JACQUIN NAMES, SOME NOTES ON THEIR TYPIFICATION

Summary Beautiful coloured plates illustrate many of the new plant species described by Jacquin just about two centuries ago. For further detail than can be seen in the plates, it is necessary to find “Jacquin types,” actual specimens used at the time by Jacquin. Today there is no single “Jacquin Herbarium” but his specimens are to be found at Vienna, in the Linnaean Herbarium, in the British Museum (N.H.), and some are dispersed in other European herbaria. Many botanists of that day exchanged materials very widely, and it is more likely that one can determine the type than the type locality for a Jacquin species. But in some cases it may be possible to show that Jacquin got his material through an official botanical expedition or through a specific individual. Good samples of N. K. Jacquin's handwriting are to be seen in the sheets of the Linnaean Herbarium which is available on microfiche. Many of the Jacquin sheets in the Natural History Museum in Vienna were relabelled by J. F. Jacquin, the son, in a characteristic left‐hand corner script.
