This is also certainly Orobanche gamosepala. Can I use both photos of this species in a Wiki-Projekt about Orobanchaceae?

Holger, ask Mr Николай Голубев directly by e-mail

По Зернову у Orobanche gamosepala чашечка плёнчатая, цельная. Здесь же, мне кажется, чашечка кожистая, "рассечённая на два... сегмента"(?), что говорит о Orobanche raddeana.

Я вот тоже силился разглядеть там чашечку, и никак не могу согласиться с тем, что она цельная.

Кроме того, Orobanche gamosepala должна расти в лесах, а не на альпийских лугах.

This plant is truly O. gamosepala, not O. raddeana. Both species are growing on subalpine meadows and both species have yellow stigmas. O. gamosepala is parasitic on Geranium-species, O. raddeana probably on Dorycnium and Campanula. The original description of O. raddeana shows, that the corolla is regularly curved “Linea dorsalis aequaliter curvata”. The corolla on picture is distinctly curved basally and at the upper lip. The earlier neighbourhood of O. alba (O. alba var. raddeana) shows, that the corolla not distinctly differ from O. alba. A picture of a specimen you can see under http://orowiki.org. The calyx segments distinctly longer than at the plant on picture. The original description of O. gamosepala shows, that this plant is blackish-red (“Flores laxe et subalterne spicati, erecti, O. Galii magnitudinis, in sicco atro-sanguinei.”). The upper lip is helmet-like (“labio superiore galeato integro vel leviter emarginato”). I can’t clearly see, that the calyx segments on the plant are individed. They are more similar to the segments of O. gamosepala.

This question needs further clarification. If you accept the citations of Galushko for O. raddeana you should take into account his indication that the inflorescens of O. raddeana is sparsely flowered as is in this photo.

Galushko encodes O. raddeana between the species of the tribe Curvatae (alsatica, grossheimii and inulae) that is between species with regularly curved dorsal line (compare also Galusko's key point 12.) On the other hand has O. gamosepala and also the plant in the picture a clearly irregularly curved dorsal line. The flower state (laxly or dense) is for itself taken no a sufficient character.
