Taille/poids :
La Potentille rampante est une espèce de la famille des Rosacées, herbacée, vivace, à tiges grêles, couvertes de poils diffus, courant et s’enracinant sur le sol. Les feuilles sont alternes, à cinq folioles dentées sur toute leur bordure, disposées de façon palmée (comme un éventail). Les fleurs possèdent un calice composé de cinq sépales verts soudés à leurs bases, doublé par un calicule à cinq pièces plus petites, cinq pétales jaune franc, non soudés, et un grand nombre d’étamines. La floraison s’étale de la fin du printemps aux premières gelées. Les fruits sont des akènes.
Diagnose :
La Potentille rampante est facile à déterminer, car toutes les autres espèces de potentilles sont à port dressé, à l’exception de la Potentille couchée (Potentilla anglica Laichard.), dite Potentille d’Angleterre, mais celle-ci ne présente que très peu d’enracinements de ses tiges sur le sol et ses folioles ne sont dentées qu’à leurs parties supérieures.
Biogéographique et écologie :
En France métropolitaine, cette espèce est commune dans toutes les régions. Son habitat privilégié correspond aux zones incultes, rudérales et délaissées, les friches et les décombres. Elle affectionne beaucoup les pelouses non entretenues et les pâtures humides.

The map presents a summary at the 10 x 10 km grid of the observation data for the species transmitted to the SINP. These data have been subjected to validation filters.
The map presents a reference distribution layer of the species at the scale of departments and marine sectors. The presence and absence data were established by expertise within a network of partners. This reference distribution is used in the validation process of the SINP data at the INPN level.
Corresponds to a report on the basis of at least one observation proved within a period of 10 years (20 years for little-known invertebrates) preceding the year and no presumption of extinction since obtaining the last data nor doubt on reproductive and implemented nature of this population. For migratory species, the presence indicated concerns areas of reproduction.
This status is based on one or more of the following criteria:
This point covers the absence, more difficult by nature to demonstrate than presence. This status is based on one or more of the following criteria:
This status must be assigned to a department in which the presence of the species is casual.
Particular case of absence due to a proven extinction less than a half century ago (older disappearances are treated as "no probable or definite").
In the state of knowledge, we can not comment on the presence or absence in the current department. This is the default status when not comprised in one of the previous categories or whenever there is doubt.
The map shows the global distribution of the species based on GBIF data (Global Biodiversity Information Facility).
