Portulaca granulato-stellulata new for El Hierro Islands( Canary Islands).

Portulaca granulato-stellulata (Poellnitz) C. Ricceri & P. V. Arrigoni is a subcosmopolitan plant of uncertain origin (DANIN et al., 1978; DANIN, 2000). It has been recently reported from Tenerife Island (DANIN & REYES-BETANCORT, 2006), the first reference for the Canary Islands, since prior to this, the taxon had not been detected from any of the Macaronesian islands. Its presence was undetected due to its inclusion within the complex Portulaca oleracea sensu lato (HANSEN & SUNDING, 1993: 170; STIERSTORFER & GAISBERG, 2006).
