Odd plant in a seep

This was growing in a saline barrens. It was in a seep, in about 5 inches of water. It was 2 feet tall, with alternate leaves. The leaves were lanceolate, sessile, with a strong central vein and 2 weak, parallel veins. Both leaf surfaces were densely covered with glandular spots. Both surfaces also had appressed, scale-like hairs that seemed flattened. Blades were 4 cm long by 6 mm wide with about 4 short teeth on each side, in the distal 1/3. Stems were densely strigose above, and glabrous below. Inflorescences were about 1.5 inches high, of flat-topped cymes with outer peduncles about 2 cm long. Pedicels were about 0.5 mm long. The largest florets were 4 mm long by 1.5 mm
wide. They had six bracts (of 3 different lengths) that were often red-tipped. Inside that was a closed structure that seemed to have 4 petals (?) that were 3.5 mm long by 1 mm wide. Inside that were 4+ barrel-like structures with several long, segmented, flattened bristles from their base. The inflorescence was also densely strigose. I didn’t see any evidence that the flowers would open, or do anything other than what is shown in the photos. Any idea of the species? There wasn't any smell, and although the 1st photo looks a bit like Pluchea, it isn't.
