The next time I see a liverwort I must look closer... tiny plants in the cups, huh.
A little story... back in the early 70s my husband had a task of finding some liverworts for a botany project in college. We drove all over the place on dirt roads, in the woods etc up in Washington. We went days looking for this critter and time was getting short! We did finally find some, don't recall just where though. But in retrospect if I knew then what I know now we could have just gone to a nursery that had somewhat old stock in gallon containers as that is where I find liverworts now!
