The Litardière herbarium (deposited in G) contains many types that have previously been overlooked. The aim of this work was to identify all the new Corsican taxa then to extract all the type specimens from Corsica present in that herbarium and reported by Litardière and other botanists. 97 new Corsican taxa have been identified, and for 91 taxa, 135 type specimens (including duplicates) were found. This type material has been carefully typified as 36 holo-, 49 lecto-, 2 isolecto- and 47 syntypes. 45 taxa were described by R. de Litardière himself, 30 by K. H. Zahn (for Hieracium L.), 9 by J. L. van Soest (for Taraxacum F. H. Wigg.) and 13 by other botanists (J. Arènes, J. M. C. Arvet-Touvet, J. Gamisans, R. Maire, K. Ronniger, G. Rouy, A. Saint-Yves and T. G. Yuncker). These taxa belong to 20 families and 33 genera, but about the half (48) belong to Asteraceae, and are essentially species from Taraxacum and Hieracium. Key-
