 — Dry soil of fields near Uruapan, Michoacan, Mexico, 25 January, 

 1907, C. G. Pringle, no. 10,361 (type, in hb. Gray). This species has 

 much in common with P. linifolia Seaton, but differs from it in having 

 more deeply colored rays and obtusish not at all caudate-acuminate 

 teeth of the involucral cup. 



Cacalia Goldsmithii Robinson, n. sp., perennis herbacea erecta, cau- 

 dice parvo ovoideo sursum fulvo-lanato ; caule subrecto vel leviter flex- 

 uoso glabro simplici gracili 1-2-foliato 6-7 dm. alto ; foliis radicalibus 

 longe petiolatis ovatis repando-dentatis vix lobatis 1 dm. longis 6-9 

 cm. latis pinnatim nervatis firmiusculis utrinque glabris laxe reticulatis 

 apice rotundatis basi late cordatis, dentibus cuspidatis, nervis venisque 

 utrinque prominulis, petiolo gracili nudo 14-16 cm. longo basi vix 

 dilatato ; folio caulino inferiore radicalibus simili sed minore basi obtuso 

 nee cordato petiolo 12 cm. longo flexuoso nee appendiculato nee au- 

 riculato ; folio caulino superiore multo minore oblongo dentate, petiolo 

 2 cm. longo basin versus modice ampliato caulem amplectente ; corymbis 

 compositis planis ca. 50-capitulatis ; bracteis linearibus ; capitulis ca. 

 13-floris contiguis ; involucri simplicis haud calyculati campanulato- 

 subcylindrici squamis ca. 8 oblongis 7 mm. longis 2-3 mm. latis dorso 

 planiusculis apice obtusiusculis ciliatis ; corollis albido-ochroleucis 8 mm. 

 longis fere ad mediam partem quinquifidis, lobis oblongis obtusis ; pappi 

 setis sordidis tubum proprium vix superantibus ; achaeniis compressis 

 breviter oblongis glabris. — On level pastures, Hacienda San Marcos, 

 Jalisco, Mexico, alt. about 350 m., 12 July, 1905, Rev. P. Goldsmith, 

 no. 8 (type, in hb. Gray). This species is probably nearest C. Palmeri 

 Gray, but differs in its thinner smooth ovate rather than suborbicular 

 leaves as well as in its larger more numerously flowered heads. 



Cacalia Hoi wayana Robinson, n. sp., herbacea erecta 1-2 m. alta ; 

 caule tereti medulloso striate atropurpureo glanduloso-puberulo ; ra- 

 dicibus carnosis ; foliis longipetiolatis orbicularibus subcentrali-peltatis 

 9-13-sinuato-lobatis supra laete viridibus subtus vix pallidioribus 

 utrinque sparse pubescentibus laxe reticulato-venosis 1.5-2 dm. diame- 

 tro, lobis acutis 2-4 cm. longis 1.5-5 cm. latis oblongis sinuate-
