' 1 349. S. incana, Torr. fy Gray, Fl. 2. p. 221 : var. racemis dense corymbosis ; foliis 

 plerisque acutis. — Seven miles east of Rock. Creek, a source of the Canadian ; August. 

 (525.) 



350. S. incana, verging to S. nemoralis, y. Tort: fy Gray, I. c. Santa Fe ; July. 

 (387 b.) — A well-marked dwarf state of S. incana, only a span high, with roundish 

 leaves, but less hoary than the plant of Nicollet, was collected on the Upper Arkansas in 

 Fremont's third expedition. 



351. S. lanceolata, Linn. Council Grove to the ferry of the Kansas. (529.) 

 f352. Linosyris graveolens, /3. Torr. Sf Gray, Fl. 2. p. 234. Dry, gravelly hills, 



Bent's Fort, on the Arkansas ; Sept. (341.) — " Shrub 2 to 4 feet high." — The Lino- 

 syris Texana, Torr. fy Gray, I. c, was founded on specimens which prove to be mascu- 

 line individuals of a nearly herbaceous species of Baccharis.* 



353. Aplopappus (Blepharodon) spinulosus, DC. Gravelly or sandy soil, around 

 Santa Fe, Pecos, &c. ; May to Oct. (499.) 



|354. A. spinulosus, var. glaber. Prairie on the Cimarron. (394.) — Dr. Wisli- 

 zenus gathered the same form on the Arkansas. 

 * f 355. A. spinulosus, var. canescens. Between Santa Fe and the Rio del Norte ; 



* Baccharis Texana : glabra ; caulibus plurimis herbaceis e basi suffruticosa rigidis argute striato-angu- 

 latis foliosissimis subsimplicibus apice corymboso-oligocephalis ; foliis linearibus mucronulatis vel acutalis basi 

 angustata sessilibus carinato-uninerviis marginibus obsolete repando-denticulatis ; involucri squamis lineari-lan- 

 ceolatis sensim acutis laxis ; receptaculo nudo alveolato-dentato; acheniis oblongo-fusiformibus glaberrimis 

 pappo albido involucrum duplo excedente superatis. (Linosyris Texana, Torr. 8f Gray, Fl. 2. p. 232.) — Dry 

 prairies and Post-oak woods, Texas, Drummond, Dr. Riddell, Li?idheimer, Wright ; Aug. to Nov. — Stems 

 about a foot high, in aspect not unlike Linosyris vulgaris. Leaves an inch or an inch and a half long, one or 

 two lines wide, rigid. The sterile stems or branches bear six or eight about 30-flowered heads in a leafy 

 corymb ; the limb of the corolla is deeply 5-cleft ; the branches of the style terminated by conspicuous lanceolate 

 appendages. The fertile stems bear from two to eight heads ; the corollas slender and truncate ; the soft pappus 

 half an inch long. Achenia several-ribbed. The species appears to be allied to B. thesioides, H. B. K., and 

 B. linifolia, DC. 



The Polypappus sericeus, Null, in Jour. Acad. Pliilad. (n. ser.) 1. p. 178, from Gambell's collection, is un- 

 doubtedly the same as a Willow-like silky-cinereous shrub in Fremont's, Coulter's, and, more recently, in Em- 

 ory's Californian collections, which I had ventured to refer to Tessaria. (T. borealis, Torr. 8f Gray, Fl. 

 Suppl. Compos, ined.) In habit and generic characters it well accords with T absinthioides, DC, except that 

 the receptacle is not hirsute, but naked. It is certainly excluded from Polypappus, and from the Baccharese, 

 by the caudate anthers (although the tails are short) and heterogamous heads, there being several perfect or 

 male flowers in the centre of the disk. Lieut. Emory met with it in the bed of the Rio del Norte, New Mex- 

 ico, as well as along the Gila. It is enumerated, but not described, in his Report, under the name of Tessaria 

 borealis, DC, the initials of De Candolle having been appended through some mistake.
