Spiranthes sylvatica, the woodland ladies' tresses or pale-green ladies'-tresses is a terrestrial orchid endemic to the United States, very similar in appearance and range to Spiranthes praecox which it had been considered a variation of for a long time.

Just like in Spiranthes praecox the lip of each flower has prominent dark green veins.

Besides the more greenish flower color another difference of Spiranthes sylvatica to Spiranthes praecox is a larger flower size, 10-17 mm as opposed to 6-9 mm.

[1][2][3][4] It grows in dry forests near the coast such as in live oak hammocks.

[2] Spiranthes sylvatica was first described as a separate species by Paul Martin Brown in 2001.
