ARTEM ISIA FLOCCOSA.
Stem stout, 5-7 dm. high, striate, tomentose; leaves pinnately divided into oblong segments, loosely white-tomentose on both sides ; heads 5-6 mm. in diameter, erect, evidently pedicelled, in an elongated narrow raceme or panicle; bracts oval, scarious margined and tomentose.
It is nearly related to the preceding, differing mainly in the looser tomentum, and the erect pedicelled slightly smaller heads.
From A. Tilesii elation it differs in the tomentum, the form of the leaves, and the erect heads with tomentose bracts.
Type: P. A. Rydberg, no. 2942, Lima, Aug. 6,1895.
