| Phylum | Tracheophyta |

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).

Alchemilla biology
It is thought that vegetative reproduction, from stems growing horizontally along the ground (known as stolons), may be more important in this species than sexual reproduction via seeds (3).

Species found in a similar habitat
Alchemilla status
Classified as Critically Endangered (CR - B1+2c) on the IUCN Red List 2002 (1).
TopAlchemilla threats
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).
TopAlchemilla conservation
Monitoring of the existing population in order to determine whether it is undergoing a decline is urgently needed (1).

Glossary
- Herb
- A small, non-woody, seed bearing plant in which all the aerial parts die back at the end of each growing season.
- Subspecies
- 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'.
