158 Robinson and Greenman—Meuican Plants. 
hillsides near Guadalajara, 10 October, 1889 (No. 2490). Dis- 
tributed as Cacalia peliata H.B.K., which however differs in its 
more numerously flowered heads, more leafy inflorescence, in the 
presence of long linear calyculate bracts, commonly exceeding 
those of the involucre, also in the more divaricately cleft lobes of 
the leaves. 
CACALIA OBTUSILOBA. Radical leaves subcentrally peltate, 
orbicular in outline, 6-lobed to the middle, green and glabrate 
above, somewhat paler and puberulent beneath, a foot in diame- 
ter; lobes broad, again irregularly and obtusely lobed and 
mucronate-denticulate; cauline leaves not seen: stem subsuleate, 
sordid-tomentulose: inflorescence thyrsoid-paniculate, . tomentu- 
lose: heads many, 5-flowered, calyculate at base: involucral 
scales 5, oblong-linear, obtusish, green-backed, and tomentulose, 
24 to 3 lines long: flowers light colored.—Collected by C. G. 
Pringle, on the Sierra de San Felipe, altitude 6,000 feet, 17 
November, 1894 (No. 5840). 
CACALIA PAUCICAPITATA. Simple, slender, erect, 3 to 4 feet 
high: base tuberous, sending off a few stout fibres: stem terete, 
and as well as the petioles, pedicels, and under surface of the 
leaves densely white arachnoid-lanate; the indumentum being 
more or less deciduous: radical leaves sinuate-pinnatifid, 4 to 6 
inches long, two-thirds as broad, green and glabrate above, lateral 
lobes in 3 to 5 divaricate pairs, oblong, acutish, subentire or 
again more or less divaricately lobed; petioles about equalling 
the blades; cauline leaves only one or two similar near the base: 
inflorescence a simple raceme: heads 6 to 8, large, 40—50-flowered, 
9 or 10 lines broad, calyculate with loose linear scales: inner 
involucral bracts about 13, broadly oblong, narrowed to an 
obtusish ciliolate apex: corolla tube slender, 4 lines long, thick- 
ened at the base, throat short; segments narrow: achenes 
elliptic, densely silky-villous.—Colleeted by C. G. Pringle, on 
dry slopes under oaks, Sierra de Clavellinas, altitude 7,000 feet, 
25 October, 1894 (No. 6018). 
CACALIA SILPHIIFOLIA. Radical leaves ovate-oblong, very 
‘deeply cordate, obtuse, shallowly and somewhat doubly sinuate- 
dentate, nearly a foot in length, 5 inches in breadth, glabrous, 
pinnately veined, scarcely paler beneath ; midrib purplish; petioles 
wingless, purplish, striate, nearly a foot and a half in length, 
woolly at the base; lower cauline leaves. unknown, the upper 
reduced to very narrow linear dried bracts, 6 lines to an inch 
in length: stem green, striate, puberulent; floral leaves filiform : 
heads very numerous in a much-branched compound corymb, 
about 8 flowered: scales of the involucre 6 to 8, oblong, acute, 
strongly carinate, 23 lines long: corollas 5 lines long, segments 
two-thirds as long as the tube: achenes ribbed, nearly 2 lines 
in length.—Collected by C. G. Pringle, on the Sierra de las 
Crucis, State of Mexico, 21 August, 1892 (No. 5251). Radical 
leaves resembling in outline those of Silphium terebinthinaceum 
L. They are thinner and less strongly reticulated than in the
