Three pleas to collectors – Improve your field data. What is needed are ’scientific collections’

The suggestions made above will doubtless require some more time in the field spent in studying the collections made during a day.

What we need most is well-documented, rich, fertile collections for scientific pursuit. c/o Rijksherbarium, Leiden C.G.G.J. van Steenis
