PLANTH FENDLERIANZE. 75 
7549. S. mncana, Torr. § 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. Torr. § Gray, l. c. Santa Fé; 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. tanceotata, Linn. Coduc Grove to the ferry of the Kansas, (529.) 
+352. Linosyris craveotens, 8. Torr. & 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. & Gray, |. c., was fotinded 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 Fé, Pecos, &c.; May to Oct. (499.) 
7 354, A, SPINULOSUS, var. GLABER. Prairie on the Cimarron. (394.) — Dr. Wisli- 
zenus gathered the same form on the Arkansas. 
1 355, A. SPINULOSUS, vat. CANESCENS. Between Santa Fé and the Rio del Norte ; 
* Baccuaris TexaNa: glabra; caulibus plurimis herbaceis e basi suffruticosa rigidis argute striato-angu- 
iatis foliosissimis subsimplicibus apice corymboso-oligocephalis ; foliis linearibus mucronulatis vel acutatis 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. §- Gray, Fl. 2. p. 232.) — Dry 
' prairies and Post-oak woods, Texas, Drummond, Dr. Riddell, Lindheimer, Wright ; Aug. to Noy. — 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, Nutt. in Jour. Acad. Philad. (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. § 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 Baccharez, 
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- 
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.
