Morettia asperrima Boiss. in Ann. Sci. Nat., Bot. ser. 2, 17: 60. 1842.

Type: “[Aucher-Eloy] N. 4102, Mascate ”.

Holotypus: OMAN: “ Mascate ”, s.d., Aucher-Eloy 4102 (G-BOIS [G00332021]; iso-: BM [BM000583729], G [G00371891, G00371892], K [K000693515], MO [MO1617736], P [P00747584], W [W0075721]) .

= Morettia philaeana (Delile) DC., Syst. Nat. 2: 426. 1821.

Notes. – Because none of the four cited isotypes was examined by Boissier, the unicate in G-BOIS is recognized as the holotype despite some might erroneously interpret the listing by STORK & WÜEST (1980: 254) as lectotypification.

Boissier in Flora Orientalis reduced Morettia asperrima to synonymy of M. philaeana .
