In Drepanocladus mats with Senecio congestus, Stellaria crassifolia in wet marly soil at edge of lakes. Edge of upper zone of lake in deep humus. Stem compressed atypical. Achene pale light green, perianth bristles 5-6 exceeding tubercle, achene apex without distinct neck. Eleocharis mamillata ssp. mamillata according to FNA but very close to E.palustris. Indeed one spikelet had mature fruits, most of the perianth bristles are slightly longer than the achene and tubercle. None of the 8 or so achenes had more than 4 perianth bristles, 4 being at the low end of variation in this species, but still fit. J. Saarela Jan. 2008. Common. 3 duplicates (CAN).
