This small silvery herb is a subspecies of Alchemilla fischeri, and is only known from the summit of a single mountain. The leaf blades have 7 - 9 lobes and are covered with a thick layer of silvery hairs, which feel velvety to the touch (2). Plants are found growing together in a continuous silvery carpet that is around 5 x 20 - 30 metres in area (3).Top
Found on the summit of Mount Oku in Cameroon, West Africa (1).Top
Inhabits rocky grassland and scrub at around 2,800 - 3,000 metres above sea level (1).Top
Classified as Critically Endangered (CR - B1+2c) on the IUCN Red List 2002 (1).Top
This subspecies is particularly vulnerable, as it is only known from a single location where it is at inherent risk from any chance event such as fire. Grazing by livestock such as cattle or sheep also threaten the survival of this rare plant. Furthermore, damage by insect larvae is thought to be a problem (1).Top
Monitoring of the existing population in order to determine whether it is undergoing a decline is urgently needed (1).Top

- A small, non-woody, seed bearing plant in which all the aerial parts die back at the end of each growing season.
- A different race of a species, which is geographically separated from other populations of that species.
- Vegetative reproduction
- Type of asexual reproduction (reproduction without recombination of genetic material) that results in the propagation of plants using only the vegetative tissues such as leaves or stems. The resulting plant is genetically identical to the original plant. A well-known example of this is the reproduction of strawberry plants from 'runners'.
