Steve Matson: Mono County, Bodie Hills. Rare Plant rank 2B.2. Here is a plant that I am sure most of you have never heard nor ever seen: Lupinus uncialis, "lilliput lupine", or "inch high lupine". Previously known in California from just Modoc County, but recently discovered by Ann Howald and Tim Messick in Mono County. It is more widespread in Nevada. Earliest herbarium collection is by Sereno Watson from 1871 in western Nevada. You can actually see this plant while standing up, but it is still only about 2cm tall. This must be (one of) the smallest lupines in the world! I saw it in fruit in central Nevada a few years back, I had no idea what I was looking at at the time, a little leafy fuzzball with a tiny "pea" pod attached. It took thumbing through the Fabaceae Volume of Intermountain Flora to find it. (contributed by Cynthia Powell)
