Llatris tenuicaulis sp« nov. 
Liatris tenuicaulis sp» nov. Plant perennial from a relatively small 
thickened, globose, or broader than long corm, which is up to 3 cm, in diameter 
on old plants bearing 4 or more stems, but for most plants is about E cm, in 
diameter, the smaller corms bearing only 1 stem; the stems are direct from the 
com or are branched IJust above it or as much as from 1-2 cm, above the com, 
in either case the base of the stem is densely sheathed with the erect fibrous 
remains of earlier basal leaves and all are simple, slender, striate, S mm, or 
less in diameter, frequently exceeding a meter in height (one measuring HE cm,), 
puberulous, and prominently leafy at the base; the leaves are glabrate, epunctate, 
and narrowly linear, E mm, or less wide, the basal being 15-20 cm, long, gradually 
becoming smaller above, and on above the lower third of the longer stems the 
narrow leaves are closely appressed to the stem and eu*e not noticeable as such 
thereby accentuating its slenderness; the heads are arranged in a long, slender, 
spike-like raceme, which is as much as 45 cm, long and about 2 cm, broad, are 
commonly 3-flowered; peduncles short and smooth; bracts subulate, shorter than 
the flowers, except in the lowermost heads; involucres turbinate, 7-8 mm, high, 
3-3,5 nia, broad at the top, of relatively few bracts in several series, the lower¬ 
most extending well down on the peduncle and about 1 mm, long, with each inner one 
progressively longer, the innermost about 7 mm, long, all bracts are puberulous, 
acute or acuminate, ciliate, while the Innermost ones are narrowly scarious-margined, 
and 5-7 nerved, but not prominently so; achenes 4,5 mm, long or less, tapering from 
a diameter at near the apex of about 1 ma, to a pointed base, prominently 10-ribbed, 
the ribs hispidulous, slightly flattened and more nearly with 2 faces than with 3, 
one being more convex than the other, thus the transverse cross section midway of 
achene would be not quite circular in outline; pappus plumose, 6-7 nan, long. 
The type specimen. No, 10966,is deposited at the Gray Herbarium, and 
was collected October 4, 1934, in Newton Count; 
, This species was collected in thr alities 
in Newton County, and representative material 
herbaria.
