I know that a binomial name may be followed by the name of the reader who has been the first to identify the species and to give it that binomial name.
It is not completely clear to me what the same of a botanist, zoologist etc. means if it is placed between parentheses, as in Blysmus compressus (L.) Panzer. Does it mean that Panzer gave that species the binomial name Blysmus compressus but it was Linnaeus that identified it as a species? I cannot find precise information on line, nor in my books...
Moreover, the pattern may get more complicated if we introduce the subspecies, for example another Cyperacea: Carex ferruginea Scop. subsp. macrostachys (Bertol.) Arcang.. It seems quite trivial to me that Scopoli (Scop.) identified and gave the species the name Carex ferruginea; as to the subspecies, did Arcangeli (Arcang.) named it macrostachys after that Bertoloni (Bertol.) had identified it as a subspecies?
I thank any answerer very much.
