20 Aug 2002 Penifiler

Frequent in bogs and loch edges.

Spikelet c 7-15 mm long.  Stems c 15-35 cm tall.

Skye ID: Stem leafless and bractless as in all spike-rushes.  The top sheath (the first thing you come to as you go down the stem, fairly near the base) is cut off very obliquely, making an angle of around 45° with the stem, and is pointed.  More than 10 flowers per spikelet.  Lowest glume about a quarter as long as the spikelet, not over half as long as in E quinqueflora.

Other features: Flowers are often viviparous (see pic below) which distinguishes it at once from other Skye spike-rushes.  3 stigmas (E uniglumis and E palustris have 2)

Picture c 50 cm wide

Here the one viviparous stem in the clump has bent down to the water surface so that the young plantlets can float away.
