"Habitat in Europa australi, India, Ins. Ascensionis, America." RCN: 3458. Lectotype (Geesink in Blumea 17: 292. 1969): Loefling s.n. , Herb. Linn. No. 625.1 ( LINN ) . Generitype of Portulaca Linnaeus (vide Green, Prop. Brit. Bot. : 157. 1929). Current name: Portulaca oleracea L. subsp. oleracea ( Portulacaceae ). Note: Geesink stated "T[ype]: LINN (photograph seen)" and as the only sheet he could have intended is 625.1 (LINN), and it is original material for the name, this choice is accepted here. Danin & al. (in Israel J. Bot. 27: 196. 1978), however, stated "the lectotype should be chosen from the Hortus Siccus Cliffortianus material in the British Museum (Natural History!)", and applied their infraspecific nomenclature accordingly. They identified ( l.c .: 198) the LINN material (accepted here as the type) with subsp. stellata Danin & Baker . Most recent authors appear to accept Geesink's choice of type but have adopted a broad species concept.
