Hello, David.

I think the focus on the Vaginatae (which is several decades old) will last the rest of my working life. A huge, huge job.

There is still much work to do on other sections; however, collecting of citrinoid taxa (except for very unusual geographic locations) is pretty much over as far as the “lavendula group” goes. Now the lab work and writing will absorb a great deal of effort.

Likewise with the rubescent taxa (except for uncovered geographic areas).

We will continue to look at material across all sections; however, the biggest problem with the sheer number of unnamed taxa is probably in the Vaginatae…worldwide.

We are continuing sequencing of as many types as possible with sequencing of as much of the Roosevelt herbarium as possible in order to establish a genes-to-names mapping for accepted and provisional names and progress toward publication of the heretofor provisional names. We are building up some very good sets of data (populiphila, for example).

Thanks for keeping an eye out for the rhacopus-like taxa. I know the group as a whole is very common. As I’ve noted somewhere on MO already today, two taxa account for about two-thirds of the sampled collections. Knowledge of all the taxa (even the most common ones) needs to be improved. We need macroscopic and microscopic morphological data especially…in quantity.

Very best,


I think I may have submitted…

a few PA rhacopus types a year or two back. I’ll try to get some new material for you, Rod. I believe your emphasis this year is on section Vaginatae…?

Of the entities in the “rhacopus group,” we have not gotten Pennsylvanian DNA

from either of what appear to be the most commonly collected species (rhacopus in my current understand and sp-T01). So I would be interested in any “rhacopus group” material from your neck of the woods, David.

Very best,


I think A. “sp-T01” is another alternative…

because of the dingy coloring.
