Dear Andrey, in our regions, that means Germany, O. kochii grows begin July, distinctly later than O. elatior (begin June). However, I think, that I will visit the place of your find in this year and we will see, if you have explore the first certain occurence of O. kochii in Germany. The question is (and my opinion), if the plants from Carel Kreutz from Nonnenbach are also O. kochii? The flowering time begin Juli (Nonnenbach: 08.07.) is for O. elatior s. str. in Germany to late.

Sorry Andrey, for O. kochii we need the host Centaurea.

In Orobanche minor are yellowish stigmas very rare. O. minor growing usually at sunny places, often in meadows and fields. The yellow plants above are O. hederae f. monochroa G. BECK, Monogr. Orob. 260. 1890. The host is clearly visible in pictures.
A remarkable characteristic of O. hederae are the more or less constricted corolla tube - also something visible in pictures.

Dear Alim,
thank you for the permission.
For a valid description of f. talassica we need a holotype, held in a serious herbar and a fully description in a scientific journal.

The infraspecific taxa hians was described by Günther Beck von Mannagetta in his monograph about Orobanche 1930 page 286.

Dear Nadeshda, the host seems to be a member of genus Medicago, but the species I don't know. I will ask a friend. Possible he help us.

Dear friends,
here is a picture of a similar plant (certainly O. caryophyllacea) from Germany (Nördlinger Ries, mt. Goldberg) http://orowiki.org/wiki/Orobanche_caryophyllacea

Yes, O. cumana is parasitic also on wild plants, especially Artemisia (f. e. A. campestris, A. ferganensis, A. fragrans, A. monogyna, A. vachanica), but also Carthamus tinctoria, Sonchus, Xanthium and several Solanaceae (Lycopersicon esculentum, Nicotiana rustica), probably also on Lamiaceae (Perilla frutescens).

Ok, I have studied the website of Online-Flora Israel. There are other plants with large corollas, named as Orobanche mutelii. Because of this for the moment I'm agree with the determination as Phelipanche mutelii, but not without doubt.

Dear friends,
Orobanche crenata s. str. and var. callieri haven't yellow stigmas. What do you think about O. elatior or O. kochii? Dear Pavel, do you have more pictures of this plant?

I forgot: The calyx halves of O. caryophyllaceae often very different 2-toothed and the front-tooth of the calyx segment ist smaller and hide under the bract. When the calyx segment seems to be entire, but not in true.

Dear Andrey,
in Middle Europe is O. caryophyllacea a common plant and - with more than 30 infraspecific taxa - very variable. I have seen many specimen of Orobanche caryophyllacea with bright white, yellowish or darker purple corollas and I'm absolutely convinced that it's O. caryophyllacea. I think, that the hairs or glands seems to be dark on the shining througt corolla.

On the other hand the entire upper lip, the shape of corolla (see fig. at Novopokrovsky) and the length and shape of calyx segments indicated that its O. vitellina.

Re: Orobanche (5 ответов, оставленных в Растения на фото)
I have also think about O. vitellina, but some characteristics are different: In O. vitellina the spike should be faily dense, the stem should be brownish yellow, the stigma should be yellow. I think we need specimens ore a detailed description of these plants for an certainly identification. But I agree, that this plant is very exceptional.

Dear Jevgeniy,
this plant is something problematic. I have seen similar plants on Heracleum and I think, its Orobanche alsatica var. heraclei TZVELEV, Fl. Azerb. VII: 591. 1957, sine lat. descr.
I'am looking for more material (specimen and pictures) to examine this plant. Do you have any specimen or further high detailed pics?

Re: Orobanche (5 ответов, оставленных в Растения на фото)
Dear Nadeshda,
yes this is O. gracilis, probably forma hians Beck. Can I use this pic for my wiki project http://orowiki.org, please (considering the copyrights of course)?

Dear Tatyana,
the flowers of this plant are very large for Ph. mutelii. It's probably Ph. aegyptiaca.

Dear friends,
I think, this is O. teucrii, but
a) is this the mostly eastern known location,
b) is the yellow stigma atypical for O. teucrii (only in f. aurea Teyber). See http://orowiki.org/wiki/Orobanche_teucrii_f._aurea
