This plant is brand new to Marshside, never before seen here (but not spotted by your Author). An annual, procumbent or erect, to 90cm. The stalks are very long and only sparsely and intermittently populated with leaves, flowers or fruit.

The components are spread along the stems with long comensurate gaps betweem the elements (leaves/flowers/fruit).

The leaves are of various sizes, but usually either elongated triangular or bricklayers-trowel / kite in shape (trullate)

The veins in a leaf seem to be very few and irregular.

The fruits are fairly large, to large, varying in size but in small loose groups. The smaller bracteole pairs clasping the seed (being the fruits) are triangular or extended kite shaped with either clean edges or slightly toothed, and 5-10mm long either without a stalk or stalk up to 1mm long. Larger bracteoles are up to 25mm long and with stalks to 25mm or slightly longer.

The bracteoles of the fruit are only joined at the base. They can have none or a few 'horns' (called tubercules) on the sides, usually in pairs each side of the centreline.

A large leaf and a few of the smaller fruits, some with tubercules.

Two of the larger fruits (sticking up) with long stems and bulges near the base where the two bracteoles either side are fused at the base. These bracteoles are slightly ajar all around their edges.

A small cluster of smaller fruits with very short or no stalks (not visible).

Smaller fruits with tubercules, this time centrally arranged.

Larger long-stalked fruits. Note bulges near base. Stem is angular here.

Lower down the stem is ribbed/ridged. The nearest fruit has its pair of bracteoles well parted, showing that they are joined (or 'hinged') only at their bases.


Not to be semantically confused with : Long-stalked Rape (Brassica elongata), Long-stalked Yellow-sedge (Carex lepidocarpa), Long-stalked Crane's-bill (Geranium columbinum) or Long-stalked Pondweed (Potamogeton praelongus) [plants with similar names belonging to differing families]

Not to be mis-read, mis-pronounced or mis-spelled 'longpipes' (your Author did once but he thinks he got away with it).

Amongst Oraches - Uniquely identifiable characteristics

Distinguishing Feature : The long stalks (up to 25mm) on the larger fruits, which themselves are up to 25mm long.

This is a rare [RR] plant so it is all the more welcome to see it for the first recorded time at Marshside, just north of Southport. However, it was not spotted by your Author. It is native and occupies saltmarshes where the taller species grow.
