STUDIES IN THE COMPOSITAE. 267 
A rather rare species of southwestern Texas and adjacent 
New Mexico. The great bulk of the material in our herbaria 
named Actinella scaposa is of the next species. 
8. T. LINEARIS. Actinella scaposa var. linearis, Nutt. Trans. 
Am. Phil. Soc. vii, 379 (1841). Ceespitose but the short caudex 
slender: leaves very narrow and almost linear, pubescent 
but not villous, the punctuation manifest, but superficial 
rather than impressed: scapes tall and slender: pales of 
the pappus obovate, obtuse, tipped with a rather long awn. 
The most common species of the Texano-New-Mexican 
region, and, as I have before intimated, plentiful in the 
herbaria under the name of Actinella scaposa. 
9. T. AUGUsTATA. Apparently not cæspitose, the stems soli- 
tary or several from slender and deep-seated perennial roots: 
leaves elongated and narrowly spatulate-linear, sparsely vil- 
lous-pubescent and impressed-punctate, the scarious margins 
of the petiolar base serrulate-scabrous or somewhat ciliate : 
Scapes very slender, a foot high; involucre somewhat silky- 
tomentose, the bracts unequal, obtuse: paleæ of the pappus 
obovate, deeply notched, a short awn proceeding from the 
notch. 
Obtained in the State of Chihuahua, Mexico, in 1886 (n. 953), 
in the month of November, in full flower at the time; there- 
fore an autumnal species, all the others being vernal. 
10. T. rRINERVATA. Branching eaudex stout and low, 
densely leafy : leaves firm, spatulate-linear, acute, sparingly 
and rather superficially punctate under a dense short silvery 
appressed pubescence, the petiolar base coriaceous, entire, 
glabrous except at the villous insertion, strongly 3-nerved : 
scapes 2 or 3 inches high, little exceeding the leaves: bracts 
of the involucre somewhat tapering upward from the middle,
