Orobanche minor est une plante polymorphe<\/a>. Avec des teintes jaunes possibles, souvent lav\u00e9es ou vein\u00e9es de teintes violac\u00e9es. Des individus hypochromes sont courants (enti\u00e8rement clairs ou blancs).
La l\u00e8vre sup\u00e9rieure de la corolle<\/a> se situe dans le prolongement du tube. Pas de renflement, ni vraiment de redressement brusque de ce p\u00e9tale sup\u00e9rieur vers son extr\u00e9mit\u00e9 terminale. La corolle est couverte de petits poils droits.<\/p>\n\n\n\n

Les stigmates sont rouges (-brun) ou roses, parfois jaunes mais seulement si toute la plante l’est.<\/p>\n\n\n\n

\"Orobanche<\/figure>\n\n\n\n

Remarquable par les feuilles calicinales<\/a>, lanc\u00e9ol\u00e9es<\/a>, et termin\u00e9es par une longue pointe effil\u00e9e (pointe moins fine, moins filiforme que celles chez O. artemisii-campestri).<\/p>\n\n\n\n

Noter que les filets staminaux<\/a> commencent \u00e0 2-3 mm de la base de la corolle. Ils sont velus, mais peu et \u00e0 la base. La l\u00e8vre inf\u00e9rieure ne poss\u00e8de pas de poils glanduleux. Ces crit\u00e8res de d\u00e9terminations sont ceux qui sont d\u00e9terminants. Mais ne peuvent partout \u00eatre utilis\u00e9s (voir statuts un peu plus bas).<\/mark><\/strong><\/p>\n\n\n\n

Origine et position taxonomique:<\/strong><\/h2>\n\n\n\n

Les orobanches forment un genre originaire d’Asie occidentale. Celle-ci semble provenir de m\u00e9diterran\u00e9e. En particulier en ce qui concerne cette esp\u00e8ce, il peut y avoir quelques difficult\u00e9s.<\/p>\n\n\n\n

Les diff\u00e9rentes sous-esp\u00e8ces<\/a> cit\u00e9es semblent devoir \u00eatre rapport\u00e9es \u00e0 des formes<\/a>.<\/p>\n\n\n\n

Sur la base d’An account of common Broomrape in the british Island<\/em>, parue dans British and Irish Botany en 2020. Article portant des conclusions diff\u00e9rentes sur les rangs \u00e0 attribuer … Et sous r\u00e9serve qu’il n’y ait pas d’autres formes (vari\u00e9t\u00e9s ou sous-esp\u00e8ce) en Ile de France … L’absence de glande sur la tige, la couleur des fleurs, la densit\u00e9 florale et qu’elle ne semble pas pousser en touffe … oriente vers l’id\u00e9e que l’exemplaire photographi\u00e9 pourrait \u00eatre de la vari\u00e9t\u00e9 (ou de la forme) autonyme.<\/p>\n\n\n\n

Ecologie:<\/strong><\/h2>\n\n\n\n

Plante totalement d\u00e9pendante de son h\u00f4te<\/a>.<\/p>\n\n\n\n

Orobanche minor accepte de nombreux h\u00f4tes. A proximit\u00e9 imm\u00e9diate: Plants d’Origanum vulgare<\/a>, un jeune plant de Lepidium draba<\/a>, et une rosette de Plantago lanceolata<\/a> o\u00f9 elle semble avoir pris \u00ab\u00a0pied su\u00e7oir\u00a0\u00bb.
Se trouve beaucoup sur Trifolium et autres Fabaceae, les Apiaceae, ainsi que sur Plantago \u2026<\/p>\n\n\n\n

STATUTS (consult\u00e9s le 17\/05\/2025)
Quasiment menac\u00e9e en Alsace (crit\u00e8re pr. D2)

D\u00e9terminante Znieff<\/a> en Champagne-Ardenne et en Picardie, et Pays de la Loire.<\/mark><\/p>\n\n\n\n

La plante ne porte sinon que peu d’inqui\u00e9tudes, m\u00eame si populations d\u00e9croissantes (parfois croissantes dans les communaut\u00e9s secondaires cultiv\u00e9es ?)<\/p>\n\n\n\n

HABITAT<\/p>\n\n\n\n

Plante m\u00e9sophile, m\u00e9sox\u00e9rophile; friches, prairies et cultures du tr\u00e8fle; et communaut\u00e9s littorales.<\/p>\n\n\n\n

La g\u00e9ologie de ce parc (selon les couches harmonis\u00e9es du site BRGM infoterre) pr\u00e9sente du sable de Beauchamps et du sable du val d’Oise (ou d’Auvers), coup\u00e9e d’une large langue de calcaire de Saint-Ouen. Les reliefs sont constitu\u00e9 des remblais de l’A86. Ici au bord de l’un de ses reliefs, sans doute un tout petit poil plus haut que le Carex hirta<\/a> qui se trouve un peu plus loin. Mais vis \u00e0 vis de la topographie g\u00e9n\u00e9rale de l’\u00eele, a priori le sous-sol n’est pas franchement concern\u00e9 massivement par les remblais d’autoroute.
