David Pilling wrote me privately on Jan 14 before posting Sarah Bettany's query 
about Cosmos atrosanguineus to the mailing list on Jan 28.

The primary issue is the source of the information that wild collected seeds 
were sent to the Rancho Santa Ana Botanic Garden.

I've looked through my email archive at some length and checked for any aides 
de memoire I may have made, but regrettably I did not record where I found that 
information. It may be that in my memory I confused the Santa Ana garden with 
the Huntington Gardens.

The two likeliest candidates as sources of this possibly-garbled information 
are (a) Google searches on "Cosmos atrosanguineus" and (b) discussion on the 
forums of the Scottish Rock Garden Club. For the Google searches, it will be 
necessary to dig far beyond the first page of results if anyone wishes to track 
this down.

I have a clear recollection of unearthing reports of finding this elusive plant 
in at least four different sites in Mexico and locating these sites at the 
Google map of Mexico.

I *did* record these four sites in a memoir; they are

San Luis Potosi (extinct, but being re-introduced)	
Zimapan, Hidalgo (type)

In 2006, Fred Boutin reported on finding this growing in Jalisco:

I could tear my hair out over not being able to substantiate the remarks I've 
made on the PBS list about this. That'll teach me not to bookmark such things!
