Pennsylvania Cudweed, Pennsylvania everlasting; Annual herb, up to 25 cm tall, slightly branched, leaves simple, spathulate, white tomentose especially on lower surface; capitula in short clusters; involucre bracts with white hairs; cypsella, pappus hairs white, Leaf surfaces of different colour, upper white hairy, lower almost glabrous; basal leaves persistent at anthesis; inflorescence spicate, lower glomerules of heads often pedunculate...............................Gamochaeta purpurea Leaf surfaces not markedly different; basal leaves withered at anthesis; heads in spicate panicles, densely wooly 2/3 from base....................................................................................Gamochaeta pensylvanica It is true that the three species are very close, Gnaphalium purpureum, G. pensylvanica are shifted to genus Gamochaeta on the basis of pappus being connate at the base, whereas in Gnaphalium they are free at base and fall individually This is what Flora of China writes about Gnaphalium polycaulon "Similar to Gamochaeta pensylvanica, this species differs by its more compact habit, oblanceolate leaves, and free, separately deciduous pappus bristles more dilated at apex." Herbs, erect, upto 50 cm high; stem, with thin, white cottony tomentum. Leaves spathulate, narrowed at base, broadly rounded and shortly mucronate at apex, entire, 1-7 x 0.1-1 cm, puberulous on upper surface, white pannose on lower surface. Heads in short spicate clusters, ca 2 mm across; peduncle ca 1 mm long. Involucral bracts 3-4-seriate; outermost brown, occasionally pink at apex, oblong-spathulate, obtuse-acute, with white woolly tomentum at base. Ray florets female, with filiform corolla, ca 1 mm long, pink at mouth. Disc florets bisexual, ca 2 mm long, 5-toothed. Achenes oblong, ca 0.5 mm. Pappus hairs white, united at base.
