Spiranthes bightensis, the Atlantic ladies tresses, is a terrestrial orchid native to coasts of the north-eastern United States. [1] [2]
Spiranthes bightensis plants look similar to Spiranthes cernua and Spiranthes odorata . They are tall (up to 100 cm), with 1-5 basal leaves present at flowering time, and wider than those of Spiranthes cernua. The white flowers are arranged in a spiral around the stem. Spiranthes bightensis flowers are usually fragrant, while Spiranthes cernua ones are not. [1]
Spiranthes bightensis is endemic to the eastern US Mid-Atlantic shoreline and the New York Bight. The species name bightensis derives from this bight. It occurs in Delaware, Maryland, New Jersey, New York and Virginia. [2]
It prefers wet to moist meadows, coastal dune swales and sphagnum areas around water edges. [1]
The southernmost edge of the range of Spiranthes bightensis is north of the range of Spiranthes odorata and the two ranges do not overlap. The range of Spiranthes bightensis does overlap that of Spiranthes cernua however plants do not normally co-occur at the same location. [1]
A small population have turned up in Belgium, it is presumed they have escaped from cultivation.
Spiranthes bightensis is believed to be an ancient hybrid between Spiranthes cernua and Spiranthes odorata. M. C. Pace first described and published the plants in 2021. C. F. Austin collected several specimens in the 1800s and labelled them S. cernua var. gigantea but never published that name and later botanists who collected the plants usually labelled them as S. cernua. [1]
The Chadds Ford spiranthes cultivar, often sold as "Spiranthes cernua 'Chadds Ford'" or "Spiranthes cernua var. odorata 'Chadds Ford'" which had long been identified as belonging to Spiranthes cernua or Spiranthes odorata is actually neither of those and instead a cultivated version of Spiranthes bightensis. [1]
Hepatica is a genus of herbaceous perennials in the buttercup family, native to central and northern Europe, Asia and eastern North America. Some botanists include Hepatica within a wider interpretation of Anemone.
Zantedeschia is a genus of eight species of herbaceous, perennial, flowering plants in the family Araceae, native to southern Africa from South Africa north to Malawi. The genus has been introduced on all continents except Antarctica. Common names include arum lily for Z. aethiopica and calla and calla lily for Z. elliottiana and Z. rehmannii, although members of the genus are neither true lilies of Liliaceae, true Arums, nor true Callas. The colourful flowers and leaves of both species and cultivars are greatly valued and commonly grown as ornamental plants.
Spiranthes is a genus of orchids in the subfamily Orchidoideae. They are known commonly as ladies tresses, ladies'-tresses, or lady's tresses. The genus is distributed in the Americas, Eurasia, and Australia. The genus name Spiranthes is derived from the Greek speira ("coil") and anthos ("flower"), and was inspired by the spirally arranged inflorescence.
A bulbil is a small, young plant that is reproduced vegetatively from axillary buds on the parent plant's stem or in place of a flower on an inflorescence. These young plants are clones of the parent plant that produced them—they have identical genetic material. The formation of bulbils is a form of asexual reproduction, as they can eventually go on to form new stand-alone plants.
Ulmus bergmanniana var. lasiophyllaC. K. Schneid. is endemic to China, on mountain slopes at elevations of 2100–2900 m in Gansu, Shaanxi, north-west Sichuan, south-east Xizang, and north-west Yunnan.
Spiranthes romanzoffiana, commonly known as hooded lady's tresses or Irish lady's-tresses, is a species of orchid. Collected by Chamisso during the Romanzov expedition it was described by him in 1828 and named for Count Nikolay Rumyantsev who financed the expedition. This orchid is native to North America, Ireland and the British Isles.
Spiranthes cernua, commonly called nodding lady's tresses, or nodding ladies' tresses, is a species of orchid occurring from Maritime Canada to the eastern and southern United States. As the common name suggests cernua means "nodding", or "bowed" in Latin.

Butia odorata, also known as the South American jelly palm, jelly palm, or pindo palm, is a Butia palm native to southernmost Brazil and Uruguay. This slow-growing palm grows up to 10m, although it is often less tall. It is identifiable by its feather palm pinnate leaves that arch inwards towards a thick stout trunk.
Spiranthes incurva, the Sphinx ladies' tresses, is a species of flowering plant in the family Orchidaceae. This orchid is native to the upper Midwest and Great Lakes Basin of North America. The species was originally described as Ibidium incurvumJenn. in 1906.

Spiranthes incurva is an ancient natural hybrid of S. cernuasensu stricto and S. magnicamporum.
Spiranthes arcisepala, the Appalachian ladies' tresses, is a species of flowering plant in the family Orchidaceae. This orchid is native to eastern North America.
