Notes:— Boissier (1875) described Ph. viridifolium from Oman: “Hab. in montibus regni Mascate Arabiae (Auch. 4774!)” and cited as type the specimen collected by Aucher-Eloy 4774. Unfortunately, the original material kept in G-BOIS herbarium was lost. Therefore, a new lectotype had to be designated. We found two specimens corresponding to the original gathering kept at the G general herbarium, and we selected as the lectotype the specimen G 00300769 because it is in a good state of preservation and morphologically agrees with the protologue. We found different isolectotypes in other institutions, nearly all of them having a printed label corresponding to the original gathering “Aucher-Eloy Herbier d’Orient Nº 4774”, and some with handwritten details of collection locality “Regn. Mascate ”. However, specimens corresponding to the original gathering are slightly different:for example, the specimen P 01816448 had a handwritten label bearing the same information about collection locality and collector “In regno Mascatensi Aucher Eloy n. 4774”. Similarly, the specimen P 01816460 bears two labels: the same printed label “Aucher-Eloy Herbier d’Orient Nº 4774” with the handwritten annotation “Djebel Akadar” as well as another handwritten label that reads “Arabie (Mascat)”.
