AsTKR (Macit^ranthera) Pattersoni. E radice bienni seu 

 vix pereimi multicaulis, subspithamajus ; foliis spatliulatis integerrimis 

 (radicalibus nunc apicem rotuiidatum versus leviter pauci-dentatis) la;te 

 viridibus piloso-ciliaiis demum glabratis ; cauHbus supenie glanduloso- 

 pnbesceutibus 2-4-foliatis 1-4-cephalis ; invplucri hemisphosrici squamis 

 3-4-serialibus fere Eeqnilongis lanceolatis acuminatis ultra medium herba- 

 ceis et squarroso-patentibus pube viscosa soepius hirtella crebre indutis; 

 ligulis numerosis semipollicaribus loJte coeruleo-viohxceis ; acheniis ut 

 videtur linearibus glabriusculis. — Colorado Rocky Mountains, at about 

 11,000 feet and higher along the branch of Clear Creek flowing from 

 Torrey and Gray's Peaks, Dr. Parry, 1872; H. N. Patterson (in 

 honor of whom tlie species is named), 1876; J. D. Hooker and A. 

 Gray, 1877. A liandsome and large-flowered dwarf species, with 

 heads larger than those of A. Coloradoensis, and much larger than those 

 of the related A. Kinffii, of D. C. Eaton (which has been collected in 

 a larger form farther south in tlie Wahsatch by Dr. Parry) : including 

 the rays, it has a diameter fully an inch and a half. Tl)e stems in Mr. 

 Patterson's specimens are fully a span high. — Var. ? IIalhi, gracilior, 

 magis ramosus ; foliis raraealibus linearibus ; capitulis minoribus ; 

 involucri minus pubentis squamis fere subulatis. This is mixed with A. 

 {xUachceranthera) tanacetifoUus in the distribution of Hall and Har- 

 bour's Colorado Collection, no. 285. and indeed the heads of this form 

 closely resemble those of that species. We found a little of it on 

 La Veta or Sangre de Cristo Pass, S. Colorado.

 pedunculis brevibus ; capitulis parvis (lin. 3" longis) ; involucri squamis 

 subulatis inasqualibus ; ligulis uuUis ; acheniis hirsutis (bicostatis) ; 

 pappo exteriore setuloso sat manifesto. — Sierra Nevada, California, in 

 crevices of rocks at Donner Lake, E. L. Greene, October, 1874; and 

 above, on or near the summit of Mt. Stanford, J. G. Lemmon, A.

 L. rupestri similior, ultraspithamaea e basi lignosa crassa ramosa, cine-
