  • Discussion

    The type was determined by Prof. Greene as Senecio Fendleri, but it is very unlike the typical form of the aggregate that has been known under that name. The dark green color, the leaves which are merely toothed, never pinnatifid and still less bipinnatifid as they often are in S. Fendleri easily distinguish it from that species. The perennial caudex and rootstock are similar to that of 5. Fendleri but less thick and less woody and, as far as seen from the specimens, not branched. It grows at an altitude of about 2000 m.
