Platanthera pallida, commonly known as pale fringed orchid,[1] is a rare orchid of North America with the only known occurrences on Long Island.
Description
[edit]Platanthera pallida plants are terrestrial orchids that look similar to Platanthera cristata - in fact before recognition as a species they were suspected to be variations or hybrids.[2] They are 29-65 cm tall and have 2-3 lower leaves which are up to 25 cm long, as well as several reduced upper leaves. There are 24-80 flowers arranged in a raceme at the top of the stem, with a pale orange-yellow to pale cream color and a short nectar spur. Bloom time is in summer.
Distribution and habitat
[edit]Platanthera pallida is endemic to Long Island in New York with only three known populations. It grows in dry areas between sand dunes.[2]
Taxonomy
[edit]Platanthera pallida was first described as a new species by P. M. Brown in 1992, when he examined plant populations that had been suspected to be variations or hybrids of Platanthera cristata.[2] The USDA's plants database considers them identical to Platanthera × canbyi (the hybrid of Platanthera cristata with Platanthera blephariglottis).[3] Future studies are likely to re-examine the current status as a separate species.[4]
