Platanthera. bifolia ssp. latifolia
Platanthera bifolia ssp. latifolia distinguished from P. bifolia ssp. bifolia in that spur to the flowers in the middle of inflorescence often more than twice as long as the ovary. In both species are both Polini close and parallel. At the bottom of the stem sits two ovate leaves. The specimens up to 50 cm high and flowers are sitting more scattered than in P. bifolia ssp. bifolia. P. bifolia ssp. latifolia also looks more elegant and “nice” than P. bifolia ssp. bifolia.
P. bifolia ssp. latifolia requires a completely different habitat than the other two Platanthera bifolia when it grows in the forest without direct sunlight. My biggest stocks I’ve found on Jomfruland with many hundred copies on a small area.
Platanthera bifolia ssp. bifolia
These distinguished by the spur of flowers on P. bifolia ssp. bifolia middle of the inflorescence is often less than twice as long as the ovary. P. bifolia ssp. bifolia are up to 35 cm high with 12 to 25 flowers. The flowers sit closer and plant does not look so elegant. In both species sits Pollini close and parallel. P. bifolia ssp. bifolia found in bright, open wet heaths and meadows happily in full sun and is seen rarely or never in forests or brushwood.
I discovered P. bifolia ssp. bifolia at Lista completely sea in thin grassland interspersed with heather. Later I also found the completely towards sea edge in Sogn and more discoveries in Nordland in completely different habitats than P. bifolia ssp. latifolia.
