| Notes | Kelso: I think that the best way to deal with the plasticity inherent in Androsace septentrionalis is to simply call it all a single polymorphic taxon. I have found no morphological distinctions that hold up even at a population level; it is really prone to environmental responses. Seeds from alpine (also arctic) morphs that are short and few-flowered yield larger and lusher and more floriferous plants when grown in different locations. This plasticity, coupled with its probably very high level of selfing as an annual, leads to quite a lot of variation, but I am convinced that none of it is of taxonomic significance. Elven: The plasticity is further discussed by Kelso (2009a). |
