Very rare orchid. It
was first recorded for Pietralacroce in the Province of Ancona
in 1887 by Luigi Paolucci. The species was included three years
later in his Flora Marchigiana. In both the article and
the Flora Paolucci specifies that he found the
plant only once.
Maria Cengia-Sambo reports
big populations of this orchid near Urbino on the Cesane (Fosso
delle Donne). Repeated looking for this species at this site has
proved fruitless. The one plant still present in the herbarium
of the University of Urbino (labelled: Herbarium Athenaei
Urbinatis / Urbino - frequente nei dintorni / maggio 1922 /
racc. Dssa M. Sambo) is, however, not O. tenthredinifera.
The specimen is a well-preserved robust plant of 18,5 cm with
five flowers. The petals are long and pointed, and the column is
pointed. The labellum has an elaborate speculum, very prominent
and pointed basal protuberances, and a small and narrow appendix.
These characteristics point to O. holoserica.
Cengia-Sambo very likely confused yellow-looking O.
holoserica s.l., which are common in the area, with O.
Sandro Ballelli found the
species only once in mountain pastures on M. Casale near
Camerino in the 1980s.
Recently a single plant was found near Cantiano in the Province of
Pesaro-Urbino in 2007 by Nazzareno Simoncelli. In 2008
the plant did not flower. However, Simoncelli found the plant
flowering in both 2009 and 2010.
Three plants of O.
tenthredinifera were found near Cingoli (MC) in 2009 by Sandro Ballelli, Sabrina Cesaretti, Franco Benigni and
Franco Paolinelli found
yet another plant in the province Ancona on M. Murano on 15 May
2009. It flowered again in 2010.
Claudio Poli found a
beautiful individual on Monti del Furlo on 8 May 2013 (www.policlaudio.com).
