Heads up: Some or all of the identifications affected by this split may have been replaced with identifications of Spiranthes. This happens when we can't automatically assign an identification to one of the output taxa. Review identifications of Spiranthes stellata 416163

Taxonomic Split 92727 (Committed on 2021-05-31)

First published in 'The evolutionary and systematic significance of hybridization between taxa of Spiranthes (Orchidaceae) in the California Sierra Nevada and Cascade Range', these changes are now also accepted by POWO.

@afid, @matthewpace, @neontetraploid, @catullus, I feel like the time has come to implement these new taxa. If you have any comments or concerns, please let me know.

Seems good to me!

Looks good!

I'm going to be very busy with finals this week but hopefully next week I can help with any observations that need to be corrected.

No worries. According to the Pace and Cameron, S. perexilis has a gracile inflorescence (rather than robust) with a lax spiral (rather than tight). The dilated apex of the lip is 1.3-1.6 mm wide, in contrast to S. × stellata, which has apices that are 1.7-2.8 mm wide. I'm going ahead with the split now, so any help (if time permits) would be appreciated.

Cheers!

Thanks! Just wondering, why are you tentative about your S. perexilis identifications? Those observed plants seem to have very lax spirals and slender labella, right? I've agreed to your identifications but checked "yes" for "needs further confirmation" to make sure they stay Needs ID.

I'm not familiar with that species yet, so I try to play it safe until we can get Matthew Pace to review some. I need more experience before I can be sure what the morphological expressions of the two species are, and where overlap may exist.

Ah I see, thanks!
