Schiedeanum Schrad. Very variable in foliage, but the in- 
tergradations are so complete that no varietal distinctions can 
be drawn. The variations extend from narrowly lanceolate 
with long acuminate apex to cordate ovate and even rotund 
towards and in the inflorescence. Reported to be a little 
more than three feet high. 
EUPATORIUM SCHULTZII Sch. Bip.—Teocinte, alt. 2, 500%, 
February 1893, Heyde & Lux 4,515. Entirely too near &. 
malvaefolium DC., and the two should probably be merged. 
The present material has the involucral scales of Z. Schultzt2, 
but the heads are more than 20-flowered, as in E. malvaefol- 
zum, a larger number than is credited to the former species. 
Reported as nine feet high. 
Eupatorium yernonioides, n. sp. of Osm1a.—Shrubby and 
leafy, with the general aspect of a Vernonia, more or less 
glandular pubescent in the region of the inflorescence and apt 
to be sparsely so upon the leaf veins (especially beneath), 
otherwise glabrous: leaves short-petioled, thickish but hardly 
coriaceous, lanceolate with tapering base and apex (perhaps 
the lower leaves broader and more rounded at base), entire 
or obscurely mucronulate-toothed, with prominent midrib and 
conspicuously reticulated beneath, dark green and somewhat 
shining above, paler and often reddish tinged beneath, 15 
to 20™ long, 2.5 to 4.5 broad: heads rather numerous in the 
open somewhat leafy cymes, about 9™ high and 40- to 60- 
flowered: lower scales of the cylindrical or urn-shaped in- 
volucre short and broad, with ciliate margins and glandular 
pubescence on the back, upwards becoming gradually nar- 
rower, longer, more delicate, less glandular and ciliate until 
the innermost linear scales are almost smooth; all obtuse ex- 
cept a short apiculation of the innermost ones; the striations 
hot distinct, but obscure and irregular, the outer scales 
€specially inclined to a purplish tinting: achenes glabrous 
(Poorly developed in the material at hand). “-Cenaguilla, De- 
yee Santa Rosa, alt. 4,000°, November 1892, Heyde & Lux
