Description
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.
Distribution and habitat
Taxonomy
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.{{cite journal |last1=Pace |first1=Matthew C. |title=The Orchidaceae of northeastern North America |journal=Memoirs of the Torrey Botanical Society |date=2020 |volume=29 |pages=156–189 |publisher=Torrey Botanical Society}}
