Just to introduce a weird note into the forum. I was given a large supply of old seed, and am testing it for viability. 

Picture of two nicked and soaked twenty-year-old seeds of Astragalus sobolevskiae, JJH 951081. I could find nothing at all about this species, other than it was described by Antonina Vasilevna Polozhij (1917-2003), and then collected by Halda at 2400 meters in the Altai. 

Obviously, a plant so rare, it's never even heard of itself.
