![]() ![]() This orchid is very similar in appearance to Ophrys lutea although the plants and their. Orchids of Europe, North Africa and the Middle East (3. galilaea - Small-flowered Yellow Bee-orchid. Yellow form References Delforge, Pierre (2006). This species is pollinated by the bee Halictus marginatus. These patterns of relationships suggest that differences in pollination strategiesor in pollinator communities among geographically distant populations or other ecological conditions may lead to changes in floral morphology and biology and eventually to speciation. Orchis galilaea is a species of orchid found from southern Turkey to Israel. Differences in spur features occur between the Eastern Mediterranean Orchis anatolica and Anacamptis dinsmorei and their Western Mediterranean sister species Anacamptis caspia closely resembles the eroica morphotype of the widespread Anacamptis papilionacea. The biology and ecology of Orchis galilaea Schltr., a species endemic to Lebanon, Palestine, and Jordan, is poorly studied, a fact that hinders present and future management and conservation. Anacamptis israelitic are presents one of the rare cases of the existence of floral Batesian mimicry, while the endemic Orchis galilaea is the only species among the investigated taxa to be pollinated by sexual deceit, a strategy also implemented in the distant genus Ophrys. The evolution of some sibling species pairs seems to be related to the evolution of different pollination strategies. Although no general geographic distribution pattern may be inferred, some sister terminals either show a broad East/West distribution pattern across the Mediterranean or represent peripheral isolates from amore extended range. We found that Eastern Mediterranean orchids do not represent a monophylum, as they belong to all of the three genera into which Orchis s.l. A molecular phylogenetic investigation, based on the internal transcribed spacers(ITS) of nuclear ribosomal DNA, was undertaken on members of Anacamptis, Orchis, Neotinea, and allied genera, focussing on taxa growing in the Near East and Eastern Europe, and especially in Israel. chis militaris, Orchis purpurea, Orchis punctulata, Or- The matrix obtained from the simultaneous ITS chis galilaea, and Orchis simia the other with Orchis alignment, which was used as input for the cladistic pauciflora at the base, and then a sister group composed analysis, contained 48 taxa and 525 characters (ITS1 of Orchis mascula and. ![]()
