268 PITTONIA. 
11. T. FAsTIGIATA. Subligneous stem 6 or 8 inches high, 
parted into many fastigiate densely leafy branches and form- 
ing a compact tufted undershrub-like plant: leaves spatu- 
late-linear, acute, glabrous or somewhat scabrous, super- 
ficially punctate, the basal part much dilated, with strong 
midvein and no lateral nerves, the margin hirsute with long 
deflexed hairs: scapes slender, shorter than the leafy branches 
but 3 to 5inches long: involucre narrow and small, its bracts 
oblong, obtuse, pubescent. 
Inhabiting dry hills, Coolidge County, Kansas, collected 
by B. B. Smyth, 22 Aug., 1890; the plant then long past 
flowering. The only specimen seen is in the herbarium of 
Columbia College. 
12. T. GLABRA. Actinella glabra, Nutt. Trans. Am. Phil. 
Soc. vii. 379 (1841). Near of kin to T. acaulis and T. Tor- 
reyana, more herbaceous than either, nearly glabrous, leaves 
much less punctate, and the involucral bracts not scarious- 
edged. 
Good specimens of this species, which is of the Rocky 
Mountain plains rather than of the foothills, or mountains, 
were obtained by Hall and Harbour, and also in 1868 by 
Geo. Vasey. But it has seldom been collected, and is rare 1n 
herbaria. 
13. T. HERBACEA. Much larger than the last, wholly 
herbaceous even to the branched crown of the root, theleaves 
slightly fleshy or subcoriaceous, oblanceolate and linear-lan- 
ceolate, impressed-punctate, but the dots small, appearing 
glabrous, but sparsely villous-pubescent under a lens: stout 
scape villous-tomentose at summit; bracts of the involucre 
subequal, oblong, very obtuse, the inner ones with narrow 
and erose scarious margins: rays with obvious traces 
partly disconnected veins between the four usual ones and 
accessory to them : oblong-ovate pales of the pappus obtuse 
or acute, some apiculate.
