Hi @frankiecoburn. Please forgive me, as I do not remember every detail since some time has passed since then, but CalFlora is cited here as the reference for the atlas for these taxa due to lack of better material and the range Kew recognizes for M. comata on its assessment page matches CalFlora. Our plant authority Plants of the World Online (POWO) recognizes this swap.
I worked with professional botanists in the southwest and they have told me that Mirabilis comata is a true species separate from M. albida. This is reflected in the 2020 edition of Flora Neomexicana. Some discrepancies exist where Flora Neomexicana suggests both M. comata and M. albida are in New Mexico, so that may be the case for other states as well, but I am not sure how these species are well differentiated. Every observation I have personally made of this complex has been identified by others as Mirabilis comata.
Maybe @aspidoscelis or @normdouglas would have greater insight on this issue.
Hey @frankiecoburn & @bobby23, my understanding of this is that Rich Spellenberg reversed himself on M. comata in Intermountain Flora as a southwestern form of M. albida. Plants like the one Bobby found fit this concept, which is fairly distinctive in the field. While eastern M. albida is pretty uniform, the SW variability remains unsatisfactorily partitioned into stable taxa. Personally, I think this one is like some of the other segregates of the broad M. albida complex that have been named and reside in various states of nomenclatural obscurity (e.g. "Allionia pratensis").
[EDIT] I haven't done a deep dive into the species descriptions, but my impression based on the EOL synonomy in the iNat species page indicates that it's using an older concept of M. comata by Billie Turner (1993) that Spellenberg rejected when he re-established the plants that Billie was calling M. comata as M. melanotricha. The EOL data says M. melanotricha (under old genera) is a synonym of comata and that's not the case for us here. Also, Spellenberg has M. comata going farther west through SW UT all the way to Inyo Co. CA and Mineral Co. NV, in addition to AZ, NM, W. TX, and northern Mexico.
If you want to send me your email addresses I can fwd the galley copy of Intermountain Flora I have where Rich comments on this species. My email is n a d o u g l a s @ u f l . e d u ( no spaces). Obviously you could contact Rich as well.
I've had a few conversations with Rich in which he expressed his misgivings about having adopted such a broad circumscription of Mirabilis albida in the Flora of North America. Seeing the northern NM observations of Mirabilis comata trickle in this year has also supported the idea that this is a distinct species in my mind, though I do not know Mirabilis nearly as well as Norm, nor Rich of course!
Hi @bobby23 , I am curious how this taxon swap was decided. Cal flora was the main reference? It appears the name is inactive on their site. Were there any others? ITIS and Flora of North America did not recognize this taxon.
I think one issue that may have me confused is the name M. comata has replaced the name M. albida in many southwestern US observations due to the taxon split. In many of these situations, I don’t think it’s resolved they are not M. albida.
Thanks for any helpful info. Trying to better understand this group in the southwest US.
