PORTULACACEAE
273. Portulaca oleracea L., Sp. Pl.: 445 (1753) subsp. oleracea
The archetype plant growing in several regions. Recently distinguished in infraspecific ranks.
Unknown origin (Walters 1964). The taxon of this entry represents the first subspecies to have
reached the Mediterranean basin; the presence of other subspecies is more recent (Danin & al.
1978). Variants and similar are taxonomically and caryologically distinguished to be treated at
the rank of species according to Ricceri & Arrigoni (2000): here we follow the approach of
Danin & al. (1978). – Fields, gardens, uncultivated ground. – Everywhere in the region. – CC.
274. Portulaca oleracea subsp. stellata Danin & H. G. Baker in Israel J. Bot. 27: 198

Macedony, Sapin (Danin & al. 1978.). In Spain confined in the Provinces of Cordoba, Sevilla
