eighty years ago, that Valdemar Knudsen discovered such spectacular examples as Diellia Mannii, D. centifolia, and many, still mysterious varieties. Although I have spent many weeks hiking along the scenic trails through these many valleys, I was not lucky enough to run onto the particular slopes where these ferns grow. This is an event which is being saved for some fortunate botanist-in the course of his professional studies, or merely while on vacation. Hunting Diellia will probably remind that botanist of studying the rare spleenworts, and the habitat is very similar. Only when the particular hillsides that Knudsen alone knew of are rediscovered will the still unsolved problems of Diellia be clarified. |
