SUMMARY -Chromosome numbers and karyotypes in some Orchid taxa are presented. In numerous populations of Orchis coriophora subsp. fragrans, chromosome counts yielded 2n = 36. At MI in EMC, there are usually 18 bivalents. However, we observed 16 bivalents + 2 trivalents in a few specimens. A specimen of 0. coriophora found near Mattinata was a triploid with 2n = 3x =54. A karyological study of Barlia robertiana revealed a remarkable karyomorphology compared to Himantoglossum hircinum. A similar situation was found within the Orchis genus when comparing 0. tridentata with 0. lactea, and within the Serapias genus when comparing S. vomeracea subsp. vomeracea with S. vomeracea subsp. laxiflora. Karyological correlations in some Orchid genera are discussed.

“…Orchis italica and O. anthropophora are closely related (BATEMAN et al 2003), have same chromosome number (2n = 42) (QUEIROS 1985, CAUWET-MARC and BALAYER 1986, BIANCO et al 1987, COSTANTINIDIS et al 1997) and have been both included in the O. militaris (DELFORGE 2005) or »anthropomorphic« group (BATEMAN et al 2003). Orchis italica show a pendent lip, deeply tri-lobed and with a cylindrical spur, while, O. anthropophora has a narrow lip and, differently from all the others Orchis species, it lacks a spur (DELFORGE 2005).…”

-The nuclear ribosomal DNA was used to identify the orchid mycorrhizal fungi found in roots of Orchis xbivonae and its parental species Orchis anthropophora and Orchis italica. Polymerase chain reaction products were sequenced and identified using the expanded database. We determined that closely related Tulasnellaceae are mycorrhizal in the three orchid taxa, suggesting that the mycorrhizal partner does not impair hybrid survival. This study demonstrates that O. xbivonae displays few differences in comparison with its two parental species in identity of its associated mycorrhizal fungi, it is a short--term by-product of the hybridizing behavior of common pollinators, and thus it will not easily origin descendents with potential new genetic combinations and/or ecological preferences.

“…se différencie de la tribu des Neottiae Lindl. dont l'étude caryologique a été abordée précédemment (Cauwet-Marc et Balayer, 1984 a) Mis à part les premiers nombres chromosomiques établis sur cette espèce, l'unanimité semble s'être faite autour de x= 9 comme nombre de base chez Anacamptis pyramidalis, les populations étudiées jusqu 'ici étant tétraploïdes.…”
