Lectotypus (designated by BOISSIER, 1867a: 192 ): GREECE : “ Creta , in saxosis Contopoura Eparch. Apocorona”, IV.1846 , Heldreich s.n. ( G-BOIS [ G00332118 ]; isolecto-: FI [ FI 010140], G [ G00371635 , G00371638 ], GOET [ GOET002583 ], K [ K000693728 , K000693749 , K000693750 ], KW [ KW000127961 ], W , WU [ W0077278 , WU0075959 ]) . Notes. – The original description of E. creticum listed from the same general locality mixed collections that belong to two species. Of these, one species has horizontally spreading to divaricate fruits, and the other has erect fruits appressed to the stem. However, Boissier in Flora Orientalis removed the species with erect-appressed fruits to E. raulinii and retained those with horizontal-divaricate fruits to E. creticum , thus indirectly “lectotypifying” the name. POLATSCHEK (1973) and POLATSCHEK & SNOGERUP (2002) further clarified the case by citing the duplicates of the original collections under the appropriate species. Although the collection Heldreich 1363 was used for plants of both species, the fruit orientation should be relied on to assign a given duplicate to one or the other species. For example, that collection number was given to lectotype of E. raulinii , but it is also given on the FI and WU isolectotypes of E. creticum .
