The Rance (French pronunciation: [ʁɑ̃s] ; Breton: Renk, [ˈrẽŋk]) is a river of northwestern France. It is 103.6 km (64.4 mi) long.[1] It flows into the English Channel between Dinard and Saint-Malo.
Before reaching the Channel, its waters are barred by a 750 metre long dam forming the Rance tidal power plant.
The river is linked to the Vilaine by means of the Canal d'Ille-et-Rance.

Hydrology and water quality[edit]
Tributaries of the Rance include:
- Croqueloir
- Clergé
- Fremeur
- Quinéford
This river has moderate turbidity and its brownish water is somewhat low in velocity due to the slight gradient of the watercourse; pH levels have been measured at 8.13[2] within the city of Dinan and electrical conductivity of the waters have tested at 33 micro-siemens per centimetre. At this reference location, summer flows are typically in the range of 14 cubic metres per second (500 cu ft/s).[citation needed]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
