Spirogyra
Spirogyra (common names include water silk, mermaid's tressses, and blanket weed) is a genus of filamentous charophyte green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is diagnostic of the genus. It is commonly found in freshwater areas, and there are more than 400 species of Spirogyra in the world.Spirogyra measures approximately 10 to 100 μm in width and may grow to several centimeters in length.
General characteristics
Spirogyra is very common in relatively clean eutrophic water, developing slimy filamentous green masses. In spring Spirogyra grows under water, but when there is enough sunlight and warmth they produce large amounts of oxygen, adhering as bubbles between the tangled filaments. The filamentous masses come to the surface and become visible as slimy green mats. Mougeotia and Zygnema are often found tangled together.
Reproduction
Spirogyra can reproduce both sexually and asexually. In vegetative reproduction, fragmentation takes place, and Spirogyra simply undergoes the intercalary mitosis to form new filaments.

Spirogyra (band)
Spirogyra are a British folk/prog band that recorded three albums between 1971 and 1973, with further original albums in 2009 and 2011.
History
Martin Cockerham (vocals/guitar) and Mark Francis originally formed Spirogyra as a duo in Bolton, Lancashire in the summer of 1967.
When Martin went to the University of Kent at Canterbury in December 1969 he expanded the band to include fellow students Barbara Gaskin (vocals), Steve Borrill (bass guitar), and Julian Cusack (violin). They were soon spotted by student union entertainments officer Max Hole, who offered to manage them and got them a recording contract with B&C Records. Their debut album, St. Radigunds, was named after the street that their student house was on. It established them as a cult act on the underground club circuit, and sold respectably. Its follow-up, 1972's Old Boot Wine, appeared on Peg Records and showcased a harder-edged sound than their predominantly acoustic debut. After the release of Old Boot Wine, the band was pared back to the duo of Cockerham and Gaskin, who were by now romantically involved. Their final album, Bells, Boots and Shambles, appeared on Polydor in April 1973 and sold poorly.

Counting The Cars
by: SpirogyraI'm counting the number of cars
Rolling into my life
Broken by alibis
Running from all those lies
Watching a number of dreams
Flowing away from me
Bum lifts from heavy loads
Burn wheels on southern roads
Feel the distance that I put between
Me and my childhood
Hang on to what remains
Leave trails of broken chains
High tail for Spanish Mains
Feeling I'm lost in my way
Too proud to lift my eyes and say
Life's not the same as I
Thought that it might have been
Heard a lot of places such as these
I remember stories, pirates, the seas, the breeze
Bum lifts from heavy loads
