Plant of the Day (June 9th, 2012) - Carex muricata L.


Today's „Plant of the Day“ is Carex muricata L. from the Cyperaceae family. In English, this plant is known as “Squarrose-Sedge” and as “Sparrige Segge” and (in past) “Stachel-Segge” in German.

C. muricata - habitus

It's a grass-like herb, which can reach heights between 40 and 90 centimetres ( 15.75 to 35.5 inches). The stalk grows upright and in dense stocks. As with the most species from the genus Carex, the stalk has a triangular shape. It's also a little bit rough. The leaves are 2-4 millimetres broad and have a grass-green colour. Their surface is also a little bit rough.

C. muricata - spikes
 
The inflorescence is a spike, which consists of 3 to 10 spiklets. These spikelets are between 2 and 4 centimetres long. They grow close together but the lower spiklets may stick out a little bit. Their beaks are between 2 and 5 millimetres long. Each spiklet has two styli. Flowering time is between May and July.


C. muricata - habitus

C. muricata is a very common sedge in Middle Europe and can be found everywhere in Germany. It prefers fresh, sandy soils and grows e. g. in loose forests, on ruderal places or on meadows with many perennials (“Hochstaudenfluren”).

Please note: in my posting about my Field trip to the Rhine, I named this species “Carex spicata Huds.” which looks very similar. However, this was a mistake and “Carex muricata L.” is correct
