The article officially confirming the presence of the species in Portugal can be consulted here:

Vista de First record of Teucrium aristatum Pérez Lara (Lamiaceae) in Portugal
revistas.uma.es

The species was discovered by João Neiva & Duarte Frade in Tavira, in the Algarve, where it occurs on clay soils that are temporarily flooded. It can be easily distinguished from all other Teucrium species in Portugal as it is the only annual species with bluish-violet flowers and aristate calyces.

New species for the Flora of Portugal!

The presence of Teucrium aristatum has recently been recorded in #Portugal. This small, rare annual plant was previously known only from a few locations in Spain and France and is considered globally threatened. 🌱

A new species, Linaria almadensis, has been described from the cliffs of Gargalo do Tejo, in Almada, just across from Lisbon. Although first collected in 1843, it was only recently recognized as distinct by João Farminhão during a taxonomic revision.
