= Phagnalon rupestre View in CoL (L.) Candolle (1836: 396) subsp. rupestre View in CoL

Notes:— Conyza tomentosa View in CoL was described from several localities: “Alexandria, & Hadie.Arab. Tom erneb vel Mottaj”. The original material of C. tomentosa View in CoL deposited at C herbarium is a mixture of Ph. woodii View in CoL and Ph. rupestre View in CoL . Nearly all syntypes collected by Forsskål and kept at C correspond to typical Ph. rupestre View in CoL . Moreover, the specimen C10002068, included in the type database of the C herbarium, corresponds to Ph. woodii View in CoL and was collected in Kusma ( Yemen), but not in the original locality. We selected the specimen C10002069, which corresponds to Ph. rupestre View in CoL , as the lectotype. It was collected by Forsskål and better agrees with the protologue, and bears a handwritten note “nova” on the label.
