Plants of hybrid origin between 9 and 6(d) have been called O. bertoloniiformis O. & E. Danesch, Orchidee 22: 117 (1971); they differ from 9 chiefly in being 15-25 cm high, in having both the inner and outer perianth-segments greenish and more or less undulate, and the labellum 10-12x9-11 mm, scarcely curved upwards and without or with an inconspicuous appendage. They have 2/z = 36. Because of frequent confusion between this and 9 the distribution given above refers to both these taxa. O. bertholoniiformis is probably the more widespread, and 9 is per­ haps confined to the E. part of the range. O. promontorii O. & E. Danesch, op. cit. 258 (1971), described from S. E. Italy (Mte Gargano), is probably of hybrid origin between 9 and O. gar­ ganica (vide 6). It has 2ft = 36, 37, 38.
