This plant appears to stand near Eleutheranthera, with which it 

 shares many characters. It differs, however, markedly in its anthers, 

 which are appendiculate and connate, in its non-accrescent involucre, 

 and densely puberulent achenes. Furthermore in Eleuthcranthera 

 the achenes have a nipple- shaped contracted summit which is here 

 lacking. 



Perymenium globosum Robinson, n. sp., caule quadrangulato 

 griseo-brunneo angulis rotundatis faciebus sulcatis, internodiis 7-9 cm. 

 longis ; foliis oppositis petiolatis ovato-oblongis serratis rugosis acumi- 

 natis basi rotundatis vel abrupte breveque cuneatis supra scabris 

 strigillosis subtus vix pallidioribus scabriusculis in nervis venisque his- 

 pid ulo-pubescentibus 8-12 cm. longis 4-5 cm. latis, petiolo 1.8 cm. 

 longo flexuoso supra canaliculato ; capitulis corymbosis, corymbis com- 

 positis 8-18 cm. latis ; bracteis inferioribus foliaceis, bracteolis lineari- 

 subulatis 3-5 mm. longis, pedicellis filiformibus flexuosis 1-2 cm. longis 

 adpresse griseo-pubescentibus ; involucri squamis ovatis acutis viridi- 

 bus ca. 3 mm. longis ; disco valde convexo ; flosculis liguliferis ca. 7, 

 ligulis linearibus aureis patentibus 6-8 mm. longis; paleis oblongis 

 conduplicatis apice vix acutiusculis flavidis ; capitulis fructiferis de- 

 presso-globosis 8 mm. diametro ; achaeniis disci obovatis crassiusculis 

 atrobrunneis plus minusve bullatis 2 mm. longis 1 mm. latis glabris a 

 basi styli conica indurata coronatis ; pappi aristis ca. 15 flavidulis in- 

 aequalibus plerisque 1 mm. longis. — Uruapan, Michoacan, Mexico, 

 C. G. Prlngle, no. 10,354. This species is nearly related to P. cerbesi- 

 noides DC, but differs in having broader and less attenuate pales, 

 greener involucral scales, and leaves 3-nerved not from the base but 

 from a point nearly 1 cm. above the base.
