1. Fritillaria tubiformis Gren. & Godr. in Mém. Soc. Emul. Doubs ser. 2, 6: 13. 1855 .

≡ Fritillaria delphinensis Gren. in Gren. & Godr., Fl. France 3: 180. 1855, nom. illeg.

Lectotypus (here designated): FRANCE. Hautes Alpes: Lusette en Luz (Drome), 1847, Boullu s.n. (P! ex Herb. Grenier sub F. meleagris, rev. F. alpicola) (Fig. 1) .

Syntypi. – FRANCE. Hautes Alpes: Mt. Seuse pres Gap, VIII.1847, Verlot s.n. (P! ex Herb. Grenier, sub F. meleagris, rev. F. alpicola); Mt. Séuse près Gap, 1854, Grenier s.n. (K!) .

GRENIER & GODRON (1855) quote several syntypes for this taxon. From the localities cited in the protologue, we traced, in P and K, specimens that can be considered as original material. Among these we choose the most well-developed and well-presented as lectotype.

Taxonomic discussion. – Fritillaria tubiformis was long confused with F. meleagris L. (i.e., BERTOLONI, 1839), but it is clearly distinct from all other species from West Europe RENIER & GODRON, 1855). On the other hand, it seems close to F. latifolia Willd., widespread from Caucasus to N Turkey IX, 2001), from which it differs in having glaucous leaves (vs. shiny green) and shorter style branches. Among the taxa usually synonymized with F. tubiformis, two seem to deserve special attention ( F. delphinensis var. burnatii Planch. and F. delphinensis f. moggridgei Planch.), while others have doubtful taxonomic value (i.e., F. delphinensis var. reverchonii Rouy; ROUY, 1910). Similarly to what was done recently with the F. montana W. D. J. Koch complex (BARTOLUCCI & al., 2009; PERUZZI & al., 2009; PERUZZI & BARTOLUCCI, 2009), a biosystematic study is in progress about the F. meleagris L. complex ( F. meleagris s.l. and F. tubiformis s.l.), aiming to clarify the relationships among the taxa and their distribution.
