GYMNOLOMIA TRIPARTITA. Stem slender, glabrous, nearly ter-

others alternate, deeply 3-parted, dark green and scabrous above, 
much paler and grayish tomentulose beneath, 1 to 2 inches long, 
nearly as broad; segments oblong, obtuse, 2 to 3 lines broad, entire 
or with one or two irregular obtuse lateral teeth: petioles short, 
cuneate-winged: inflorescence corymbose; pedicels 8 lines to 14

glabrescent: ray flowers about 11, yellow, oblong, 33 lines long: 
disk conical, 4 lines in diameter: chaff strongly keeled, terminated 
by a short subulate tip.—Collected by L. C. Smith, at Cuicatlan, 
altitude 1,800 feet, 22 October, 1894 (No. 239). 
PERYMENIUM JALISCENSE. Caudex short, thick, an inch in 
diameter, giving off numerous fibrous descending roots and sev- 
eral erect or decumbent slender scabrous furrowed stems about 2 
feet high: leaves opposite, short-petioled, oblong to linear-lanceo- 
late, obtuse, serrate or subentire, narrowed at the base, condupli- 
cate, spreading and somewhat recurved, about 2 inches long, 3 to 
6 lines wide, 3-nerved, scabrous; the lowest pairs considerably 
shorter and broader ; petioles about a line long: heads about 3 
together at the ends of the almost naked branches: peduncles 
very unequal: involucral scales in 3 series; the outer broadly 
ovate, obtuse, minutely cinereous-pubescent, ciliated upon the mar- 
gin; the inner longer, about 2 lines in length: rays 8, unequal, 
about 3 lines long, more than two-thirds as broad, bright-yellow, 
minutely 8-toothed at the apex, ciliolate toward the base and 
upon the nerves on the outer surface: mature achenes about 14 
lines long, minutely pubescent toward the apex.—Collected by 
Dr. Edward Palmer, Rio Blanco, Jalisco, August, 1886 (No. 310), 
and also by C. G. Pringle, on rocky hills near Guadalajara, 23 
August, 1893 (No. 5426). Dr. Palmer’s specimen has been 
referred to. P. Cervantesii DC. by Dr. Watson, Proc. Am. Acad. 
xxii, 427, but it has been compared with the type at Geneva 
through the kindness of Dr. Casimir De Candolle and Monsieur 
Buser and proves to be quite distinct, nor does it appear to be a 
form of P. Mendezii DC., as suggested by Dr. Watson, which has 
an umbellate inflorescence. The plant is habitally marked by its 
strongly conduplicate and somewhat recurved leaves.
