 Michoacan or Guerrero, Mexico, alt. 2200 m., 17 Feb. 1899, Langlasse, 

 n. 893 (hb. Gray, hb. Berol.). 



Eupatorium Cursonii, n. sp., ramis atropurpureis teretibus fusco- 

 tomentellis, internodiis brevibus 8 mm. longis ; foliis oppositis lineari- 

 oblongis attenuatis supra bullato-reticulatis sparse puberulis subtus 

 reticulato-venosis tomentosis 9 cm. longis 8 mm. latis crassiusculis 

 margine leviter crenulatis valde revolutis, petiolo ca. 1 mm. longo ; 

 capitulis 2-3 in summis ramorum axillaribus permagnis ca. 80-floris, 

 involucri squamis subaequalibus lanceolatis, exterioribus subcoriaceis 

 2 cm. longis 4 mm. latis striatulis dorso granulari-puberulis apice sub- 

 filiformi-attenuatis, interioribus angustioribus et tenuioribus ; recep- 

 taculo paleifero saltern ad marginem, paleis 2 cm. longis ad apicem fere 

 capillaceum attenuatis; corollis anguste tubulosis glaberrimis 1 cm. 

 longis, dentibus 5 brevissimis patentibus atropurpureis ; antheris line- 

 aribus apice valde appendiculatis basi integerrimis ; styli ramis clavatis 

 planiusculis 6 mm. longis atropurpureis ; achaeniis linearibus 7 mm. 

 longis 5-angulatis in costis minute scabratis ; pappi setis ca. 50 fere 

 1 cm. longis, plurimis exteriorum brevioribus. — Collected at Arequipa, 

 Peru, by Mr. Curson. The sole specimen of this clearly marked species 

 is in the herbarium of the British Museum of Natural History. It had 

 evidently been in the herbarium of Nuttall, who had recognized its 

 novelty and assigned it a specific name under the genus Campuh- 

 clinium. Unfortunately Nuttall's manuscript name has already been 

 used in Eupatorium and therefore cannot be now taken up. In habit 

 and probably in its affinities E. Cur.<onlt approaches E. BalUi Oliv., 

 from which, however, it differs decidedly in its subequal involucral 

 bracts.
