This very rare plant grows in dark mixed woodlands at about 1000m. Flowers in August.
Rodolfo Crescentini found
a population of this orchid near Sasso Simoncello (Carpegna) in 1989.
This population has been remarkably stable over the last 20
years. Notwithstanding intensive logging in the area, the
species has survived here.
For M. Sibillini there is
a record in the herbarium of the Centro Ricerche
Floristiche Marche (PESA), of which I have no further
geographical indications.
It has also been recorded
for the Emilia-Romagna (Savelli, Alesandrini,Liverani) and
Abbruzzo (Conti & Pellegrini). In these Regions the species is
rare too.
A limited population of
very small single plants (not growing in clumps) was found on M. Catria
in August 2011. These plants might well corrispond to E.
purpurata var. pollinensis (see pictures below).
