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 

 y^ 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 T. Pringlei (f). 



T. Jaliscanum ROSE, 1. 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 T. -peltatum in its small leaflets with small rounded 

 teeth (f). 



T. Cuernavacanum ROSE, 1. c. 187. 1899. 



About 2 feet high, branching above, somewhat pubescent, 

 never glaucous: leaves twice ternate; leaflets roundish, i 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 (f). 



T. Pringlei WATS. Proc. Am. Acad. 25: 141. 1890. 

 T. -pubigerum PRINGLE, ex Rose, 1. c. 187. 1899. 



About 2 feet high, glabrous : leaves i to 2 times ternate ; leaf- 

 lets usually peltate, suborbicular, y z to 2 inches across, coarsely 

 5~9-toothed, not glandular : inflorescence an open panicle, with 

 slender nodding pedicels ; flower polygamo-dioecious : 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 (f). 



Var reticulatum ROSE, 1. 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 (f). 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.
