There is no clear distinction between a "geophyte" and other perennials. Dodecatheon clevelandii, with a small slender taproot, functions just like a bulb in cultivation. The same can be said for various umbellifers, composites, mallows and others. Some prefer a broader interpretation of "geophyte", others a more narrow circumscription. A "non-traditional" entry in the wiki should have some explanatory text that justifies marginal qualification, or perhaps be relegated to a separate category of nominal geophytes. This could help provide nuance where there is no settled classification or real distinction. Dylan * *
