SIMILAR SPECIES: This species is very similar to the common G. obtusifolium. The leaves of G. viscosum are partly clasping and decurrent as wings down the stem and the entire plant is glandular-hairy or wooly. The leaves of G. obtusifolium are sessile, but not decurrent, and the plant lacks the glandular hairs.

TOTAL RANGE: Que. to B.C., s. to WV, TN and Mex.

STATE RANGE: This species was last collected in Ohio in 1926. There are historical records for Columbiana, Cuyahoga, Mahoning and Trumbull Counties.

STATE STATUS: 1980 to present: Presumed Extirpated.

HABITAT: Moist open situations, often in sandy soil; open woods, clearings, pastures, fields.

HAZARDS: Overshading by woody species as a result of succession; mowing, grazing.

RECOVERY POTENTIAL: Presumed good due to its variety of habitats and apparent tolerance of disturbance.

INVENTORY GUIDELINES: Collect complete, mature flowering or fruiting specimens.

COMMENTS: This taxon is referred to as Gnaphalium macounii in much of the botanical literature, including Fernald (1950) and Gleason and Cronquist (1991), though not in Fisher (1988). The species should be sought in disturbed or open sites throughout northern Ohio.
