518 MINNESOTA BOTANICAL STUDIES. 
apically lobed or crenate: flowers polygamous in an open pan- 
icle: akenes flattened, obliquely oblong, being nearly straight 
on edge, base tapering but sessile, both faces 2—3-veined ; styles 
\ inch long, rather persistent. August. Morelos, south of 
Mexico City. Rose, 1. c. 186, redescribes and figures this, 
plate 21. He concludes that DeCandolle’s type may have been 
found in the same region. Type in U. S. Nat. Herb. 7448, 
distributed as 7. Prznglez (+). 
T. Jaliscanum Ross, |. c. 187. 1899. 
Stems tall, glabrous and glaucous; upper leaves ternate, the 
leaflets peltate, orbicular, 6 to 10 toothed, glabrous: inflores- 
cence a large open panicle: carpels narrowly elliptical, some- 
what cuneate at base, strongly nerved. Quoted from Rose by 
whom it was first collected on tableland in northeastern Jalisco. 
Differs from 7. peltatum in its small leaflets with small rounded 
teeth (f). 
T. Cuernavacanum Ross, |. c. 187. 1899. 
About 2 feet high, branching above, somewhat pubescent, 
never glaucous: leaves twice ternate; leaflets roundish, 1 inch 
across, palmate, broadly crenate: inflorescence an open panicle ; 
flowers perfect; anthers linear; akenes 2 lines long, narrowed 
at both ends, subsessile, one side straight, 3—-4-ribbed; styles 
long. Morelos, south of Mexico City (+). 
i.Pringlet Wars, Proc. Am, Acad.) 25 : 140.1890: 
T. pubigerum PRINGLE, ex Rose, 1. c. 187. 1899. 
About 2 feet high, glabrous: leaves 1 to 2 times ternate: leaf- 
lets usually peltate, suborbicular, %4 to 2 inches across, coarsely 
5-9-toothed, not glandular: inflorescence an open panicle, with 
slender nodding pedicels; flower polygamo-dicecious: anthers 
linear, long apiculate: akenes compressed, semi-ovate, straight 
on one side, 6-8-ribbed, 2 lines long; styles long, somewhat 
persistent. June-August. Near the capital of Jalisco, and the 
coast slope of the same state (fT). 
Var reticulatum Ross, |. c. 188. 1899. 
A lower, somewhat pubescent form: leaflets peltate, entire 
or 3-5-angled, dark green above, strongly net-veined: flowers 
in a narrow panicle; peduncles nodding in fruit. Western 
foothills of Tepic Territory (+). The type 3372 in U. S. Natl. 
Herb. is a form of the same variety with the leaflets shallow- 
round-lobed, and some of them only subpeltate.
