Juncus filiformis L., typical (on the left) and a morph (on the right) (Finland, Lohja, Jalassaari, 1997). – Image: Harri Harmaja (scanned from dried specimens). – The slightly deviating plants of J. filiformis (Juncaceae) grew together with typical plants in rock crevices on lakeshore. The former are distinguished by (i) lower culms, (ii) slightly yellowish green overall colouration, (iii) the presence of anthocyanin tinge especially at the bases of the largest bracts, (iv) the location of the inflorescence in seemingly halfway the plant (vs. roughly 2/3 from base), (v) the more compact inflorescence, (vi) the less long-tapering outer perianth segments, and (vii) distinct anthocyanin tint in the back of the perianth segments. These plants were rather striking in the nature but maybe they do not represent taxonomically significant variability.
