Modesciadium involucratum (Maire) P.Vargas & Jim. -Mejías, comb. nov.

Basionym: Trachyspermum involucratum ( Maire 1926: 186) . Lectotype (here designated):— MOROCCO. “Maroc, Marrakech, rochers calcaires du Gueliz”, 7 April 1921, Maire (P, photo!).

≡ Brachyapium involucratum (Maire) Maire (1932: 186) .

≡ Stoibrax involucratum (Maire) Burtt (1989: 146) .

Notes: —This taxon resembles superficially forms of Ammoides pusilla (Brot.) Breistroffer (1947) , with tuberculate fruits ( Nieto Feliner et al. 2003), from which it can be easily distinguished by the dimorphic bracteoles (three linear and two to three conspicuously spatulate), whereas all the bracteoles of M. involucratum are linear or linear-lanceolate. Two other alternative genera have been considered for North African Stoibrax species: Trachyspermum Link , and Brachyapium (Baill.) Maire. However , Trachyspermum is typified on T. ammi (tribe Pyramidoptereae ; Downie et al. 2010), and Brachyapium , based on Carum sect. Brachyapium Baill. , is typified on Ptychotis didyma Sond. (tribe Tordylieae ; Magee et al. 2010b).

3. Schoenoselinum Jim. -Mejías & P.Vargas, gen. nov. Type: — Schoenoselinum foeniculoides ( Maire & Wilczek 1936: 66) Jim. -Mejías & P. Vargas.

A new genus similar to Anethum and Foeniculum , from which can be distinguished by the shrubby habit and rod-like leafless flowering stems.

Etymology: —The etymology of the name comes from Schoenos “rush”, combined with the latin word Selinum , which means “celery”.

Distribution: —This monotypic genus comprises only Schoenoselinum foeniculoides (see below). It is an endemic from southwestern Morocco (from Chtouka to N Sahara) where it inhabits subcoastal ravines and rocky places on sandstones ( El Alaoui Faris & Ibn Tattou, 2007).

Schoenoselinum foeniculoides (Maire & Wilczek) Jim. -Mejías & P. Vargas, comb. nov.

Basionym:— Anethum foeniculoides Maire & Wilczek (1936: 66) . Lectoype (here designated):— MOROCCO. “Maroc, in rupestribus arenaceis secus flumen Noun infra Abouda”, 4 April 1935, Maire 2556 (P, photo!).

Notes: —The name Anethum foeniculoides was first published by Maire & Wilczek (1946), and again as a “new species” several months later by Maire (1936), which has led to some nomenclatural confusion. It was described as being similar in habit to fennel, but was included within Anethum based on the narrowly winged mericarps.
