When: 2010-07-31

Collection location: Parque de Monsanto, Lisboa, Portugal [Click for map]

Who: zaca

No specimen available

I had some trouble in realizing the spot tests, because the KC+ red-purple reaction was fleeting. Since I wanted to registred it in a photograph, I had to perform the tests several times, but at the end I succeeded (see last photo attached). Then I came to the name of the species that I’m proposing. As reccomended in the reference given, I made the test for oxalic acid and the taste was very bitter.
