feeble dwarf 3' high, in absolutely sterile soil, to 6-8° high in 
productive soil. It is an erect-growing, wand-like, weedy- 
looking annual; leaves linear, mostly entire, the radical 
cut-lobed, heads very numerous and small, cylindrical, pan- 
icled. Rays inconspicuous, in several rows, scarcely longer 
than the pappus; pappus simple. Ligule of the ray-flower 
shorter than the tube ; white. It has spread over the whole 
world and grows in all kinds of soil, on old walls, etc. The 
leaves and tops of this species are collected before flower- 
ing, to be subject to distillation, by which an e-sential oil 
passes over. Oleum Erigerontis.

weed, in pastures and waysides, stems 3-5° high, branched, 
beset with spreading hairs; leaves coarsely and sharply- 
toothed ; the lowest ovate, tapering into a margined petiole,
