Each species or variety has one or more galleries; names are arranged 
alphabetically. Within each gallery I indicated what collection was used and where that specimen is located, providing whenever possible a link to the original online information (e.g. label content or photograph of the entire herbarium sheet) made available by various herbaria on their websites. Some galleries are better than others: do not forget that most of the images you see come from samples older than 100 years (or even older!). Sometimes all we had to work with was one damaged flower removed from the type collection and kindly sent in an envelope by the curators/directors of various herbaria world-wide. Other times, the type collection itself consisted only of a few more or less broken flowers, and we did not want to create more damage, especially since many taxa are known only from their type collection. For the most damaged (or unavailable) types we will try to photograph more recent, better-looking, non-type specimens.
