…your comment that 113909 stands a good chance of being sequenced eventually. :-)
The umbo/knob looks quite prominent to my eyes, but it’s a relative assessment with no reference point. Sometimes color contrast makes all the difference. Here there is practically no color gradient and the flash is on in some pix, so the umbo may look smaller. On the other hand, lots of color contrast may increase the emphasis to a certain structure.

On the other hand, the umbo is not so prominent.

We have never sampled this material. We are in the process of going back in time in the herbarium looking for collections of Vaginatae that have not been sequenced. There are a lot, I think. We recently sequenced some old collections of Sam Ristich’s from Maine and found many of them were new taxa. My next project is to stalk going backwards through the herbarium collections that do not have the word “sample” or “sampled” on the label. Its going to make our backlog truly amazing. I will begin to eliminate some species from sequencing to try to keep the size of my “problem” down, while leaving me a good chance of continuing to find new taxa associated with notes and photographs.

Very best,


Yes, Igor. This could be a fresh specimen of MO 108462. I see your point.
