The sedge survey
Dr Paul Ashton and colleagues at Edge Hill University are undertaking research into the leaf anatomy of Carex with the aim of comparing phylogenies from leaf anatomy with those derived from DNA.
We are seeking samples from around the country.
For a single species a maximum of five samples in total but no more than three of same species per site. If collecting same species from a single site please ensure a minimum 10 m distance between sample plants.
No limits on number of species collected. Any at all would be much appreciated.
Collect 5-10 cm of mature vegetative leaf approximately half way along the leaf (smaller samples OK from very small species). Please ensure it is a vegetative leaf, not one on the flowering culm.
You can collect leaf sections from up to 3 plants in a site, but make sure they are at least 10 m apart (i.e. separate populations).
Keep the samples in wet kitchen roll inside plastic bag, where they will keep in a fridge for a few days before sending.
Label specimens with the following details:
- the name of the species
- the site
- the vice county number
- the grid reference
- the date of collection
- the collector
No limit on number of species collected at any one site.
It is best to cut the leaves, not tear them as that can cause damage.
Post specimens to:-
