Two late fl owering specimens from the Ophrys incubacea group were observed, the fi rst specimen on 11th May
2016 and the second on 19th May 2016 on limestone in the area of Veli Badin above Sočerga, SW Slovenia. Floral
macro-morphological characteristics were as follows: very lax infl orescence with small fl owers, dark reddish-brown,
horizontally aligned lip. The lip was slightly convex, without basal swellings, and with hairless, orange-brown border
of the lip (rim) curved upwards. Stigmatic cavity was concolourous with the lip, higher than broader, strongly constricted at the base. Speculum was glossy, dark bluish, edged whitish, π shaped, not branched. Due to the macro-morphological characteristics and late beginning of fl owering phase, two specimens were determined as Ophrys illyrica S.Hertel & S.Hertel (Orchidaceae), a new bee orchid species in the Slovenian flora.

In the paper authors present the distribution of the Butterfl y orchid (Anacamptis papilionacea) in Slovenia. For
Slovenia and the neighboring regions, this species was already mentioned by Fleischmann (1844), Marchesetti
(1896) and Pospichal (1897). Since the species discovery in the 20
century (1975 by prof. T. Wraber), this orchid
species was observed on few locations in Istria and Vipavska dolina. Two new localities are presented, the fi rst near
the settlement of Sv. Anton in Istria on fl ysch, and the second in the continental, NE Slovenia in the Goričko region
okovci). According to the available data, the locality in Goričko is the northernmost point in the species distribution
range.

the climate changes may have pushed the species far into continental Slovenia. In Slovenia the species remains rare;
the orchid is present with only a few plants per each locality and usually growing in the vicinity of Green winged
orchid specimens (Anacamptis morio) which enable hybridization of two species.
