It had been indicated for Gargano “Nelle arene di spiaggia a sud di Vieste (spiaggia del Castello) fino a Torre del Ponte” by A. Béguinot in 1902, as first record for Puglia (Béguinot 1909), and at Lago di Varano by Fenaroli (1974). At Laghi Alimini it was reported sub Carex paludosa Gooden. by Gehu and Biondi (1988), in the same communities where these specimens were found. L. Forte, N. Costanza Chenopodium pedunculare Bertol.

(Con- volvulaceae) —- CAM: Species to be excluded from the flora of Campania. Convolvulus tricolor subsp. meonanthus and C. tricolor subsp. tricolor were both in- dicated for the Campi Flegrei at Monte di Cuma by Terracciano (1917, respectively sub C. meonanthus Hoftm. et Link and sub C. tricolor Linn.), based on two specimens housed in NAP. Motti and Ricciardi (2005, sub C. meonanthus and C. tricolor) regarded these re- cords as very doubtful, but they did not cite any of the above-mentioned specimens, which actually are to be referred to C. tricolor subsp. cupanianus. The same taxon might have been photographed by De Santis (2007) for Castellabate (Cilento, Salerno), but no specimen is available and the population has no longer been found (De Santis, pers. comm.). E. Del Guacchio, A. De Luca Erysimum crassistylum C.Presl subsp. verresianum Peccenini & Polatschek (Bras- sicaceae) + PIE: Mompantero (Torino), Val di Susa, Localita Seghino (WGS84: 45.144086°N, 7.066062°E), praterie xeriche mosaicate a boschi di Quercus pubescens e arbusteti xero- fili a Prunus spinosa e Ligustrum vulgare, 706 m, 18 May 2024, M. Lonati, G. Marengo (FI). — Subspecies new for the flora of Piemonte. This subspecies is considered endemic to Valle D’Aosta, where it occurs on the left side of the lower Dora Baltea valley, from Saint Pierre to Bard (Peccenini and Polatschek 2014). The samples collected in Mompantero confirm the extension of the species distri- bution range also in Piemonte, where it is widespread within the xerothermic grasslands of the Valle di Susa, specifically between the municipalities of Foresto and Giaglione. The record of E. diffusum Ehrh. (Braun-Blanquet 1961, sub E. canescens) for the same locality reported here is incorrect and should be referred to E. crassistylum subsp. verresianum. M. Lonati, G. Marengo Euphorbia cyparissias L. (Euphorbiaceae) + PUG: Lesina (Foggia), lungo la Strada Statale 693 presso loc.

Lonati (FI). — Species new for the flora of Liguria. Notulae to the Italian native vascular flora: 18 101 In the collection area, this species is widely distributed across the southern-facing Ligurian slope, between Monte Saccarello, the Statua del Redentore, and the Rifugio la Terza, in pastures and calcareous rocky environments. The area falls within the Ligu- rian Alps Regional Natural Park. G. Nota, M. Lonati Klasea lycopifolia (Vill.) A.Léve & D.Léve (Asteraceae) ~ EMR. Species to be excluded from the flora of Emilia-Romagna. The occurrence of this species in Emilia-Romagna is exclusively based on the find- ing of two individuals in Val Lardana and Valle del Torrente Liscato (Piacenza) by Bracchi et al. (2003): “Cimitero di Cassimoreno e Localita Pian del Soppo”. However, no herbarium specimen exists in MNSM or in other herbaria. One of us (SO) visited the localities indicated by Bracchi et al., but only individuals of Centaurea scabiosa L. have been found. Considering that Bracchi et al. (2003) stated that one of the two in- dividuals found show a branched stem with 2—5 capitula, and that K. /ycopifolia is char- acterized by a stem with a terminal solitary capitulum, we believe that the report for Emilia-Romagna should be considered erroneous. Accordingly, K. lycopifolia should be excluded from the regional flora. S. Orsenigo, F. Bartolucci, F Conti Lotus creticus L.

The shape of the calyx, often used to distinguish Lotus creticus from L. cytisoides L., is not really reliable, whereas the density of the hairs on the leaves is of greater importance together with the size of the rachis: leaves of L. creticus are very dense- ly silky-silver and the rachis is < 30% of the basal leaflets (Tison and de Foucault 2014). Lotus creticus, so far considered as doubtfully occurring in Lazio (Anzalone et. 102 Fabrizio Bartolucci et al. / Italian Botanist 18: 97-108 (2024) al. 2010; Bartolucci et al. 2024), occurs, indeed, along the Pontine coast together with Ononis variegata L., Cakile maritima Scop. subsp. maritima, Crucianella maritima L.., Lomelosia rutifolia (Vahl) Avino & P.Caputo, and Thinopyrum junceum (L.)

Cistus albidus was firstly recorded in Lazio (as native) by Iamonico (2006). Later, this species was considered as casual alien for the region (lamonico and Lorenzetti 2008; Anzalone et al. 2010; Lucchese 2017; Bartolucci et al. 2024). During the last 18 years, I visited the site in the city of Rome many times and verified that the population found in 2005 is able to sustain itself (several seedlings and young plants at different ages and tall were observed).
