TROPICAL AMERICAN EUPATORIEAE. 263 
obtusa munitis; achaeniis 5-angulatis 1.2 mm. longis deorsum de- 
crescentibus in costis hispidulis; pappi setis 5 delicatule capillaribus 
minute scabratis corollam aequantibus.— Mexico: on wet rocks, 
Barranca de Tenampa, Zacuapan, Vera Cruz, March, 1910, Dr. C. A. 
Purpus, no. 4925 (TYPE Gr.). 
This species, very naturally sent out as a Eupatorium, is clearly 
from its definite pappus-bristles of the genus Fleishmannia. It is, 
however, certainly distinct from any hitherto described species of the 
genus. While it approaches most nearly in its general habit and 
foliar characters F. arguta (HBK.) Robinson, it differs in many im- 
portant characters. The heads are much more numerous, more 
definitely aggregated into flat-topped corymbs, and are much smaller. 
The florets are very much less numerous. The pubeseence of the 
stem is of long conspicuous jointed hairs, while in F. arguta the stems 
are merely puberulent. 
Kuhnia oreithales, spec. nov., herbacea erecta; caule tereti 
pluricostulato brevissime crispeque puberulo foliaceo 4-6 dm. vel 
ultra alto virgato vel supra mediam partem ramoso; ramis adscendente 
patentibus; foliis lineari-lanceolatis plerisque adscendentibus integer- 
rimis minute puberulis utrinque viridibus subtus paullo pallidioribus 
crebre punctatis 5-8 em. longis 2-6 mm. latis tenuibus 1-nerviis 
margine paullo revolutis; capitulis ca. 18-floris thyrsoideo-corymbosis 
gtaciliter pedicellatis nutantibus 11-12 mm. altis; involucri squamis 
interioribus anguste oblongis acutis tenuibus striatis viridibus vel 
partim purpureis subglabris sed apicem versus atomiferis et plus 
minusve ciliolatis, squamis extimis multo brevioribus subsquarroso- 
Tecurvatis; corollis ca. 6 mm. longis albidis vel purpureo-tinctis 
glabris sed in limbo extus atomiferis; achaeniis maturitate 6 mm. 
longis fusco-brunneis glabriusculis— Mexico: Chihuahua: near 
Colonia Garcia, 16 August, 1899, Townsend & Barber, no. 260 (T¥PE 
Gt.,.U.-S.;: Mo. etc.), distributed as Coleosanthus corymbosus, with 
which it has no close resemblance even of general habit, not to men- 
tion its plumose pappus. XK. oreithales, in its thin smoothish leaves 
and in habit, resembles the northeastern K. eupatorioides L., but it 
differs from that species in its entire leaves and nodding heads, as 
well as its more acute inner involucral scales ; and, of course, it is 
8eographically remote. To K. oreithales may be referred the follow- 
specimens: near Colonia Garcia, 1-20 August, 1899, E. 
Nelson, nos. 6208 (Gr.), 6216 (Gr.); near Parral, 28 September, 1898, 
E. H. Goldman, no. 124 (Gr.); Sierra Madre and Sierra Santa Barbara, 
near La Providencia, alt. 1980-2440 m., E. W. Nelson, no. 5016 (Gr.).
