This material has been received and accessioned to Rod’s herbarium.

I’ll set it aside for you Dr. T and…

Hello, Jon.

I’d love to have the material.

We have a long way to go in defining the morphological characters that go with the different sequences or groups of sequences that we think define the rubescent species in eastern North America. Dr. Hughes had set aside a period of time to dedicate to the gathering of samples and sequencing of data. Unless something unforeseen happens, any additional sequencing at this point will probably not happen in Knoxville. There is a lot of other work to do; so the final output is probably over a year away on the citrinoid taxa and even farther off for the rubescent taxa.

So I can’t say that I know we will sequence your specimen. However, it is a specimen that is nicely documented in your photographs.

If you check out species in sect. Caesareae on the WAO site, you will see that there are a lot of new DNA sequences posted for some of them. This is an indicator that Santiago Sanchez it getting close to publishing his first paper on that group.

I think that we (folks in New Jersey) are getting close to starting to put more sequences for the Vaginatae on-line including some sequences based on type and other original material.

Very best,

Do you want this Dr. T? Or, are you moving on to A. vaginata now?

Nice clear images.

This is one of the taxa that I lumped together (by mistake) a “amerirubescens”. There are a lot of similar taxa that, at the moment, can only be separated by gene sequences.
