Before making any collections make sure that they will be justified and can be submitted to an acceptable ‘Determiner’, to decide the ID. If you are not a member of one of the specialist societies first enquiries are possibly best addressed to the British Museum Natural History (BMNH), South Kensington.
Samples should be –
- Collected early in the year, before plants are mostly in seed.
- From plants not stressed, mown, grazed, shaded or otherwise distorted.
- With examples of late budding and flowering scapes.
