Oenanthe fistulosa, tubular water-dropwort, is a flowering plant in the carrot family, Apiaceae, native to Europe, North Africa and western parts of Asia. It is a declining plant of wetlands.

Description

Tubular water-dropwort is a hairless, stoloniferous perennial growing up to 80 cm tall with brittle, hollow, inflated cylindrical stems 0.5 cm in diameter, which are constricted at the nodes (hence the specific name fistulosa). The upper leaves are once to twice pinnate with simple linear leaflets; the lower ones 2-3 times pinnate, with wider, flat leaflets, more like those of other umbellifers. The leaf stalks of the upper leaves are fistular, like the stem, and longer than the pinnate leaf blade.

It flowers between July and September in northern Europe, with clusters of 2-4 umbels about 1 cm in diameter, each of which has numerous white to pinkish flowers. A distinguishing feature is that, unlike many other umbellifers, it has no bracts but only small bracteoles on the individual umbels. Plants are monoecious, with hermaphroditic and male flowers on the terminal umbels, and only male flowers on the lateral umbels. Each flower has 5 unequal petals with the larger, outer ones radiating, 5 stamens and 2 prominent styles arising from a swollen base (stylopodium) at the top of the ovary. After flowering, the flower stalks and fruits expand to form distinctive pink balls with the remains of the styles projecting in pairs from the surfaces of the cone-shaped fruits.[1][2]

The chromosome number is 2n = 22 (based on British specimens).[1]

Distribution and habitat

The global range of tubular water-dropwort is from Europe through the northern half of Africa to western parts of Asia. It occurs no further north than southern Scandinavia and is rare as an introduction beyond its natural range. In Britain and Ireland it is found mainly in the lowland eastern counties, becoming increasingly rare towards the uplands of the north and west.[1][3] In France the pattern is similar, with the main populations in the southern lowlands, becoming rarer towards the upland regions around the Alps.[4]
Botanical drawing of tubular water-dropwort

It is a wetland plant, occurring naturally in swamps and marshes along valleys and in river deltas such as the Camargue in France[5] and the Doñana National Park in Spain.[6] In well-drained agricultural landscapes it is now more likely to be found in drainage ditches, farm ponds and grazed wet meadows. In some places it is found as a halophyte in coastal dune slacks or brackish grazing marshes, as at Aiguamolls de l'Empordà in Spain[7] or on the Sefton Coast in Britain.[8][9]

It favours clean, mesotrophic water, slightly base-rich conditions, and moderately high light levels, which make it an axiophyte in most British counties.[10] In France it is an indicator of the Gratiola officinalis-Oenanthe fistulosa community in restored wetlands along the Saône river.[11]

Its Ellenberg values in Britain are L = 7, F = 9, R = 7, N = 6, and S = 0.[12]
Uses

Unlike some other water-dropworts, O. fistulosa is not notably toxic, and it is freely grazed by livestock. It is used in traditional medicine in Algeria and investigations into the essential oil show that it could have medical benefits as well as uses in deterring mosquitoes involved in transmitting Dengue fever.[13] It has even been reported as part of the traditional cuisine in parts of southern Italy.[14]
