Dear Irina, this find is very interesting. The host is probably Heracleum spec. Tzvelev have named in 1957 Orobanche alsatica var. heraclei Tzvelev, nom. nud.. The stems of your plant are very scaly, a character of O. alsatica-group. Can you visit the place again to make photos of this plant in anthesis?

Dear Holger. Soon I'll be there and will try to make photos. Which parts of the plant do you like to see closer?

Dear Irina, thank for the quickly answer. I think, we need pictures of spike and close up's of flowers. The taxon on Heracleum is undescribed yet! Because of this I'am very grateful for specimen material. The possibilities of cooperation we can discus in the next time. First, it is important to save images and material. I have seen similar plants on Heracleum on this web page. There, the plants were yellow. Many thanks for your support. Holger
