Growth in numbers of plant species known from Guinea and in the numbers of herbarium specimens documenting the Guinea flora. Increase over time in: (i) plant species recorded from the Republic of Guinea, plotted (dashed trace) by the date when species was first described (which may predate their first record from Guinea by many years) and (ii) herbarium specimens collected in Guinea and incorporated in the Guinea Plant Collections database, plotted (solid trace) by their year of collection.
