Quinn and Sterling (2006), in the reference that I supplied on 27 July 2011, state that Romneya coulteri is "not restricted to the postfire chaparral but can be found in burned areas of southern California." Standard floras, however, including the Jepson Manual, the Flora of North America, and Munz's Flora of Southern California, explicitly mention the well known fire-following nature of Dendromecon rigida but are silent on this matter with regard to the two Romneya species. Experience (unreferenced!) suggests that the two Romneya species persist for the long-term in areas that have not burned for many years, whereas D. rigida declines in abundance with increasing time from the fire, as is common with fire followers. Any more definitive information on the fire-following nature, or not, of Romneya would be welcome. WMThomas ( talk) 00:14, 28 July 2011 (UTC) reply

Currently, the article on the genus Romneya lists two included species (R. coulteri and R. trichocalyx) and appears to link to separate articles for each, but both links go to Romneya coulteri, which characterizes the two species names as synonyms. This contradiction is confusing, exacerbated by the separation of the conflicting information. Maybe until material exists at WP substantiating that the other species name (R. trichocalyx) identifies a different species, the simplest thing would be to merge the articles, which would be consistent with practice for monotypic genera.

The Jepson Manual currently recognizes two species, so there needs to be an article for R. trichocalyx.-- Curtis Clark ( talk) 02:33, 24 April 2012 (UTC) reply

Okay, I've created Romneya trichocalyx.-- Curtis Clark ( talk) 02:59, 24 April 2012 (UTC) reply

This article states that romneya produces the largest flowers of the entire poppy family, but I do not believe that this is true. The are giganteum varieties of P. Somniferum which can easily have blooms to 8in. and possibly larger. I would like to see a reference for this because the size indicated in the article is smaller. Cheers and thanks!
