The real problem is that we still need to find the drawing and original description from Par. & Reichb.f. to know what Seidenfaded synonomizing it with. Unfortunately for fragrans/seidenfadenii vs pachyacris he does not distinguish in the key what the supposedly clear vegetative difference is (he mentions this in the comments after fragrans). Patricia do you think Ken might have this reference we need - the one listed as 1890?
