Ptilotrichum cyclocarpum Boiss. in Ann. Sci. Nat., Bot. ser. 2, 17: 159. 1842.

 Phyllolepidum cyclocarpum (Boiss.) L. Cecchi in Pl. Biosystems 145: 828. 2011.

Type: “[Aucher-Eloy] N. 279 bis, Kurdistan ”.

Holotypus: TURKEY: “Monzourdag, Kurdistan”, s.d., Aucher-Eloy 279bis (G-BOIS [G00332419]; iso-: BM [BM001254082], G [G00446192], K [K000484525], P [P02272351, P06617344]) .

Notes. – Because Boissier based the species description on the unicate of Aucher-Eloy 279bis in his herbarium, that sheet has to be recognized as holotype. The isotype sheet at G belongs to the Moricand’s herbarium, and the two sheets at P were not annotated by him either (see BOISSIER, 1841a).

The generic placement of the species has fluctuated a great deal, but based on molecular phylogenetic studies by CECCHI (2011), the species is firmly placed in Phyllolepidum of the Alysseae .
