Newly reported species and infraspecific taxa from our region in volumes of Flora of North 

 America generally have been included, but they were incorporated to minimize changes needed 

 at the generic level compared to Snow07b, given the ongoing scoring of characters for taxa in the 

 Southern Rocky Mountain Interactive Flora (Brasher06). In a few cases where species 

 boundaries remain tentative in our region (e.g., Eleocharis, Cirsium, Grindelia) 1 have not 

 hesitated to indicate that a doctoral dissertation for that group is needed. Taxa collected only 

 once or twice long ago are in some cases treated as waifs that were subsequently extirpated (e.g. 

 Claytonia umbellata). However, in cases where non-native taxa frequently are planted 

 ornamentally (e.g., Linum usitatissimum) and are likely to escape at least occasionally in 

 localized areas, the taxa have been included as "present". 



It is unfortunate that the larger herbaria of our region (COLO, RM, CS, UNM, COCO, GREE, 

 Kill)) arc so unaligned nomenclaturally. Curators and collections managers in the SRMR 

 should consider whether adoption of the nomenclature presented here (with modifications as 

 necessary) more broadly. The National Science Foundation will support workshops and 

 collaborative initiatives that work towards regional cooperation and standardization. The SRMR 

 lags behind parts of the USA (e.g., southeastern US, California, lntermountain Region, Great 

 Plains), where curators work collaboratively at documenting and disseminating data 

 electronically about their regional flora (e.g., see httnj//w\vvv.sernec.org/flles/R.A.O.Dec- 

 2008.pdf ). 



"Version 3" reflects six years of updates. While some will groan at changes, it is a good thing 

 that systematics is a vigorous science and enhancing our understandings of species boundaries 

 and evolutionary relationships (and thus generic boundaries). The next version of the Checklist 

 will indicate state-wide distributions for each taxon (WY, CO, NM).
