Pseudognaphalium viscosum

Pseudognaphalium viscosum (synonym Gnaphalium viscosum), one of the Mexican cudweeds known as gordolobo, is an aromatic annual or short-lived perennial herb in the family Asteraceae. It grows erect to about 30 to 80 centimetres tall, the stems and foliage covered in a sticky, glandular-viscid pubescence that gives the plant its name. The alternate leaves are narrowly lanceolate to linear, sessile and somewhat clasping, green and glandular above and often paler beneath. The small flower heads are grouped in dense terminal corymbose clusters, each head cylindrical with golden to straw-coloured, papery (scarious) involucral bracts surrounding numerous tiny yellowish disc and thread-like female florets. The fruit is a minute achene bearing a pappus of fine bristles. The species is widespread through the highlands of Mexico and Central America, growing in disturbed ground, roadsides, pine-oak woodland and open slopes.
