ROBINSON. DIAGNOSES OF TROPICAL AMERICAN PHANEROGAMS. 619 



graciliter tubulosis supra mediam partem paulo in fauces ampliatis 

 granulosis 4 mm. longis .limbum versus purpureo-violaceis, dentibus 

 limbi brevissimis obtusis ; pappi setis albis corolla distincte brevioribus ; 

 acbaeniis 5-gonis glabris 1.1 mm. longis basim versus paulo decrescen- 

 tibus. — Alturas de Oaxaca, Mexico, 1800 m. alt., 20 February, 1907, 

 Prof. C. Conzatti, no. 1738 (type, in bb. U. S. Nat. Mus., fragments in 

 hb. Gray). A species somewhat approaching E. oresbium Robinson in 

 many of its more technical characters, but readily distinguished by its 

 hastate-angled leaves, more globular inflorescence, purple pubescence, 

 etc. 



Eupatorium ramonense, n. sp., herbaceum vel basi paulo lignes- 

 cens a basi valde decumbens multirameum, ramis oppositis teretibus 

 flexuosis foliosis viridibus pubescentibus ascendentibus 1.5-2 dm. vel 

 ultra altis ; foliis oppositis petiolatis ovato-lanceolatis argute serratis 

 vel biserratis acuminatis basi obtusis vel saepe plus minusve cuneatis 

 trinerviis 3-4.5 cm. longis 1.6-1.8 cm. latis supra atroviridibus minute 

 pubescentibus subtus laete viridibus in nerviis breviter sparseque pilo- 

 sis, petiolis 0.8-3 cm. longis hispidulis ; capitulis 75-floris longipedi- 

 cellatis 1 cm. diametro in cymis multicapitulatis quasi fastigiatis ; 

 pedicellis filiformibus 2-3.5 cm. longis erectis breviter pubescentibus ; 

 bracteis lineari-lanceolatis acutis 3-5 mm. longis ; involucri campanu- 

 lati squamis subaequalibus (exterioribus 2-3 brevioribus) lanceolati- 

 linearibus attenuatis viridibus 2-3-nerviis breviter hispidulis 4-5 mm. 

 longis ; corollis laete albis 3.8 mm. longis glabris vel sparse pilosis, 

 tubo proprio gracili 1.7 mm. longo, faucibus subcylindrici-campanulatis 

 distincte ampliatis, dentibus limbi deltoideis brevissimis ; achaeniis 

 nigris 2 mm. longis 5-angulatis in costis sursum hispidulis apicem 

 basimque versus paulo decrescentibus. — In shady moist places, form- 

 ing compact masses, San Ramon, Durango, Mexico, 21 April-18 

 May, 1906, Dr. Edward Palmer, no. 74 (type, in hb. Gray). This 

 species is nearly related to E. petiolare Moc, but is readily distin- 

 guished by its smaller ovate -lanceolate (never cordate) and much 

 smoother leaves, as well as by the somewhat harsher non-glandular 

 pubescence of the pedicels and involucral scales. 



Melampodium dicoelocarpum, n. sp., gracile 4 dm. altum ; caule 

 dichotomo flexuoso striato-costato viridi sparse pubescenti vel puberulo 

 nodos versus atropurpureo, internodiis ca. 1 dm. longis ; foliis oppositis 

 graciliter petiolatis ovato-rhomboideis tenuibus acuminatis paucidenta- 

 tis basi abrupte acutatis vel etiam acuminatis 3-nervatis supra laete 

 viridibus sparse pilosis subtus paulo pallidioribus subglabris 3.5-6 cm. 

 longis 1.2-3.3 cm. latis ; petiolo 5-10 mm. longo ; pedunculis filiformi- 

 bus 3-5 cm. longis in dichotomis caulis solitariis nutantibus vel etiam
