2. Pseudognaphalium micradenium (Weath.) G.L. Nesom (rabbit tobacco)

Gnaphalium obtusifolium var. micradenium Weath.

G. helleri var. micradenium (Weath.) Mahler

P. helleri var. micradenium (Weath.) Kartesz

Map 1139

Plants usually strongly aromatic when bruised or crushed. Stems 25–75 cm long, sometimes somewhat woolly when young, but not appearing woolly below the inflorescence at maturity, instead moderately to densely glandular, the minute, stalked glands 0.1–0.2 mm long. Leaves 1–9 cm long, linear to narrowly lanceolate or narrowly oblong-lanceolate, the upper surface with moderate to dense, minute, stalked glands. August–October.

Uncommon, known thus far only from Shannon and Ste. Genevieve Counties (eastern U.S. west to Minnesota and Louisiana). Savannas and openings of dry upland forests.

Steyermark (1963) noted that this taxon occurs in acidic soils on rocky slopes and ridgetops. Some authors have treated it as a variety of Gnaphalium obtusifolium (Steyermark, 1963) or the closely related G. helleri (Mahler, 1975). The present treatment follows that of Nesom (2001), who noted that the ranges of P. helleri and P. micradenium are largely distinct and that hybrids appear to be absent from the zone of overlap between the two.
