• EUPATORIUM PYCNOCEPHALUM Less. — Santa Rosa, De- 

 part.Santa Rosa, alt. 3-4,000^ May and November 1893, 

 Heyde & Lux 3,406 in part and 4,229; Jumaytepeque, De- 

 part. Santa Rosa, alt. 6,000^\ January 1893, Heyde & Litx 

 4,219; San Miguel Uspantan, Depart. Quiche, alt. 6-12, ooo^ 

 April 1892, Heyde & Ltix 3,39/. Evidently the same as E, 

 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 E, 

 malvaefolium DC, and the two should probably be merged. 

 The present material has the involucral scales of E. Schult::ii, 

 but the heads are more than 20-flowered, as in E, malvaefol- 

 tum, a larger number than is credited to the former species. 

 Reported as nine feet high.

Eupatorium vernonioides, n. sp. of Osmia. — Shrubby and 



leafy, with the general aspect of a Vernonia, more or 1 

 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.S™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 

 not distinct, but obscure and irregular, the outer scales 

 especially Inclined to a purplish tinting: achenes glabrous 

 (poorly developed in the material at hand).— Cenaguilla, De- 

 part. Santa Rosa, alt. 4,000", November 1892, Heyde &■ Lux
