culis 5-10 cm. longis apice saepe nutantibus ; involucri anguste ovoidei 
1.5 em. longi basi rotundati vel paulo turbinati pallidi vel purpureo- 
tincti squamis 5 alte connatis a lineis binis glandularum linearum no- 
tatis apice aureis obtusis tomentosis; flosculis liguliferis 5 ; ligulis

—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 
em. latis pinnatim nervatis firmiusculis utrinque glabris laxe reticulatis 
apice rotundatis basi late cordatis, dentibus cuspidatis, nervis venisque 
utrinque prominulis, petiolo gracili nudo 14-16 em. longo basi vix 
dilatato ; folio caulino inferiore radicalibus simili sed minore basi obtuso 
nec cordato petiolo 12 cm. longo flexuoso nec appendiculato nec au- 
riculato ; folio caulino superiore multo minore oblongo dentato, petiolo 
2 em. longo basin di pliato ca pl te ; corymbis 
compositis planis ca. 50-capitulatis ; bracteis linearibus ; capitulis ca. 
13-floris contiguis ; involucri simplicis haud calyculati campanulato- 
subeylindrici 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 Holwayana Robinson, n. sp., herbacea erecta 1-2 m. alta ; 
caule téreti medulloso striato 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 sinuato-
