found in secondary populations in other habitats, such as woodland stream sides, where it has presumably been washed up, or in bowling greens or pavements after habitats have been built over.{{cite book |last1=Graham |first1=G.G. |title=The Flora and Vegetation of County Durham |date=1988 |publisher=Durham County Conservation Trust |isbn=0-905362-02-0}}{{cite book |last1=Crawley |first1=M.J. |title=The Flora of Berkshire |date=2005 |publisher=Brambleby Books |location=Harpenden |isbn=0-9543347-4-4}}

Uses
Blinks is edible and is gathered in the wild and used as a salad vegetable in Spain and Portugal, but it is not currently cultivated. It is high in fibre and is a rich source of omega-3 fatty acids.{{Cite journal |last=Tardio |first=J. |date=2011 |title=Montia fontana L.
