214 PITTONIA. 
Mississippi, collected 19 Oct., 1898. From the specimens it 
appears to be a tall plant, with long slender branches that 
must be trailing, or at least reclining. 
C. rLACCIDUM. Tall. like the last, more leafy, the inter- 
nodes shorter, the whole plant, seemingly glabrous, but stem 
and branches obscurely puberulent: leaves elongated-tri- 
angular, or the lower ovate-trigonous, either truncate at 
base or abruptly tapering to the short petiole, the largest 
4 inches long including the petiole, all of very thin tex- 
ture, not notably veiny, very lightly crenate, glabrous 
beneath and rather copiously gland-dotted, above glandless 
and very obscurely and sparsely strigulose: cymes almost 
sessile: heads very small: flowers deep red-purple: achenes 
sparsely resin-dotted throughout. 
River Junction, Gadsden Co., Florida, Geo. V. Nash, n. 
2572. Very different from the last by its thin-membrana- 
ceous deep green veinless foliage which is devoid of indu- 
ment, but very glandular beneath. 
C. NEPETHFOLIUM. Firmly erect, about 2 feet high, 
branched almost from the base, a strong floriferous branch 
from the axil of each leaf, both stem and branches rather 
strongly villous: leaves deltoid-ovate, the larger 2 inches 
long, on petioles of one inch or less, all exactly crenate, the 
crenatures about 12 on each margin, all of thin texture, 
the upper face green and thinly strigose pubescent, beneath 
villous-hirsutulous along the veins and sparsely so between 
them: heads in compact cymes; involucres broad-campanu- 
late, the flowers short, reddish, or purplish: achenes also 
short, sharply angled and much dotted with resin-globules: 
pappus more slender than usual, indistinctly broader at 
base, most of the bristles notably tortuous.
