Helleborine white sent on April 25, 2012 (0:32) by Roberto Marini. 4 comments, 1258 views.

, 1/500 f/6.3, ISO 200, tripod. Specie: Cephalanthera damasonium

E' un'orchidea molto diffusa nel Parco del Curone (Lecco), che in primavera spicca elegante e slanciata nei prati terrazzati ben esposti e nelle radure boschive soleggiate, su terreni calcarei. E' alta 20-45 cm, ha un rizoma breve con numerose radici carnose e fusti eretti con scaglie alla base, fogliosi fino all'infiorescenza. Le foglie sono numerose, alterne, quasi erette, lunghe e lanceolate. All'apice, il fusto porta un'infiorescenza a spiga con numerosi fiori bianchi, che in genere non si aprono completamente. Il labello è corto, concavo con lobi laterali triangolari, seminascosto dai tepali esterni più lunghi ed appuntiti, con una piccola macchia aranciata alla fauce. Dal momento che spesso non viene riconosciuta come orchidea e viene raccolta in mazzetti, ricordiamo che è una specie assolutamente vietata. Il frutto è una capsula deiscente contenente numerosissimi semi. Particolarità: ?Il nome del genere Cephalanthera deriva dal greco: "kefale" che significa "testa" e sta ad indicare la forma del fiore che è piuttosto arrotondata, come una testa. Il nome della specie longifolia si riferisce alle lunghe foglie della pianta. ?I fiori del genere Cephalanthera sono privi di nettare e vengono impollinati da imenotteri che scambiano le creste gialle presenti sul labello per stami ricchi di polline. La riproduzione avviene sia per via sessuata (tramite gli insetti), sia per via vegetativa attraverso i rizomi che emettono gemme in grado di generare nuovi individui. E' piuttosto diffusa anche l'autofecondazione (autogamia) soprattutto in Cephalanthera damasonium. Protezione rigorosa

hello teresa. of these flowers do not see many of the park and hit me as I have found the front. then the site of the park I documented and I copied everything. I have basically seen the first buds appear and every time I was in the area I have admired throughout its development until yesterday that it was practically without flowers.

“ how do you get to the bottom of this ... "confused"? „

watch the shooting data, with the macro f 6.3, enough to open a few meters away lying in the grass with the law and subject only to fire him. the rest is blurred, what is blurred grass in front of the subject.
