Platanthera shriveri, Shriver's purple fringed orchid [1] , is a rare orchid endemic to the United States. It is considered critically imperiled. [2]
Platanthera shriveri plants look very similar to Platanthera grandiflora and a hybrid origin with Platanthera lacera is suspected. To distinguish Platanthera shriveri from Platanthera grandiflora small morphological details and a different bloom time (July and August, about 3 weeks later) have to be observed. [1]
The only known populations are in Maryland, North Carolina, Pennsylvania (historic record only), Virginia and West Virginia. [2] They grow in woodlands and along stream banks.
Platanthera shriveri was described as a new species by P. M. Brown in 2008.
There is ongoing research whether the plants described as Platanthera shriveri are a separate botanical species or can be considered within the morphological and bloom time ranges of Platanthera grandiflora. [3]

Elizabeth Gertrude Britton was an American botanist, bryologist, and educator. She and her husband, Nathaniel Lord Britton played a significant role in the fundraising and creation of the New York Botanical Garden. She was a co-founder of the predecessor to the American Bryological and Lichenological Society. She was an activist for protection of wildflowers, inspiring local chapter activities and the passage of legislation. Elizabeth Britton made major contributions to the literature of mosses, publishing 170 papers in that field.
