Llatris canescena sp, nov. 
c anescens sp. nov. Plant perennial from a thickened, elongated 
corm, growing in moist or muddy places or in shallow water, and frequently 
with the basal portion of the stem, as much as 5 cm. long, becoming root-like 
and bearing relatively long, spreading or descending prop roots, and with the 
upper end greatly thickened and densely sheathed by the fibrous remnants of 
earlier basal leaves, the fibers erect and up to 3 cm. long; when the basal 
portion of the stem has become root-like there is usually only one stem, and 
this is stout, terete, about 5 mm. in diameter, and very densely pilose with 
white hair, but when this condition does not obtain and 8 or more stems arise 
from the corm, they are smaller, 3 mm. in diameter or less, and, while densely 
pubescent, the hair is much shorter and is grayish instead of white; the basal 
leaves are linear and elongated, about 3 mm. wide, and gradually shortened and 
become lanceolate above, tapering gradually from the broad base to the acute 
apex, in the inflorescence becoming bract-like, and all leaves are moderately 
to densely pilose on both surfaces, below more or less masking the midrib and 
the punctate depressions; the heads are axillary, with a short and hairy peduncle 
about 1 long of sessile, and have 3-5 flowers; the involucres are turbinate, 
mm. high and about half as broad, the outer bracts much shorter than the 
imer ones scarious-margined, pubescent, ciliate, punctate and resiniferous. 
hile the inner ones are oblong, 2 mm. broad, prominently 5-nerved at the glabrate 
midnerve ^d usually 2 lateral nerves extending well towards the obtuse, 
purplish apex, broadly scarious-margined, not ciliate, and finely pubescent and 
resiniferous above the glabrate basal portion to the scarious apex; the achenes 
are pointed at the base and just below the apex have a major diamefeer of 1.5 mm. 
and towards the base a minor diameter of 1 mm., 4 mm. long or less, minutely hairy, 
prominently 3-angled, one face broadly convex and 5-nerved, the two other faces 
flattened, with one or more nerves or nerveless, and occasionally one of these 
faces has a prominent nerve on an angle, giving the effect of a 4-angled achene 
teving one n^row face and with a total of 10 nerves; the pappus is barbellulate, 
and is 5 or 6 mm. long. ’ 
M 4 . /I specimen. No. 10963, was collected October 4, 1934, in 
ewton County Texas,^and is deposited at the Gray Herbarium. Inasmuch as 
additional material wis collected in September, 1936, at a considerable distance 
laJlelTJh" ^ probable that this species may be found 
S ^s^^S / ® southeast Texas, where it grows in open.
